This part of the standard will be applicable to the determination of the inspection interval to breakdown of specimens covering all textile fabrics including nonwovens apart from fabrics where the specifier indicates the end performance as having a low abrasion wear life. The breakdown point which is reached: - in woven fabrics, when two separate threads are completely broken; - in knitted fabrics, when one thread is broken causing a hole to appear; - in pile fabrics, when the pile is fully worn off; - in nonwovens, when the first hole resulting from the wear is of a diameter at least equal to 0,5 mm.
