SN/T 4669-2016 in English

This standard outlines a testing method for evaluating the flame spread resistance of hanging materials in imported and exported textiles. The procedure involves the use of an open test chamber to simulate real-world conditions. The method provides detailed guidelines on sample preparation, testing conditions, and measurement techniques. It specifies the equipment required, including the test chamber, ignition source, and measurement instruments. The standard also defines the criteria for determining the flame spread characteristics of the materials under test. The testing process is designed to ensure consistency and reliability in the results. The standard covers the entire testing procedure from setup to data analysis. It is intended for use by laboratories and testing institutions involved in the assessment of textile products.
