Weights and Measures (Working Standards and Testing Equipment) (Testing and Adjustment) (Jersey) Order 1975
THE ENVIRONMENT AND PUBLIC SERVICES COMMITTEE, in pursuance of Articles 9(3) and 38(1) of the Weights and Measures (Jersey) Law 1967,[1] orders as follows –
Commencement [see endnotes]
PART 1
GENERAL
1 Interpretation
(1) In this Order the symbols and abbreviations employed to indicate units of weight and measure refer to the units in relation to which those symbols and abbreviations are set out in Schedule 1.
(2) Except as otherwise indicated, the limits of error specified in Schedule 2 are limits in excess or deficiency.
(3) A reference in this Order to an enactment shall be construed as a reference to that enactment as amended by any subsequent enactment.
2 Working standards and testing equipment
Working standards of the following classes provided pursuant to Article 9(1) of the Weights and Measures (Jersey) Law 1967 (hereinafter referred to as the “Law”)[2] for use by inspectors namely, linear measures, capacity measures and weights, and testing equipment of the following classes so provided, namely, beamscales, balances, test weights, egg grading machine test poises, displacement plungers and pipettes, shall be tested in accordance with the relevant provisions of this Order –
(a) at intervals of not more than 6 months; and
(b) in the case of any standard or article of equipment which is thought not to be accurate within the relevant limit of error, before use.
PART 2
WORKING STANDARDS
3 Linear measures
(1) Working standard linear measures shall be tested by comparison with a Jersey standard of equivalent length being either a separate standard or a standard marked by divisions on a longer Jersey standard which has been certified under Article 8 of the Law as being so marked.
(2) Where such a comparison reveals an error which exceeds the relevant limit specified in Part 1 of Schedule 2 the working standard shall not be further used until it has been so adjusted that any error is within that limit.
4 Weights
(1) Working standard weights shall be tested by comparison with an equivalent Jersey standard weight.
(2) The comparison shall be made on a balance which complies with the requirements of Article 6 and is such that the weight required to produce a displacement of 1 division of restpoint is less than the amount specified in Part 2 of Schedule 2 as the limit of error for the weight which is being tested.
(3) If the comparison reveals a difference which exceeds the relevant limit of error the weight which has been tested shall not be further used until it has been so adjusted that any error is within that limit.
5 Capacity measures
(1) In this Article “working standard capacity measure” includes in the case of a multifiller measuring instrument every measure incorporated in that instrument.
(2) A working standard capacity measure shall be tested as a measure of the amount which it is intended to measure, or if it is subdivided to be a measure of more than 1 amount, as a measure of its maximum purported capacity and as a measure of at least 1 amount indicated by a subdivision.
(3) Such a measure shall be tested –
(a) where the test relates to an indicated imperial measurement not exceeding 1 gal. or an indicated metric measurement not exceeding 51., by comparison with an equivalent Jersey standard;
(b) in any other case by comparison with not more than 2 Jersey standards of an equivalent total capacity or with a Jersey standard of 1 gal. or 51. (used the requisite number of times).
(4) The accuracy of any tolerance marks adjacent to any graduation tested pursuant to paragraph (2) shall also be tested.
(5) Water shall be used for testing.
(6) Only Jersey standards or working standards or articles of testing equipment tested in accordance with this Order shall be used for testing.
(7) Where testing reveals an error which exceeds the relevant limit specified in Part 3 of Schedule 2, the tested measure shall not be further used until it has been so adjusted that any error is within that limit.
PART 3
TESTING EQUIPMENT
6 Balances and beamscales
(1) Balances and beamscales shall be tested by using Jersey standard or working standard weights.
(2) Testing shall be carried out by determining –
(a) the weight required to be added to the balance or beamscale when fully loaded in order to produce one division change of restpoint;
(b) the discrepancy between the restpoint with the balance or beamscale unloaded and the mean value of the restpoints obtained before and after the interchange of loads equivalent to the full capacity, that is to say, the length of arm error; and
(c) 12 successive restpoints with the balance or beamscale fully loaded (the load being removed or replaced between the determination of each restpoint) and calculating the range of each 3 successive determinations.
(3) Where –
(a) the weight required to be added as aforesaid exceeds the relevant amount specified in Part 4 or Part 5 of Schedule 2;
(b) the said discrepancy exceeds 2 divisions of the scale in the case of a balance or one division in the case of a beamscale; or
(c) the average of the 4 ranges determined in accordance with paragraph 2(c) of this Article exceeds 2 divisions of the scale in the case of a balance or beamscale of a capacity of not less than 56 lb or 25 kg or one division in any other case,
the relevant balance or beamscale shall not be further used as testing equipment until it has been so adjusted as to eliminate the excess.
7 Test weights
(1) Test weights shall be tested by comparison on a beamscale which complies with the requirements of –
(a) Article 6; or
(b) the Weights and Measures (General Provisions) (Jersey) Order 1968[3] for a Class B beamscale of that capacity for use for trade.
(2) Jersey standard weights or working standard weights shall be used for testing test weights.
(3) Where a test reveals an error exceeding the relevant limit specified in Part 6 of Schedule 2, the tested weight shall not be further used until it has been so adjusted that any error is within that limit.
8 Egg grading machine test poises
(1) Egg grading machine test poises shall be tested by the use of a balance of a capacity not exceeding 1 lb or 200 g.
(2) Where a test reveals that a poise is more than 0.75 grains too heavy or more than 0.25 grains too light it shall not be further used until it has been so adjusted that any error is within those limits.
9 Pipettes and displacement plungers
(1) Pipettes and displacement plungers shall be tested with water, the temperature of which is as near as practicable to 20° centigrade. For purposes of any test of imperial equipment, 1 fl. oz. of water shall be deemed to weigh 28.3 g and for the purposes of any test of metric equipment, 10 ml of water to weigh 9.97 g.
(2) A pipette shall be tested as a measure of its maximum purported capacity and as a measure of at least 1 amount indicated by a subdivision by filling it to the level of the graduation, discharging it and weighing the water discharged.
(3) A displacement plunger shall be tested by weighing the amount of water it displaces from a displacement vessel.
(4) The limit of error as respects a pipette shall be the relevant weight indicated in the second column of Part 7 of Schedule 2 in relation to its maximum purported capacity.
(5) The limit of error as respects a displacement plunger shall be the relevant weight indicated in the second column of Part 8 of Schedule 2.
(6) Where testing reveals an error which exceeds the relevant limit, the pipette or displacement plunger in question shall not be further used until it has been so adjusted that any error is within that limit.
