Designation: D 695 – 02aStandard Test Method forCompressiv e Properties of Rigid Plastics 1This standard is issued under the fixed designationD 695; the number immediatelyfollowing the designationindicates the year oforiginal adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e ) indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the Department of Defense.1. Scope *1.1 This test method covers the determination of the me-chanical properties of unreinforced and reinforced rigid plas-tics, including high-modulus composites, when loaded incompression at relatively low uniform rates of straining orloading. Test specimens of standard shape are employed.1.2 The values stated in SI units are to be regarded as thestandard. The values in parentheses are for information only.NOTE 1—For compressive properties of resin-matrix composites rein-forced with oriented continuous, discontinuous, or cross-ply reinforce-ments, tests may be made in accordance with Test Method D 3410.1.3 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use. A specific precau-tionary statement is given in Note 11.NOTE 2—This test method is technically equivalent to ISO 604.2.
