(d)     Interchangeability

When, for an equal-armed weighing instrument, the load and the working standard weights are interchanged on the load receptacles, the indicated weight must not change by more than twice the limit of error.

(e)     Limit of error

When at full capacity the error of a weighing instrument must not exceed the limit of error.

(2)        In this regulation, the "limit of error" of a weighing instrument means the limit of error for that instrument (according to its capacity) specified in Schedule 2 or Schedule 3 as the case may be.

Provided that for an automatic weighing machine, an electronic balance, a high accuracy balance or a self-indicating weighing instrument other than a weighbridge, the limit of error for a load of one-third or more but not greater than two-thirds of the capacity is -

(i)      the conventional verification interval marked on the chart, display or identification label; or

(ii)     if the verification interval is not so marked, the smallest interval between sub- divisions; or

(iii)    any other limit of error decided by the Chief Inspector.

18.    (1)        The Inspector shall carry out the following tests on a platform machine or mechanical weighbridge at verification -

(a)     Linearity

The upper surface or edge of the steelyard must be in one plane from the zero graduation to the nose end;

(b)     Removable parts

The instrument must not have readily removable parts (except any counterbalance supporting counterpoise weights);

(c)     Stops

The instrument must have stops to prevent any poise weight from moving past the zero graduation;

(d)     Load rail

Any load rail must be not less than 10 mm from other rails and if two load rails overlap or have a bridging piece, there must be not less than 5 mm gap between overlapping or bridging parts.

(e)     Range of balance

(i)      in a mechanical platform machine the range of balance must not be greater than one-half percent of the capacity of the instrument and must not be less than one-eight percent of that capacity each way from the centre of travel of the ball;

(ii)     in a mechanical weighbridge the range of balance must not be greater than 1 percent of the capacity of the instrument and must not be less than one-quarter percent of that capacity each way from the centre of travel of the ball;

(f)     Travel of steelyard

The travel of the steelyard each way from the hori- zontal position must not be less than 10 mm;

(g)     Position of load

When a load of as nearly as practicable one-quarter of the capacity of the instrument is displaced from the centre of the platform to a position near an end or a corner of the platform, the indicated weight must not change by more than half the limit of error;

(h)     Counterpoise weights

Each individual counterpoise weight, drop weight, tare bar, weight bar or other device used to increase the capacity of the instrument must be tested;

(i)      Forward and backward

Results must be the same whether the test is carried out forward or backward; and for a document platfrom machine, weighbridge or overhead weigher must be correct when the load is run on or off the platform or load rail;

(j)      Locking handle or relieving gear

If the instrument is fitted with a locking handle or relieving gear, the results must be correct when the instrument is put slowly into and out of action.

(2)     The Inspector shall check that a weighbridge has -

(a)     Drainage

adequate drainage with no accumulation of water, mud or debris in the pit;

(b)     Approaches

smooth, straight and horizontal approaches for a distance of at least the length of the platform at each end of the weighbridge;

(c)     Clear view

the building with the chart or steelyard so cons- tructed that the operator has an unobstructed view of the whole platform;

(d)     Platform protection

the platform so protected that vehicles can only go onto it or leave it at the ends;

(e)     Foundations

adequate foundations to support it at maximum load without movement;

(f)     Counterpoise weight

if not fitted with a tare-beam, a counterpoise weight (of distinctive shape from other counterpoise weights for the instrument) which accurately compensates for the weight of any loose receptacle or frame used with the instrument and which has the words "TARE WEIGHT" legibly and conspicuously stamped on its edge.
