Significance and Use

4.1 The purpose of this test method is to establish a common method by which manufacturers, calibration laboratories, and users of hydrometers may inspect, verify, or calibrate hydrometers.

4.2 The goal is to provide a standard method that is simple, easily understood, and will produce reliable results.

1. Scope

1.1 This test method describes the principles, apparatus, and procedures for the inspection, calibration, and verification of ASTM glass hydrometers. This test method is applicable to ASTM hydrometers and may be used for other general hydrometers of the constant-mass, variable-displacement type.

1.2 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. The metric equivalents of inch-pound units may be approximate.

1.3 This standard does not purport to address all of the safety concerns, 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.
