EN ISO 6941 Textile fabrics - Combustion Behavior - Measurement of Flame Spread Properties of Vertically Oriented Samples

In the EN ISO 6941 standard published by the International Standards Organization (ISO), vertically oriented textile fabrics and industrial products in the form of single or multi-component fabrics (coated, quilted, multi-layered, sandwich combinations and similar combinations) are fired when exposed to a small, defined flame. A test method for measuring propagation times 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 6941 standard is one of two closely related test methods for the flammability of textile fabrics. These two test methods are:

• The test method defined in the ISO 4880 standard determines the ease of ignition.
• The test method defined in the ISO 6940 standard determines the flammability.

The test methods defined in the EN ISO 6940 and 6941 standards are widely applied throughout the industry, especially in the textile and apparel manufacturing sectors, where they are widely used for testing fabrics and other woven material products.

Tests conducted within the framework of the EN ISO 6941 standard are performed either on surface exposure or edge exposure or both. The vertical flammability index is calculated on the basis of the measured burning times.

For each exposure condition, at least six samples of the product are tested, three cut longitudinally and three crosswise. 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.

Among the numerous test, measurement, analysis and evaluation studies it provides for businesses in various sectors, our company also provides services for the measurement of the flame propagation properties of vertically oriented samples for the combustion behavior of textile fabrics within the scope of EN ISO 6941 standard, with its trained and expert staff and advanced technological equipment. gives.
