Organization: ASTM International
Publication Date: 1 February 2011
Status: inactive
Page Count: 5
ICS Code (Thermoplastic materials): 83.080.20
significance And Use:

CIELAB is a visual-based scale that can be used to specify color and set color tolerances for the polyurethane industry.

Yellowness Index specifies the degree of departure of the sample... View More

scope:

1.1 This test method provides an instrumental method for measuring the CIELAB color and Yellowness Index (YI) of liquid polyurethane raw materials. The CIELAB and YI results are derived from mathematical manipulation of CIE tristimulus values in accordance with Practices E308 and E313, respectively.

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-There is no known ISO equivalent to this standard.
