CONTAINED IN VOL. 09.01, 2015 Describes the percentage of residual unsaturation (double bonds in unhydrogenated butadiene) in hydrogenated nitrile rubber and is based on infrared examination of rubber films cast from solution.

1.1This test method covers the percentage of residual unsaturation (double bonds in unhydrogenated butadiene) in hydrogenated nitrile rubber and is based on infrared examination of rubber films cast from solution.

1.2This test method is applicable to all grades of hydrogenated nitrile rubber in the raw state.

1.3This 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.

1.4Since 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.

1.5The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.6This 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.
