1 Scope

This document establishes a small laboratory sieve for comparing the horizontal combustion characteristics of small samples of flexible porous polymeric materials under a small flame. The purpose is only to quickly and simply evaluate the combustion characteristics of the material itself, that is, regardless of the environmental factors of the material or the material it is made of. conditions of use of the product. Therefore, the correlation between the test results and the performance of such materials or products under actual use conditions cannot be established. sex. The test is limited to samples with a thickness greater than 5mm, and the test results of samples with different thicknesses are not comparable. This document is not intended to assess potential fire hazards in use. Note. See ISO 9772.2020 for another test method for porous plastics with a density less than 250kg/m3.The test equipment and procedures are different from those specified in this document, because It should not be assumed that they will produce the same test results.

2 Normative references

The contents of the following documents constitute the essential provisions of this document through normative references in the text. Among them, dated references For documents, only the version corresponding to the date is applicable to this document; for undated reference documents, the latest version (including all amendments) is applicable to this document. linear dimensions) Note.

3 Terms and Definitions

This document does not have terms and definitions that need to be defined.

4 Purpose of the test

Under specified conditions, compare the combustion characteristics of different materials, control the manufacturing process, and evaluate the changes before and during use are of great value. There is no correlation between the results of this test and how the material or product will perform under actual use conditions. The product should be based on The end use shall be tested by the corresponding test method. This test method is not suitable for evaluating the potential fire risk of materials or products during use. The assessment of fire risk needs to consider Factors such as gas supply, combustion intensity, and combustion products also need to be considered. Environmental factors, such as the intensity of the fire source, the arrangement of the burned materials orientation and ventilation conditions.

5 general rules

5.1 The horizontal burning characteristics measured by this test procedure are affected by factors such as density, anisotropy of the porous polymer, and specimen thickness. ......
