1.1 This test method establishes the requirements for a standardized method of evaluating the quality of crimped-type electrical connections to solid or stranded conductors. This test method applies to 16-gauge and smaller diameter copper wire, coated or uncoated. 1.2 This test method is applicable to connection systems intended for indoor use, or for use in environmentally protected enclosures. Additional testing may be required to assure satisfactory performance in applications where high humidity or corrosive environment, or both, may be present. 1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this 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 become familiar with all hazards including those identified in the appropriate Safety Data Sheet (SDS) for this product/material as provided by the manufacturer, to establish appropriate safety, health, and environmental practices, and determine the applicability of regulatory limitations prior to use. 1.5 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. ====== Significance And Use ====== 5.1 This test method establishes the requirements for a standardized method of evaluating the performance of crimped-type electrical connections having solid or stranded conductors. 5.2 In order to achieve a successful crimped connection, the crimping tool must deform the material of the crimp barrel or barrel tab(s) around the conductor. As a consequence, the conductor surfaces are placed under compression by the crimp terminal and areas of contact are established between the conductor and the crimp barrel. These areas provide the desired electrical connection. A reliable crimped connection is one that is capable of maintaining the contact between the conductor and crimp barrel so that a stable electrical connection is maintained when it is exposed to the conditions it was designed to endure during its useful life. 5.3 Evaluation testing is designed to ensure that a particular design crimped connection system consisting of conductor and component and associated tooling is capable of achieving a reliable electrical and mechanical connection. After the evaluation is completed, if any change in the system parts is made, the system should be reevaluated using the same procedures. 5.4 After completion of the evaluation test, the tensile pull strength results may be used to develop acceptance requirements to be used in inspection of subsequent production lots of crimped connections. An example of such an acceptance requirement is shown in Appendix X1 . 5.5 The aging test, 33 days exposure at 118°C, has been used in the telecommunications industry to simulate 40 years of service at a moderately elevated temperature of 50°C, an environment that components experience within large banks of telephone equipment. This environment is similar to that seen in a wide range of electronic systems operating indoors containing active components that dissipate power. The test is designed to reproduce the stress relaxation of copper alloys in such service and has been used extensively in evaluating wire wrap connections. It also accelerates other thermally activated processes such as oxidation although their acceleration factors may be different from that of copper stress relaxation. 5.6 The aging test accelerates stress relaxation processes and other thermally activated processes but does not address some other possible hazards such as corrosion. Additional testing may be appropriate if the intended service environment presents such hazards.
