Description

ASTM D4659-03

Historical Standard: Standard Test Methods for Polyurethane Raw Materials: Determination of Specific Gravity of Isocyanates

ASTM D4659

Scope

1.1 These test methods determine the specific gravity of toluenediiosocyanate and crude methylene-bis-(4-phenylisocyanate). These test methods also are applicable to many other liquids. (See Note 1.)

1.1.1 Test Method A Specific gravity by pycnometer, for high-accuracy determination.

1.1.2 Test Method B Specific gravity by hydrometer, for a less accurate, but rapid, determination.

1.2 The values stated in SI units are to be regarded as the standard. The values given in brackets are for information only.

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. For specific warning and precautionary statements see Notes 2 and 3.

Note 1—There is no equivalent ISO standard.
