Standard Test Methods for Rubber Thread (Withdrawn 2012)
For adequate service performance, rubber threads must be tested by appropriate test methods. This standard gives a number of test methods that are known to be important in rubber thread technology.
1.1 These test methods cover the testing of both round extruded latex and rectangular cut rubber thread products in which the base material used in manufacture may be natural rubber or synthetic rubber, alone or in combination. These tests are to be made only on the bare uncovered rubber thread.
1.2 Owing to the comparatively small cross section of the material and also because of the unusual conditions of service of this material, certain special test methods have been developed and take the place of the tests for other rubber products.
1.3 Comparisons may only be made on new rubber threads or those of identical processing histories. In the interpretation of results from threads which have been subjected to spooling, fabrication, or other process, the previous history is important, and what is known of this and any relaxation treatments used should be stated.
1.4 The test methods appear in the following sections:
1.5 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
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.
