ASTM E1068-85(2009)

Standard Test Method for Testing Nonmetallic Seal Materials by Immersion in a Simulated Geothermal Test Fluid (Withdrawn 2018)

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.
SCOPE
1.1 This test method covers a procedure for a laboratory test for performing an initial evaluation (screening) of nonmetallic seal materials by immersion in a simulated geothermal test fluid.
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this 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.
WITHDRAWN RATIONALE
This test method covers a procedure for a laboratory test for performing an initial evaluation (screening) of nonmetallic seal materials by immersion in a simulated geothermal test fluid.
Formerly under the jurisdiction of Committee E44 on Solar, Geothermal and Other Alternative Energy Sources, this practice was withdrawn in January 2018 in accordance with section 10.6.3 of the Regulations Governing ASTM Technical Committees, which requires that standards shall be updated by the end of the eighth year since the last approval date.
