active
 Organization: ASTM International Publication Date: 1 October 2020 Status: active Page Count: 4 ICS Code (Phenols): 71.080.90
##### 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... View More

##### scope:

1.1 This test method covers 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 solution color of bisphenol A to 20 Pt-Co color units.

1.3 The following applies for the purposes of determining the conformance of the test results using this test method to applicable specifications, results shall be rounded off in accordance with the rounding-off method of Practice E29.

1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.5 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. For specific hazard statements, see Section 8.

1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
