Abrasion resistance EN 530 Method 2

Abrasion is the physical destruction of fibers, yarns, fabrics resulting from the rubbing of the textile suface over an abrasive glass paper. It ultimately affects the appearance of the fabric and results in the loss of performance properties after a number of cycles.

Flex cracking resistance EN ISO 7854 Method B Flex cracking simulates repeated flex and folds in the fabric. The number of cycles to failure indicated by cracks and holes is recorded.

Tear resistance EN ISO 9073-3 Tear resistance determines the trapezoid tear resistance of a nonwovens by applying a continuously increasing extension in such a way that a tear propagates across the width.

Tensile strength EN ISO 13934-1 Tensile strength determines the maximum force and elongation at maximum force of the fabric using a strip method. The fabric is extended at a constant rate until it ruptures.

Puncture resistance EN 863 Puncture records the maximum force required to push a spike through the fabric with a constant rate until it perforates.

Seam strength EN ISO 13935-2 Seam strength determines the maximum force of sewn seams when the force is applied perpendicularly to the seam which is extended until it ruptures.

MANDATORY TESTS A CE marking signifi es that chemical protective clothing meets certain minimum requirements (please see Annexe 1). However, it does not mean that chemical suits of the same Type offer the same level of protection performance. This is why it is essential to look at the results of the tests carried out on the material used to make the garment.

As part of the CE requirements a number of mandatory fabric tests are required and, for each Type, these are classifi ed from Class 1 (lowest) to Class 6 (highest). For further information please see Annexe 2.

The following are the mandatory tests for mechanical performance that must be carried out on a fabric: T
