Significance and Use
4. Significance and Use
4.1 Color is caused by impurities in the bisphenol A. The acceptable amount of color depends on the end-use of the bisphenol A.
4.2 This test method can be used for internal quality control or for setting specifications.
1. Scope
1.1 This test method describes the procedure for determination of the Platinum-Cobalt Color of bisphenol A (4,4???-Isopropylidenediphenol) dissolved in methanol.
1.2 This test method has been found applicable for the determination of Platinum-Cobalt color of bisphenol A between 20 and 100 color units.
1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.4 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 hazard statements, see Section 8.
