Textile test methods — Breaking strength of yarns — Single strand method
Scope:
This method determines the breaking strength of single strands of yarns, including monofilaments, single yarns, plied or folded yarns, cabled yarns, cords, threads and twines. It is designed primarily for testing yarn in package form but can be used for single strands removed from a fabric.
The method is applicable to testing yarns either in the conditioned state or when wet.
The method may be used with constant-rate-of-extension type (e.g., strain gauge), constant-rate-of-traverse type (e.g., pendulum), or constant-rate-of-loading type (e.g., inclined plan) testing machines.
Automatic yarn-testing machines may be used provided they can be operated under the conditions specified.
