Organization: ASTM International
Publication Date: 10 November 1999
Status: inactive
Page Count: 3
ICS Code (Thermosetting materials): 83.080.10
scope:

1.1 This test method covers the acidity, expressed as ppm of hydrochloric acid, in aromatic isocyanate or polyurethane prepolymer samples of below 100 ppm acidity. The test method is applicable to products derived from toluene diisocyanate and methylene-bis-(4-phenylisocyanate) (see Note 1).

Note 1-There are no equivalent ISO standards.

1.2 The values stated in SI units are to be regarded as the standard.

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.
