1.2The characteristics to be examined include:
1.2.1Sensitivity at all loads,
1.2.2Lever arm ratio,
1.2.3Damping ratio (for instruments without accessory dampers),
1.2.4Period of oscillation,
1.2.5Precision, and
1.2.6Linearity and calibration of accessory devices that provide on-scale indication of weight.
1.3This standard does not purport to address all of the safety concerns 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.
