1.1This test method covers the evaluation of vertical members in axial compression for “full-sized” specimens with various end conditions with constant cross-sections throughout the length.
1.2This test method is limited to reinforced plastic and polymer matrix composite materials and covers the determination of the compressive properties of structural members. The method is intended primarily for members of rectangular cross section, but is also applicable to irregularly shaped studs, round posts, or special sections.
1.3This test method covers short-term axial load testing under standard indoor atmospheric conditions. It does not address: sampling, the ability of the material to carry a sustained long-term load, design load derivations, temperature effects, performance under freeze/thaw or salt spray exposure conditions, chemical/UV exposure effects, or engineering analysis/modeling needed to extrapolate the results to conditions other than those tested. Each of these factors, and potentially others, need to be considered by the design professional or product standard development committee before using the information generated by this test method to assess structural adequacy.
1.4Short sections are not covered in this test method and should be tested using a material test standard such as Test Method D6108 or Test Methods D198.
1.5The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.6This 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.7This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
