This method determines the tearing strength of woven and nonwoven fabrics by the trapezoid procedure.

Two procedures for the calculation of tearing strength are given, one for woven fabrics and the other for nonwoven fabrics. The two procedures do not usually give the same result.

The testing and evaluation of a product against this method may require the use of materials and/or equipment that could be hazardous. This method 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. CGSB neither assumes nor accepts any responsibility for any injury or damage that may occur during or as the result of tests, wherever performed.
