Annotation

PURPOSE AND SOCPE

This method determines the breaking strength of fabrics by the raveled 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 (Note1).

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.

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.
