(Test Method)Standard Test Methods for Microcellular Urethane Materials
Standard Test Methods for Microcellular Urethane Materials
SIGNIFICANCE AND USE
Tests made on materials herein prescribed can be of considerable value in comparing physical properties of different materials, in controlling manufacturing processes, and as a basis for writing specifications.
Before proceeding with these test methods, reference should be made to the specification of the material being tested. Any test specimen preparation, conditioning, or dimensions, or combination thereof, and testing parameters covered in the materials specification shall take precedence over those mentioned in these test methods. If there are no material specifications, then the default conditions apply.
SCOPE
1.1 These test methods cover the preparation of a standard-size test sample and basic tests for physical property determinations of microcellular urethane materials.
1.2 The values stated in SI units are to be regarded as standard. The values given in parentheses are for information only. 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. Note 1&8212;There is no known ISO equivalent to this standard.
