1 Scope This standard specifies the terms and definitions, test apparatus, specimen, conditioning, test procedure, post-test inspection, judgment of test result and test report, etc. of the fire-resistant performance test for external wall insulation system applied to building facade. This standard is applicable to the fire-resistant performance test for non-load bearing external wall insulation system installed on the building facade. This standard is not applicable to the fire-resistant performance test for external wall insulation system of respiration glass curtain wall structure installed on the building facade. 2 Normative References The following referenced documents are indispensable for the application of this document. For dated reference, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.
