Full Description

This method determines the breaking strength of nonwoven textile fabrics. It is intended primarily for testing materials that are difficult to grip in the clamps of the testing machine and that cannot be tested satisfactorily by CAN/CGSB-4.2 No. 9.1 or 9.2. (This test method is recommended for determining breaking strength of nonwoven textiles greater than 200 g/m^2 in mass, as an alternative to CAN/CGSB-4.2 Nos. 9.1 and 9.2 where jaw breaks may be a problem.)

The procedure is applicable to fabric either in the conditioned state or wet.

The procedure is recommended particularly for use with a constant-rate-of-extension tensile testing machine (e.g., strain gauge). (This method was developed for use on CRE type machines and the validity of the test results, if a CRT type machine were used, is not known.)

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.
