    Significance and Use

    This test method can be used for research or for quality control to characterize isocyanates used in polyurethane products.

    For toluene diisocyanate, results from this test method can relate to reactivity or performance in polyurethane systems.

    1. Scope

    1.1 This test method measures the color of clear liquids. It is applicable only to materials whose color-producing bodies have light-absorption characteristics similar to those of the platinum cobalt color standards used. (See Test Method D1209 and Note 1.)

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

    Note 1—This standard is equivalent to ISO 6271-1:2004.
