ASTM F1752

4.1 This test method is intended to provide the user of cord materials for bowstrings the basic information for evaluation and procurement.

4.2 This test method is not meant to be all inclusive since special circumstances may occur that will dictate the use of nonconforming procedures for evaluation. Special circumstances and the requirements they establish cannot be anticipated totally and, therefore, must be considered on an individual basis.

TABLE 1 Cord Material Strength Requirements

^A Multiply by 4.448 for conversion to newtons.

1. Scope

1.1 This test method establishes the classification and testing of cord as a component material used in the fashioning of bowstrings.

1.2 This test method is not intended to provide information beyond any evaluation of the cord material that would determine its fitness for use other than in the fabrication of completed bowstrings.

This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
