Textile test methods — Breaking strength of fabrics — Strip method — Constant-time-to-break principle
Scope:
This method determines the breaking strength of fabrics by the ravelled strip method. The method is also applicable to narrow fabrics. It is not recommended for knitted fabrics and may have to be modified for certain woven fabrics containing high-stretch yarns.
The procedure is applicable to fabrics either in the conditioned state or when wet. It is particularly suited to the determination of change in breaking strength due to wetting.
The procedure may be used with constant-rate-of-extension type (e.g., strain gauge) or constant-rate-of-traverse type (e.g., pendulum) tensile testing machines.
