Are there any exceptions for bench (spring) dial scales?
Yes. Non-NTEP approved scales may be used commercially provided they: • Are non-price-computing, non-electric mechanical scales of 50 kg (110 lb) capacity or less, • Meet other Scale Code requirements in NIST Handbook 44, • Have a minimum of 240 scale divisions, • Are intended for Class III applications excluding precious metals and semi precious gem weighing, and • Have a division size of 1 oz or smaller if used for retail food sales and are less than 50 pounds capacity.
