   (b)   has unusual or novel features, unless it is of a design or pattern in respect of which a certificate has been issued in terms of section 13 of the Act;

 

   (c)   is not sufficiently strong to withstand the wear and tear of ordinary use in trade;

 

   (d)   is not complete in itself;

 

   (e)   is not in a clean state; or

 

   (f)   bears a manufacturer's or other mark which might be mistaken for the stamp of assize.

   (2) An assizer shall refuse to assize an instrument which-

 

   (a)   has interchangeable or reversible parts, unless the interchange or reversal does not affect the accuracy of the instrument;

 

   (b)   has removable parts, the removal of which would affect the accuracy of the instrument, unless the parts are such that the instrument cannot be used without them.

   (3) An assizer shall reject a weighing instrument which-

 

   (a)   has a scoop, pan, plate or other part which is essential to its operation, broken;

 

   (b)   has a scoop, pan or plate of such size or shape as may lead to incorrect weighing either through its fouling the housing of the scale, or because proper contact between the knife edge and bearings is disturbed;

 

   (c)   has a goods-plate which is readily absorbent on account of faulty glazing or on account of the extent to which it is cracked or chipped;

 

   (d)   has a friction plate, stay, hook or loop which is not of hardened steel or an approved material; or

 

   (e)   has packing at the knife edges which, in the opinion of the assizer, is either excessive as to the number of pieces or is in other respects unsuitable for the purpose.

   (4) An assizer shall reject an accelerating weighing instrument, other than an accelerating deadweight machine.

   (5) An assizer shall reject a weighing instrument which has not been previously assized, unless the name of the manufacturer of the instrument is marked thereon.

PART II
Weighing Instruments
(regs 11-25)

 

11.   Testing of weighing instruments

   (1) Subject to the other provisions of this regulation, a weighing instrument shall be tested by the direct application of standard weights.

   (2) An automatic weighing machine shall be tested-

 

   (a)   where practicable, by the direct application of standard weights; and

 

   (b)   by comparing the load delivered against standard weights.

   (3) Subject to the provisions of subregulation (5), a weighbridge shall be tested by the direct application-

 

   (a)   of standard weights; or

 

   (b)   of test weights provided by the owner or scale manufacturer or maintenance contractor.

   (4) Subject to subregulation (5), a weighing instrument kept in stock for sale which is tested on the premises of a dealer in or repairer of scales shall be tested by the direct application-

 

   (a)   of standard weights; or

 

   (b)   of test weights provided by the dealer or repairer, as the case may be.

   (5) When a weighing instrument is tested and sufficient standard or test weights are not available, auxiliary material may be used to make weight.

 

12.   Limits of error and sensitiveness

   (1) A weighing instrument shall be tested for error by ascertaining the weight required to overcome the error in that instrument.

   (2) A vibrating weighing instrument shall be tested for sensitiveness by loading the instrument to its capacity, or as near thereto as is practicable, with the beam or steelyard in a horizontal position and ascertaining that the addition of the amount shown in the appropriate table for an instrument of that class and capacity causes the beam or steelyard to turn.

   (3) An accelerating deadweight machine shall be tested for acceleration by loading the instrument to its capacity, or as near thereto as is practicable, with the beam at the extremity of its travel, and ascertaining that the subtraction of the amount shown in the third column of Table VI for an instrument of that capacity causes the beam to return to its initial position.

   (4) The limit of error allowed and the sensitiveness required in a weighing instrument of a particular class shall be-

 

   (a)   in the case of a new or repaired instrument, the appropriate limit of error and the sensitiveness prescribed in this Part;

 

   (b)   in the case of a weighing instrument other than an automatic weighing instrument which is not new or repaired, twice the appropriate limit of error and sensitiveness prescribed in this Part.

