Organization: ASTM International
Publication Date: 1 January 2000
Status: inactive
Page Count: 5
ICS Code (Rubber): 83.060
scope:

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

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

1.3 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.

1.4 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.

1.5 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.
