THE WEIGHTS AND MEASURES (EQUIVALENTS FOR DEALING WITH DRUGS) RULES
1.
Citation and interpretation
(1)

These Rules may be cited as the Weights and Measures (Equivalents for Dealing with Drugs) Rules.
(2)

In these Rules, unless the context otherwise requires—

"mixture" means any liquid preparation intended for administration by mouth which consists of one or more drugs dissolved or suspended in an appropriate vehicle, but does not include an elixir, emulsion, linctus or syrup;

"table" means one of the tables in the Schedule.
2.
Equivalent for weights and volumes

Except as provided in rules 3 and 4, any unit of measurement mentioned in the second column of a table shall be treated for the purpose of any dealing with drugs as the equivalent of the units set opposite thereto in the first column of that Table, and for any fraction of a grain not specifically mentioned in the first column of Table 1 the equivalent for such purpose shall be treated as the corresponding fraction of the equivalent of one grain set out in the second column of that table.
3.
Equivalent for doses of liquids
(1)

Where a prescription for any drug states that the quantity of each dose is to be either one fluid drachm (fl. dr.) or two fluid drachms, the equivalent of that quantity for the purposes of dispensing the prescription shall be treated as five millilitres or ten millilitres respectively.
(2)

Where a prescription for any drug which is a mixture states that the quantity of each dose is to be one-half of one fluid ounce (fl. oz.) the equivalent of that quantity for the purpose of dispensing the prescription shall be treated as ten millilitres.
(3)

Where a prescription for any drug which is a mixture other than a mixture formulated for administration to children states that the quantity of each dose is to be two fluid drachms, the equivalent of that quantity for the purpose of dispensing the prescription shall be treated as ten millilitres:

Provided that if the prescription refers to a formulation of the drug with a dose of one-half of a fluid ounce and the drug is prescribed at the normal strength, the equivalent of two fluid drachms for the purpose of dispensing the prescription shall be treated as ten milliliters of the drug at half the single strength.
(4)

Where any prescription to which this rule refers specifies quantity of ingredients of any drug in the total quantity to be dispensed, this Rule shall be treated as applying to the quantity of each such ingredient in each dose.
4.
Equivalent for total quantity prescribed for external or bulk oral preparation
(1)

Where in a prescription for an external preparation or a bulk oral preparation, the total quantity to be supplied is expressed in ounces avoirdupois or apothecaries the metric quantity supplied shall be on the basis that one ounce avoirdupois or apothecary is equivalent to twenty-five grams.
(2)

Where in a prescription for an external preparation or a bulk oral preparation, the total quantity to be supplied is expressed in fluid ounces (fl. oz.) the metric quantity supplied shall be on the basis that one fluid ounce is equivalent to twenty-five millilitres.
(3)

For the purposes of this Rule, Table 3 or 4 shall be used.
(4)

Where any quantity of an external preparation or bulk oral preparation is expressed in terms of one or more of the units mentioned in the first column of Table 3 or 4 is greater than one pound or one pint, the equivalent for the purpose of any dealing with the prescription shall be treated as the corresponding multiple of the equivalent for one pound or one pint, as the case may be, plus the equivalent of any residue of less than a pound or pint as ascertained from the appropriate tables.
(5)

In paragraph (4), "corresponding multiple" in relation to a quantity means the number of times that quantity will divide into units of one pound or one pint as the case may be.
5.
Control of sale and supply
(1)

Where any manufacturer, wholesale dealer or retail dealer sells or supplies any drug after the commencement of these Rules he shall, if the order or prescription relating to such a dealing is expressed in terms of a unit of measurement specified in the first column of any of the tables or of any such fraction as is mentioned in rule 2 carry out such dealing in terms of the equivalent quantity ascertained in accordance with that rule.
(2)

The provisions of rules 3 and 4 shall not apply to imported medicaments that are sold in their original containers as packaged by the manufacturer.

PART I – PRELIMINARY
1.
Citation and application
(1)

These Rules may be cited as the Weights and Measures Rules.
(2)

These Rules shall not, so far as they relate to material, apply to weights, measures, weighing or measuring instruments used in the manufacture of explosives.

