ASTM D8266-19 PDF

Scope: 1.1 This test method covers the determination of trace impurities in bisphenol A (4,4'-Isopropylidenediphenol) by reverse-phase gradient high performance liquid chromatography (HPLC). It is generally meant for the analysis of bisphenol A of 99.5 % or greater. 1.2 This method is applicable to bisphenol A samples containing impurity concentration between 2 and 400 mg/kg. Users of this method believe it is linear over a wider range. 1.3 In determining the conformance of the test results using this method to applicable specification, 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 a specific hazard statement, 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.
