These Regulations come into operation (simultaneously with Parts I, II, V and VI of the Weights and Measures Act 1963) on the 31st January 1964. They substantially replace the Weights and Measures Regulations 1907, as amended, which cease to have effect with the repeal on that date of the Weights and Measures Act 1904.
The Regulations, which apply to all weighing and measuring equipment for use for trade of the classes specified in regulation 1, deal with the materials, principles of construction, inspection, testing, passing as fit for use for trade and stamping of such equipment.
The present Regulations in substance repeat the provisions of the earlier Regulations, subject to some drafting alterations and to such adaptations as are necessary to enable the present Regulations, operating within the framework of the Weights and Measures Act 1963, to produce the same effect as was produced by the earlier Regulations operating within the framework of the Acts repealed by the Act of 1963. Except as respects the matters mentioned below, the alterations have not made any changes of substance in the requirements under the earlier Regulations.
The only changes of substance which have been made are to extend to all equipment in the class to which they relate, those requirements which the Board of Trade formerly imposed in relation to particular equipment in those classes as a condition of granting a dispensation from the general requirements of the earlier Regulations. The changes are as follows:—
