Standard Test Method for Resistance to Yarn Slippage at the Sewn Seam in Woven Upholstery Fabrics

Importancia y uso:

5.1 Test Method D4034 for measuring the resistance to fabric yarn slippage is considered satisfactory for acceptance testing of woven upholstery fabrics.

5.1.1 In case of disagreement arising from differences in values reported by the purchaser and the supplier when using this test method for acceptance testing, the statistical bias, if any, between the laboratory of the supplier and the laboratory of the purchaser should be determined with comparisons being based on the testing of specimens taken from a lot of material of the type evaluated to be as nearly homogeneous as possible and then randomly assigned in equal numbers to each of the laboratories.

5.2 This test method is intended to measure fabric yarn slippage at the sewn seam in upholstery fabrics under controlled conditions. This test method may not indicate actual field performance.

5.3 Fabrics that do not meet the requirements agreed upon between the purchaser and supplier should be classified as “delicate yarn slippage resistance” and the purchaser and furniture manufacturer so notified.