   (5) The limit of error allowed and the sensitiveness required in a weighing instrument of a capacity not specified in the appropriate table shall be the limit of error and the sensitiveness which bear the same proportion to the capacity of that instrument as the limits of error and sensitiveness for a similar instrument of the next lower capacity specified in the table bear to the capacity of such latter instrument.

   (6) Where a weighing instrument is tested at graduations below the capacity of that instrument, the limit of error allowed shall be-

 

   (a)   below one quarter of the capacity, one-quarter of the prescribed limit of error;

 

   (b)   one quarter of the capacity or over but not exceeding three quarters of the capacity, one half of the prescribed limit of error; and

 

   (c)   above three quarters of the capacity, the prescribed limit of error.

 

13.   Poises

   (1) Where lead is used for adjusting purposes on any poise it shall not come into contact with the beam or steelyard.

   (2) A poise shall be provided with an adjusting hole of such size, shape and design as to permit readily of necessary adjustment.

   (3) A poise shall be so constructed that no part thereof can be detached without the use of a mechanical appliance.

 

14.   Counterpoise weights

   (1) A counterpoise weight shall be marked in equivalents of 2 kg, 5 kg, 10 kg, 20 kg, 25 kg, 50 kg, 100 kg or an integral multiple of 100 kg.

   (2) A counterpoise weight used, or intended for use, on platform machines used for weighing corrosive articles, including hides and skins, shall be made of brass, nickel-steel, stainless steel or other corrosion resisting metal.

   (3) A counterpoise weight shall have only one undercut adjusting hole containing fixed lead sufficient to cover adequately the bottom of such hole, and with room to permit future adjustments.

   (4) A counterpoise weight of an actual weight of 100 g or less shall be made of brass.

   (5) Where more than one platform machine provided with counterpoise weights is kept or used by any person on any premises or on a public market, each such counterpoise weight shall be identified with the weighing instrument to which it belongs by-

 

   (a)   a number conspicuously and indelibly marked and corresponding to a number similarly marked on the pillar and on the counterbalance of the instrument; or

 

   (b)   a band of paint, of a colour in distinct contrast to the colour of the weight, on the edge of the weight, corresponding to a band of paint of the same colour on the pillar and on the counterbalance of the instrument:

 

         Provided that this subregulation shall not apply to a counterpoise weight adjusted to a direct and exact ratio of 50:1 or 100:1.

 

15.   Knife edges and bearings

   (1) Knife edges shall-

 

   (a)   be firmly secured in position;

 

   (b)   be in true parallelism; and

 

   (c)   bear throughout the entire length of the parts designed to be in contact with the bearings.

   (2) Knife edges and bearings shall be of hardened steel, agate or an approved material and the load-carrying parts shall not show scratches when tested by means of the application of a superfine smooth file.

 

16.   Balance

   (1) A weighing instrument shall be in balance-

 

   (a)   when unloaded; and

 

   (b)   where a loose receptacle or frame is used in conjunction with such instrument, when the receptable or frame is attached thereto.

   (2) Balance shall be indicated-

 

   (a)   in the case of a vibrating weighing instrument, by the beam or steelyard returning to the position of equilibrium when disturbed therefrom;

 

   (b)   in the case of a self-indicating weighing instrument or a weighing instrument provided with a graduated indicating plate or a difference chart, by the pointer coming to rest at the position of equilibrium or zero graduation with the bubble of any spirit level provided, in its true position;

 

   (c)   in the case of a counter machine constructed on the Beranger principle, by two pointers, each attached to a subsidiary beam, coming to rest directly opposite each other;

 

   (d)   in the case of an accelerating deadweight machine, by the beam, on being released from the stop under the weights-pan, falling gently to the stop under the goods-pan; and

 

   (e)   in the case of a weighing instrument which indicates the weight by means of a printed statement, by the figure nought being printed on the statement.

   (3) Balance shall not be affected when the load is removed from the instrument.

   (4) Where a weighing instrument is provided with a balance box or a balance or gravity ball, such device shall be capable of adjustment only by the use of a mechanical appliance.
