WITHDRAWN, NO REPLACEMENT
1.1 This practice covers the measurement of the ultraviolet absorption spectrum of any rubber chemical that is soluble in a spectroscopic solvent. The rubber chemical may possess absorption maxima in this region (approximately between 200 and 400 nm).
1.2 The recommended practice further differentiates between rubber chemicals on the basis of differences in their absorption spectra, both in the spectral position of the absorption bands and in the absorptivities at selected wavelengths.
1.3 The use of this practice implies that the conditions of measurement and sample preparation be reported for a rubber chemical under examination (see 13.2).
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.
