Standard Test Method for Rubber Deterioration-Surface Ozone Cracking in a Chamber
|Publication Date:||10 November 1999|
|ICS Code (Rubber):||83.060|
1.1 This test method covers the estimation of the resistance of vulcanized rubber to cracking when exposed to an atmosphere containing ozone. The rubber specimens are kept under a surface tensile strain, and the ozone content or partial pressure in the test chamber is maintained at a fixed value.
1.2 The values stated in SI units are to be regarded as the standard. The values in parentheses are for information only.
1.3 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. For a specific hazard statement, see Note 1 and 7.1.
Note 1-Ozone is a hazardous chemical.