[L.N. 56/1996, r. 3.]
2.
Interpretation

In these Rules, unless the context otherwise requires—

"absolute maximum permissible error" means the value of the maximum permissible error without regard to sign;

"analogue indicator" means an indicator on which the value of the physical quantity measured is indicated by an indicator and a graduated scale one of which is fixed and the position of the other is a continuous function of the magnitude of the physical quantity being determined;

"capacity", in relation to a weighing instrument (other than a belt conveyor weigher or an egg grading machine), means the maximum load, excluding the additive tare capacity, which the instrument is constructed to weigh as marked or indicated on the instrument in accordance with the Act or these Rules;

"composite measure" means a measure of length where one of its principal graduations is an end surface or edge and the other is a line, hole or mark;

"correct", in relation to an instrument, means correct within the maximum permissible error specified for the instrument in these Rules;

"dial" includes a dial carrying a linear fan chart or circular scale;

"digital indicator" means an indicator on which the value of a physical quantity is represented by a series of aligned digits which change abruptly such that no indications can be obtained between digits;

"dispensing measure" means any measure designed and intended for use in pharmaceutical dispensing;

"end measure" means a measure of length whose principal graduations are two end surfaces or edges of the measure;

"graduation" means lines or notches the distance between which determines the scale division on analogue scales; and numbers on digital scales shall be considered as graduations;

"instrument" means weighing or measuring instrument;

"licensee" means a person who possesses a valid licence under these Rules;

"maximum permissible error" means the extreme values of an error as specified in these Rules for weights, measures, weighing and measuring instruments;

"maximum safe load" means the maximum static load which can be carried by the instrument without the instrument altering its metrological qualities;

"minimum capacity", in relation to a weighing instrument, means the value of the load below which the weighing results are subject to excessive relative errors;

"partial totalization indicating device" means the device indicating the weight of the loads conveyed by the belt over a limited period of time;

"principal graduations" means two graduations the distance between which represents the nominal length of a measure of length;

"reading distance" means the shortest distance at which an observer is able to freely approach the indicating device on an instrument in order to take a reading under normal conditions of use; and the approach shall be considered to be free if there is a clear space of at least 0.8m. in front of the indicating device;

"rejected", in relation to a weight, measure or instrument, means examined or verified by an inspector and found not to comply with the requirements of the Act or of these Rules;

"repaired", in relation to a weight, measure or instrument, means that the weight, measure or instrument since it was last stamped has had some adjustment, other than balancing in the case of a weighing instrument, made to it;

"repairer" means a person licensed to engage in the repair or overhauling of weights, measure or instruments;

"rounding error" means the difference between the digital indication or printing and the indication the instrument would give with analogue indication or printing;

"scale division" means the smallest subdivision of the scale in the case of continuous (analogue) indication, or the difference between two consecutive indicated or printed values in the case of discontinuous (digital) indication or printing;

"stamping station" means any place appointed under section 27 of the Act;

"test indicator", in relation to a belt conveyor weigher, means an indicating device with a scale division smaller than that of the totalization indicating device and intended for the testing of the belt weigher;

"to repair", includes making any adjustment to any weight, measure or instrument other than the adjustment of the balance arrangement which is required under these Rules in respect of specified types of weighing instruments;

"totalization indicating device", in relation to a belt conveyor weigher, means a device for indicating the overall total weights of all loads conveyed by the belt.
3.

Weights, measures and instruments shall be submitted for testing and tested in a clean condition, and if necessary the inspector may call upon the owner or user to clean them.
4.
Denomination

The denomination of a weight or measure or the capacity of an instrument, if not marked in full, shall be indicated only by one of the abbreviations specified in the First Schedule.
5.
Examination on premises

Weights, measures and instruments may be examined on the premises of a repairer or dealer:

Provided that the actual traveling expenses of the inspector and the cost of transport of standards shall be paid by the repairer or dealer.
6.
Duties of person submitting weights, measures or instruments

The inspector may require any person submitting any weight, measure or instrument for verification—

(a)

to take it sufficiently apart to enable him to examine the working parts; and
(b)

to provide sufficient labour for the proper and expeditious handling of the standards or any material which is to be used in the testing of any such weight, measure or instrument.
7.
Weights, measures and instruments not to be admitted for verification

The inspector shall not admit for verification—

(a)

TESTS
PART I – TESTS TO BE APPLIED TO EGG-GRADING MACHINES
1.

In this Schedule the following expressions shall have the following meanings respectively—

“capacity” means—

(a)

in relation to a type “A” machine, the number of those weighing units in the machine whose functions is to grade eggs into one of the specified grades; and in determining that number in the case of a machine in which several weighing units grading eggs into the same specified grade are served by the same feed track, two or more such units are to be counted as a single weighing unit;
(b)

in relation to type “B” machine, the product of multiplying the number of those weighing units whose function is to grade eggs into one or more of the specified grades by the number of different specified grades into which the machine is designed to grade eggs;

“test poise” means a counterpoise for use in the testing of egg grading machines, being a counter poise approved by the Director for such use as respects its form and the material of its construction.
2.

