Organization: ASTM International
Publication Date: 1 September 2006
Status: inactive
Page Count: 4
ICS Code (Auxiliary materials and additives for plastics): 83.040.30
ICS Code (Thermoplastic materials): 83.080.20
significance And Use:

These test methods are suitable for quality control, as specification tests, and for research. Color is an important property of urethane products.

scope:

1.1 These test methods measure visually the color of clear polyester and polyether liquids. They apply only to materials whose colors have light-absorption characteristics similar to those of the standards. An alternative method is Test Method D 1209 (see ).

1.2 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

Although Test Method A of these test methods and ISO 4630-1:2004 differ in some details, data obtained using either are technically equivalent. Although Test Method B of these test methods and ISO 6271-1981 differ in some details, data obtained using either are technically equivalent.
