The standard provides operational procedures for the conditioning and handling of non-metallic materials in natural and man-made climate tests. The standard emphasizes the importance of specimen handling, identification, Encasement, transport and conditioning before, during and after testing. The specification calls for minimizing the effects of non-testing periods on specimens to guarantee the integrity of materials and the accuracy of test results. The standard also covers conditioning details and long-term storage, but does not address specific efflorescence exposure processes. Users are required to follow relevant safety practices and comply with regulatory requirements. This standard has no equivalent ISO standard and conforms to the principles of international standardization.