For the purpose of any test referred to in this Schedule, an egg-grading machine shall be treated as grading any test poise correctly if, but only if—

(a)

it grades that poise into the appropriate grade, that is to say, the grade specified in column 1 of Table 14 of rule 135 appropriate to the weight range specified in column 2 of that table within which the weight of that poise falls; or
(b)

in the case of a poise of a weight less than the weight range appropriate to the specified grade “sub-grade”, it does not grade that poise into any of the specified grades.
PART II – EVERY EGG GRADING MACHINE SHALL BE TESTED IN THE FOLLOWING MANNER
A – FIRST TEST
1.

For the purpose of this test (hereinafter referred to as the “first test”), the inspector shall select a set of test poises consisting of the number of pairs of test poises equivalent to the number of different specified grades into which the machine is designed to grade eggs, each pair of poises being selected in relation to a different grade and so that one of the poises in the pair weighs half a gram more and the other half a gram less than the minimum of the weight range specified in column 2 of Table 14 of rule 135 appropriate to that grade.
2.

In the case of a type “A” machine, the set of test poises shall be fed indiscriminately into the machine in the manner in which eggs would be fed into it in the course of its normal operation, each poise being fed into the machine along the feed track or (in the case of a multiple track machine) along each feed track, the number of times specified in column 2 of Part 3 of this Schedule in relation to a machine of that capacity.
3.

In the case of a type “B” machine, each poise in the set of test poises shall be fed indiscriminately into each weighing unit in the machine the number of times referred to in paragraph 2, each poise being fed into the unit, either—

(a)

by placing it on the feed track serving the weighing unit; or
(b)

by placing it by hand directly into the weighing unit.
4.

If the machine fails to grade all the poises correctly and—

(a)

in the case of a machine bearing a stamp which has not been obliterated or defaced, the aggregate number of incorrect gradings does not exceed that specified in column 3 of Part 3 of this Schedule in relation to a machine of that capacity; or
(b)

in the case of any other machine, the aggregate number of incorrect gradings does not exceed that specified in column 4 of Part 3 of this Schedule, in relation to a machine of that capacity, the machine shall be subjected to the second test specified hereunder.
B – SECOND TEST
5.

For the purpose of the second test, the inspector shall select a further set of test poises consisting of each pair of test poises used in the first test which, or one of which, was incorrectly graded in that test.
6.

In the case of a type “A” machine each pair of test poises so selected shall be fed into the machine along the feed track, or (in the case of a multiple track machine) along each feed track, serving each weighing unit by which that pair of poises, or one of that pair, was incorrectly graded in the first test and each test poise of the pair shall be fed into the machine along the relevant feed track such number of times as (together with the number of times that poise was fed into the machine along that feed track in the course of the first test) equals 25.
7.

In the case of a type “B” machine, each pair of test poises so selected shall be fed only into each weighing unit by which that pair of poises, or one of that pair, was incorrectly graded in the first test; and each poise of the pair shall be fed into the relevant weighing unit—

(a)

such number of times as (together with the number of times that poise was fed into that weighing unit in the course of the first test) equals 25; and
(b)

in the following manner, that is to say, either—

(i) by placing it on the feed track serving that weighing unit; or
(ii) by placing it by hand directly into that weighing unit.
8.

The machine is correct and satisfies the appropriate test for the purpose of paragraph (2) of rule 136 if, and only if—

(a)

when tested pursuant to the first test, it correctly grades all the test poises;
(b)

when tested pursuant to the first and second tests the number (under both such tests) of incorrect gradings of the test poises in each pair by each weighing unit—

(i) in the case of a machine bearing a stamp which has not been obliterated or defaced, does not exceed 13;
(ii) in the case of any other machine, does not exceed 11.

Provided that—

(i) where any goods are pre-packed and sold by retail on the same premises, no statement as to the name and address of the manufacturer or packer of the goods shall be required to be made on the package;
(ii) where, by reason of the smallness of the package, it is not reasonably practicable to indicate the name and address of the manufacturer or packer of any goods on the package, it shall be sufficient compliance with paragraph (a) of this rule if the package bears a trade mark or such other mark or inscription as would enable the purchaser to identify the manufacturer or packer of such goods;
(iii) where any goods manufactured or packed outside Kenya are imported into Kenya, the package containing such goods shall, in addition to the name and address of the manufacturer or packer of the goods, bear the name and address of the importer of such goods.

