Excerpt from Specifications, Tolerances, and Regulations for Commercial Weights and Measures and Weighing and Measuring Devices: Issued September 1, 1949 Purpose - The purpose of specifications and tolerances is to eliminate from use, without prejudice to apparatus which conforms as closely as practicable to the official standards, weights and measures and weighing and meas uring devices which are false, which are of such construe tion that they are faulty - that is, which are not reason ably permanent in their adjustment or will not repeat their indications correctly - or which facilitate the per petration of fraud. Classification of Specifications - The classification of specifications into retroactive and non - retroactive re quirements is made in order that the requirements may be put into force and effect without unnecessary hardship and without wholesale condemnation of apparatus which, while not of the best construction, is nevertheless fairly satisfactory and may be used for some time without greatly prejudicing the rights of purchasers. Non-retro active specifications are those which, while clearly desir able, are not so vital that they should at once be enforced with respect to all apparatus. It is not to be expected, how ever, that non-retroactive specifications shall always re main non-retroactive; in a given jurisdiction it is entirely proper that a weights and measures official, following a careful analysis of existing conditions, fix reasonable periods for the continuance of the non-retroactive appli cation of particular specifications, at the expiration of which periods such specifications will become retroactive in their application. These periods should be of such length as to avoidundue hardship on the owners of apparatus and, in the case of some specifications, should approximate the average useful life of the apparatus in question. The periods will, of course, differ for different apparatus, and may differ for different specifications in the same code.
