For research, development, and quality control purposes, it is advantageous to determine the composition of rubbers in cured, compounded products.

This test method provides such composition analysis utilizing an infrared technique.

1.1 These test methods, based on infrared examination of pyrolysis products (pyrolyzates) and films can be used for rubber identification.

1.2 These test methods are applicable to rubbers in the raw state and, when compounded, both in the cured and uncured state.

1.3 The values stated in SI units are to be regarded as 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. Specific precautionary statements are given in Section 17.