(3)

Where a package is provided with an outside wrapper or container, such wrapper or container shall also contain the declarations which are required to appear on the package, except where such wrapper or container is transparent and the declaration on the package itself is easily and clearly readable through such outside wrapper or container.

The minimum height of any letter or number in the declaration shall be 2mm.
(5)

Any person who contravenes any of the provisions of this Rule commits an offence.

[L.N. 106/1999, r. 2(d).]
8.
Declaration of quantity
(1)

Every declaration of quantity on a package shall specify the quantity of goods to which it relates without any reference to words, figures or any other marks implying an approximation, or any expression which tends to create an exaggerated or misleading impression as to the quantity of the goods contained in the package:

Provided that—

(i) in the case of thread or any other material whose length is likely to vary if subjected to tension, the quantity declaration shall also include the tension under which the length of such thread of material was determined.
(ii) in the case of soap in the form of a bar, cake or tablet, the quantity declaration shall specify the minimum net weight guaranteed at the time of manufacture and either the total fatty matter in the soap expressed as a percentage of the declared weight, or the grade of the soap.
(2)

Except in the case of goods specified in the First, Second, Third, Fourth, Fifth and Sixth Schedules, the declaration of quantity of goods contained in a package shall be in terms of—

(a)

weight, if the goods are solid, semi-solid or viscous, or a mixture of solid and liquid, or
(b)

measure of capacity, if the goods are liquid:

Provided that in the case of a solid product contained in a free-flowing liquid which is sold as such, the declaration of quantity shall be in terms of the drained weight of the solid product.
(3)

In the case of a product packed in a container designed to deliver the product under pressure, the declaration of quantity shall state the net quantity in weight that will be expelled when the instructions for use are followed and the propellant therein shall be included in the net quantity statement.
(4)

In declaring the net weight of goods contained in a package, the weight of wrappers and other materials used to pre-pack the goods shall be excluded:

Provided that where a package contains a number of small items each of which is separately wrapped and it is not reasonably practical to exclude the weight of such immediate wrappers from the weight of the items, the net weight declared on the package of such items or on the label thereof may include the weight of the immediate wrappers, if the total weight of such individual wrappers does not exceed—

(a)

eight per cent, where the immediate wrapper is waxed paper or any other paper with wax or aluminium foil under strip; or
(b)

six per cent, where the immediate wrapper is any other type of paper, of the total weight of all the items contained in the package minus the weight of the immediate wrapper.
(5)

Any person who contravenes any of the provision of this rule commits an offence.

[L.N. 106/1999, r. 2(e).]

[L.N. 106/1999, r. 2(h).]
13.
Procedure for determination of quantity in packages
(1)

For the purpose of ascertaining the net quantity of goods in any package, the inspector may carry out tests on a sample of such goods and the sample shall be drawn from a batch of the packages in the manner specified in the Ninth Schedule.
(2)

The tests mentioned in paragraph (1) of this rule shall be carried out in accordance with the method specified in the Tenth Schedule and the inspector shall enter the detailed results of the tests in the form set out in the Eleventh Schedule.
14.
Deficiency in quantity of pre-packed goods

The declaration of quantity on a package of pre-packed goods shall be deemed to be correct if, as a result of the tests carried out under rule 13 of these Rules, it is found that—

(a)

any deficiency thereof is not more than—

(i) in the case of a bottle whose net contents do not exceed 250 millilitresor 250 grams, 10 per cent; or
(ii) in any other case, 3 per cent of the net quantity marked on the package; and
(b)

the average quantity of the goods in a sample of—

(i) all packages, in the case of a batch containing less than thirty packages; or
(ii) thirty packages, in the case of a batch containing thirty but not more than five hundred packages; or
(iii) 10 per cent of the total number of packages in a batch, in the case of a batch containing more than five hundred packages and the test is not destructive; or
(iv) twenty packages in the batch, in the case of a batch containing more than five hundred packages, and the test is destructive,

is equal to or more than the net quantity marked on the package.
15.
Penalties

Any person who commits an offence under these Rules shall be liable to a fine not exceeding twenty thousand shillings or to imprisonment for a term not exceeding three years or to both.

NINTH SCHEDULE

[r. 13(1).]

MANNER OF SELECTION OF SAMPLES
1.

