5.1 This test method allows for the measurement of the torque retention properties of container/continuous thread closure systems of various designs, materials, and manufacture, and is suitable for packaging development and engineering evaluation.5.2 This test method can be used for the evaluation of container/continuous thread closure systems under controlled conditions (where the application torque is known and the applied downward force to the closure is zero).5.3 This test method measures torque retention properties of container/continuous thread closure systems with the use of a non-automated, spring torque-meter (with either a dial indicator or a digital readout) or a torque wrench.1.1 These test methods evaluate the torque retention of continuous thread closures on containers, with matching finishes, for predetermined environmental conditions over time.1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.NOTE 1: The SI unit system is the recommended system.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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

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.

Conventional rubber aging tests that are normally carried out on unstretched test specimens are of limited use in assessing the life of rubber threads since these are usually kept extended in use.1.1 This test method covers the extent of deterioration of rubber threads by measuring the reduction in physical properties when a thread is maintained at a constant elongation under conditions more severe than those encountered in service. This test method is a comparative indication only; it may not be possible to correlate the results with the actual duration of life in service.1.2 The values stated in SI units are to be regarded as the standard. The values in parentheses are for information only.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.
