Standard Practice for the Evaluation of Single-Pan Mechanical Balances
The following bibliographic material is provided to assist you with your purchasing decision:
Scope
1.1 This practice covers testing procedures for evaluating the performance of single-arm balances required by ASTM standards.
1.2 This practice is intended for but not limited to sensitivity ratios of 10 or better and on-scale ranges of 1000 xd or more where d = readability either directly or by estimation.
1.3 This practice can also be applied to other single-pan balances with mechanical weight changing of different capacities or sensitivities with appropriate test loads and calibration weights.
Note 1-Mechanical balances of this type have largely been replaced by automatic electronic balances incorporating a variety of operational principles. Nevertheless, some single-pan mechanical balances are still manufactured and many older balances will remain in service for years to come. One type of automatic electronic balance, the so-called "hybrid," bears considerable similarity to single-pan mechanical balances of the null type. (1)1.4 This standard does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