In this Schedule the following expressions shall have the following meanings—

"destructive test" means a test where it is necessary to open a package and take out the goods contained therein for the purpose of determining their net quantity, and—

(a)

it is not practicable to so re-fill or re-pack the goods after the test as to make the package a saleable one, or
(b)

the goods are such that they are likely to become unfit for consumption or use after they have been taken out of the package.

"non-destructive test" means a test which is not destructive.

"sample size" means the number of packages to be selected as samples.
2.

For the purpose of any test to determine the net quantity of goods contained in any package, the Inspector shall select a sample from a batch of such packages and the sample size shall be as specified in Table 1.

Number of packages

Sample size

Destructive test

Non-Destructive test

Less than 30

8 packages

All packages in batch

30 but not more than 500

13 packages

30 packages

More than 500

20 packages

10 per cent of number of packages in the batch.
3.

The Samples referred to in paragraph 2 shall be selected at random in the manner specified in paragraph 4 and 5.
4.

Where it is necessary to take a sample of packages stored in warehouse, godown or any other place, such a sample shall be selected at random from every batch of such packages and shall be picked out from the top, bottom, centre, right, left, front and rear of the stocks so that the sample may adequately represent the package in the batch.
5.

Where it is necessary to take samples from the place where the package is being filled—

(a)

such sample shall be selected from among the packages which have already been filled, or
(b)

the requisite number of empty containers may be taken and each of them marked for proper identification. The tare weight of each marked container shall then be accurately noted and thereafter the containers shall be introduced at random in the packing process. After the containers are filled they shall then be tested to ascertain whether they do contain the net quantity of the goods as declared on the container.

TENTH SCHEDULE

[r. 13(2)]

PROCEDURE FOR DETERMINATION OF QUANTITY

[L.N. 106/1999, r. 2(m).]

1.

Determination of the net weight—

(a)

where empty containers are available, ten such containers shall be weighed and the arithmetic mean of their total weight shall be taken to represent the tare weight of every package in the sample. The net weight of the goods contained in each package in the sample shall then be obtained by subtracting the tare weight from the gross weight of the package.
(b)

where empty containers are not available, three packages from the sample shall be opened and the weight of the contents of each package as well as the weight of each empty container determined. The average weight of the three empty containers shall be taken to represent the tare weight of each of the remaining packages in the sample, and the net weight of each of the remaining packages in the sample, and the net weight of goods contained in each of these packages, shall be obtained by subtracting the tare weight so determined from the gross weight of the package.
(c)

where it is necessary to take samples from the place where the packages are being filled, the following procedure shall be used—

(i) the number of empty packages, depending on the size of the sample in accordance with Table 1 of the Ninth Schedule, shall be selected and suitably marked to distinguish them from the other packages being filled;
(ii) the weight of each package shall then be determined and recorded on the empty package and also on the form specified in the Eleventh Schedule;
(iii) the empty packages shall then be filled by introducing them in a random manner in the packing process, and such introduction shall be adequately spread over the duration of one hour’s production.
(iv) the marked packages shall then be taken out after completion of the filling and sealing operations and each filled package shall be re weighed;
(v) the net weight shall be obtained by deducting the tare weight, determined in accordance with paragraph (c)(ii) from the gross weight.
(d)

The Inspector shall enter the results of his tests in Form A specified in the Eleventh Schedule, along with such other observations as he may wish to make on the basis of his tests.
2.

Determination of liquid contents by volume—

(a)

if the specific gravity of the liquid in the package is known and can be determined accurately, the method of determination of net contents by weight described in paragraph (1) may be used;
(b)

if the method described in paragraph 2(a) is not feasible, the containers shall be opened and the contents of each package poured out carefully into the appropriate volume measure;
(c)

The reading of the actual net volume of the goods in every package shall be noted carefully and recorded in Form B specified in the Eleventh Schedule.
3.

Determination of length—

(a)

if it is not possible to measure the dimensions without opening the package, the package shall be opened;
(b)

the length of the item in the package shall be measured by means of a standard steel tape of suitable length;
(c)

if the length of the item is so great that it is not possible to measure it with the tape measure and a suitable length instrument is available on the premises, that instrument shall be used after duly verifying it with the steel tape serving as a working standard of length;
(d)

the measured length of the goods in every package shall be noted carefully and recorded in Form B specified in the Eleventh Schedule.
4.

Determination of quantity of goods packed by number—

The Inspector shall take packages from the sample drawn by him in the manner specified in the Ninth Schedule and shall determine the error by actual counting of the goods in each such package and may, for that purpose open all packages.
