    1. Scope


    1.1 This test method covers procedures for the thermal and humid exposure of rigid cellular plastics. Conditions used shall be agreed upon between the purchaser and the supplier.

    Note 1—A list of commonly used exposure conditions is found in Table 1.

    1.2 The values stated in SI units are to be regarded as the standard. The values in parentheses are for information only.

    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.

    Note 2—This test method is equivalent to ISO 2796 in the sampling and calculation sections. It is not equivalent to ISO 2796 in the procedure section.
