ASTM E126-92(1998) - 10.10.1998
 
1. Scope

1.1 This test method describes the principles, apparatus, and procedures for the inspection and verification of glass hydrometers of the constant-mass, variable-displacement type. It is intended to apply to ASTM hydrometers as well as to glass hydrometers in general.

1.2 The values stated in inch-pound units are to be regarded as the standard. The metric equivalents of inch-pound units may be approximate.

1.3 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.
