This method is for evaluating the resistance to slippage of weft yarns on warp yarns, or warp yarns on weft yarns, at the seam of a woven fabric.

The method is particularly applicable to apparel and furnishing fabrics ("Furnishing" includes upholstery, drapes and bedspreads.) but is not intended for use on heavy industrial fabrics.

The method specifies two seams, one intended for use with apparel fabrics and the other for use with furnishing fabrics.

Resistance to seam slippage is the force per 25 mm width of seamed specimen required to produce elongations of 3 and 6 mm respectively, in excess of the elongation of the fabric under the same force.

The testing and evaluation of a product against this method may require the use of materials and/or equipment that could be hazardous. This document does not purport to address all the safety aspects associated with its use. Anyone using this method has the responsibility to consult the appropriate authorities and to establish appropriate health and safety practices in conjunction with any applicable regulatory requirements prior to its use.
