ASTM F1648-95(2008)
(Test Method)Standard Test Methods for Archery Bowstring Component-Serving String Material
Standard Test Methods for Archery Bowstring Component-Serving String Material
SIGNIFICANCE AND USE
These test methods are intended to provide basic information for evaluation and procurement for the user of serving string materials for bowstrings.
These test methods are not meant to be all inclusive since special circumstances may occur that dictate the use of nonconforming procedures for evaluation. These special circumstances and the requirements they establish cannot be totally anticipated and therefore must be considered on an individual basis.
SCOPE
1.1 These test methods cover the classification and testing of serving string as a component material used in the fashioning of archery bowstrings.
1.2 These test methods are not intended to provide information beyond any evaluation of the serving string material that would determine its fitness for use other than in the fabrication of the completed bowstring.
1.3 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.
