Scope:

This method determines the breaking strength of fabrics by the ravelled strip method. It is intended primarily for testing high-strength 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-M.

 

This method may be used to estimate the breaking strength of a given width of a fabric by testing narrower specimens of at least two different widths. 

 

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

 

The procedure may be used with constant-rate-of-extension (CRE) type (e.g., strain gauge) or constant-rate-of-traverse (CRT) type (e.g., pendulum) tensile testing machines.
