This method determines the bursting strength of knitted and other non-woven fabrics by the diaphragm pressure procedure. Althrough it may also be used with woven fabrics, it should be noted that for such matarials 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.

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 existing applicable regulatory requirements prior to its use.
