CAN/CGSB-4.2 No./N° 11.1-M88

Determines the bursting strength of knitted and other non-woven fabrics by the diaphragm pressure procedure. Although it may also be used with woven fabrics, it should be noted that for such materials it is the breaking strength of the less extensible set of yarns that governs the value of bursting strength observed. The extensibility of the diaphragm limits the use of this procedure to materials less extensible than the diaphragm itself.
