ASTM D 3677 - 10 (Reapproved 2015) Standard Test Methods for Rubber - Identification by Infrared Spectrophotometry

Current edition approved June 1, 2015. Published September 2015. Originally approved in 1978. Last previous edition approved in 2010 as D3677 – 10ɛ1. — 21 p.
These test methods cover rubber identification and are based on infrared examination of pyrolysis products (pyrolyzates) and films.
These test methods are applicable to rubbers in the raw state and, when compounded, both in the cured and uncured state.
Since it is customary in infrared spectrophotometry to use wavenumbers (cm−1) rather than Hertz (Hz), the unit for frequency in the SI system, the former is employed throughout this test method.
This test method assumes that specimens and infrared spectra are prepared and analyzed by experienced personnel and that the equipment is operated according to the manufacturer’s direction for optimum performance. No details for operation of infrared spectrophotometers are included in this test method.
