Significance and Use
These test methods are designed to determine the purity of rubber chemical accelerators.
Since the results of these test methods are based on an integrated peak area, it is assumed that all analytes of interest are resolved from interfering peaks.
1.1 These test methods cover the determination of the purity of present commercially available rubber chemical accelerators in the range from 80 to 100 % by high performance liquid chromatography (HPLC) using ultraviolet detection and external standard calculations.
1.2 Expertise in HPLC is necessary to the successful application of these test methods.
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.
