In the EN ISO 6940 standard published by the International Standards Organization (ISO), when vertically oriented textile fabrics and industrial products in the form of single or multi-component fabrics (coated, quilted, multi-layered, sandwich structures and similar combinations) are exposed to a small, defined flame, A test method for measuring flammability is presented. This test method is used to evaluate the properties of textile fabrics in response to flame contact under controlled conditions.
The effect of stitches on the behavior of fabrics can be determined by this test method. For this, the seam is positioned in the test specimen so that it is exposed to the test flame. Where applicable, trims are tested under this standard as part of the fabric assembly in which they are or will be used.
The test method presented in the EN ISO 6940 standard is one of two closely related test methods for the flammability of textile fabrics. These two test methods are:
The test methods defined in EN ISO 6940 and 6941 standards are widely applied throughout the textile and garment manufacturing industry, particularly in the testing of fabrics and other woven material products. These tests are used to determine the flame spread rate for vertically oriented samples.
For each exposure condition, at least six samples of the product are tested. Three specimens are cut longitudinally and three specimens transversely. These tests cover products processed into single-component or multi-component materials (such as coated, quilted and multi-layered). If the surface areas of a product are markedly different, more than one test must be performed to evaluate the product. Therefore, the exact number of samples is determined only after the first inspection.
Among the numerous test, measurement, analysis and evaluation studies it provides for businesses in various sectors, our organization also provides flammability testing services of vertically oriented samples for the burning behavior of textile fabrics within the scope of EN ISO 6940 standard, with its trained and expert staff and advanced technological equipment.
