Protective clothing - Protection against heat and flame - Method of test for limited flame spread (ISO 15025:2000)

This standard outlines a test method for evaluating the flame spread characteristics of protective clothing designed to provide thermal and flame resistance. It specifies procedures for conducting limited flame spread tests to assess the performance of materials under controlled conditions. The methodology involves exposing the test specimen to a flame source and measuring the extent of flame propagation across the material. The results obtained from these tests are used to determine the suitability of the material for use in protective clothing applications. The standard ensures consistency in testing procedures and provides a reliable means of comparing the flame resistance properties of different materials. It includes detailed requirements for test apparatus, specimen preparation, and evaluation criteria.
