Wire Tensile Testing Setup

Applications that use wire with a required connection strength need to be tested to guarantee a safe a reliable product. Determining how to test your wire connection and what equipment to use is an important part of the testing process. There are a few important considerations that must be made before testing. What are the wire connection strength requirements that must be met? What are the standards that need to be followed for your customers or industry? Are there recommendations from the manufacturers of the lugs, crimps or solder connections? From your experience, what particular problems should be addressed during testing? In general, wire connection lug testing can be broken into two categories; destructive pull testing and non-destructive pull testing. These tests both aim to determine a tensile force that the test wire can withstand. To meet the requirements of specific standard specifications, the tensile force that a wire can withstand must be greater than the minimum tensile strength defined by the standard. For your convenience, TestResources has compiled a list of ASTM, Automotive and Aerospace standards that apply to tensile testing of lugs. These standards apply to pull testing wire, pull testing lugs, and pull testing electrical connections. Also included are TestResources grips for lug testing, grips for tensile testing, and grips for pull testing crimps and machines for wire testing. TestResources universal material testing machines are effectively used for determining the strength of wire connections. TestResources test machines meet the requirements specified in many standard test procedures for constant-rate-of-extension and constant-rate-of-load machines. This allows the machines to be programmed to perform many unique testing procedures. Load cells are fitted to specific load applications to ensure the highest resolution of tests.
