1. PURPOSE AND SCOPE 1.1 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. 1.2 The method is particularly applicable to apparel and furnishing fabrics¹
but is not intended for use on heavy industrial fabrics. 1.3 The method specifies two seams, one intended for use with apparel fabrics
and the other for use with furnishing fabrics. 1.4 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. 1.5 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. ¹ "Furnishing" includes upholstery, drapes and bedspreads.
