The Weights and Measures (Amendment) Regulations 1972
These Regulations amend the Weights and Measures Regulations 1963 (S.I. 1963/1710). The main changes are that—provision is made as respects the calibration of metric spring balances;spring balances may in future be of any capacity;the rules as to the obliteration of stamps on weighing instruments which have been altered or adjusted and the limits of error applicable on their retesting are relaxed in relation to instruments which have been modified to record metric weights if notice of the modification has been given to the local chief inspector of weights and measures.
