ASTM E1270-88-Reapproved2008<\/h3>\n

Historical Standard: Standard Test Method for Equal Arm Balances<\/h4>\n
\n

ASTM E1270<\/h4>\n

Scope<\/strong><\/p>\n

1.1 This test method can be used for testing equal-arm balances of any capacity and sensitivity. The testing procedure should enable the user to characterize his instrument sufficiently to determine whether or not it is suitable for the purpose for which it is to be used.<\/p>\n

1.2 The characteristics to be examined include:<\/p>\n

1.2.1 Sensitivity at all loads,<\/p>\n

1.2.2 Lever arm ratio,<\/p>\n

1.2.3 Damping ratio (for instruments without accessory dampers),<\/p>\n

1.2.4 Period of oscillation,<\/p>\n

1.2.5 Precision, and<\/p>\n

1.2.6 Linearity and calibration of accessory devices that provide on-scale indication of weight.<\/p>\n

1.3 This 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.<\/span><\/p>\n
