ASTM E1068-85(2003) - 31.5.1985
 
Significance and Use

This test method is intended for laboratory screening of materials. Due to large differences in the composition, pressure, and temperature of geothermal fluids, this test method may not correlate with actual service conditions. It does not consider the effects of geothermal fluid combined with oxidizing environments, stress loading, or thermal cycling.

 
1. Scope

1.1 This test method covers a procedure for a laboratory test for performing an initial evaluation (screening) of non-metallic seal materials by immersion in a simulated geothermal test fluid.

1.2 The values stated in SI units are to be regarded as the standard.

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 specific precautionary statements, see Section 6 and 11.7.
