Significance and Use | |||||||||||||||||||||
7.1 This test method is designed to provide data for the control and specification of materials and for characterization purposes in research and development of new materials. It is possible that the tensile properties will vary with the size of specimens and the speed of testing. Consequently, these factors along with others noted herein must be controlled where precise comparative results are desired. |

1. Scope | |||||||||||||||||||||
1.1 These test methods cover the procedures for testing rigid round rods used in electrical insulation. These round rods include many types made from fibrous sheets of basic materials, such as cellulose, glass, or nylon in the form of paper, woven fabrics, or mats, bonded together by natural or synthetic resins, or by adhesives. Such round rods include vulcanized fiber and thermosetting laminates as well as round rods made from cast, molded, or extruded natural or synthetic resins, with or without fillers or reinforcing materials. 1.2 The procedures appear in the following sections:
1.3 The values stated in inch-pound units are to be regarded as the standard. 1.4 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.
