Standard Test Methods for Rubber-Identification by Infrared Spectrophotometry
 N D3677

Annotation

These test methods cover rubber identification and arebased on infrared examination of pyrolysis products (pyrolyzates)and films.

These test methods are applicable to rubbers in the rawstate and, when compounded, both in the cured and uncuredstate.

Since it is customary in infrared spectrophotometry touse wavenumbers (cm?1) rather than Hertz (Hz), the unit forfrequency in the SI system, the former is employed throughoutthis test method.

This test method assumes that specimens and infraredspectra are prepared and analyzed by experienced personneland that the equipment is operated according to the manufacturer’sdirection for optimum performance. No details foroperation of infrared spectrophotometers are included in thistest method.

This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appropriatesafety and health practices and determine the applicabilityof regulatory limitations prior to use. Specific precautionarystatements are given in Section 17.
