Crimp Joint Testing
Crimp Joint Testing
Crimp joint testing measures the tension force required to pull apart or separate the components of a wire crimp, in most cases connected to a terminal or to another wire. The reliability of a multitude of products depends critically upon the this particular type of fastener.
Benefits of Crimp Joint Testing
These include:
- Ensuring crimp joints are fit-for-purpose
- Ensuring the safety and quality of products
- Reducing material costs and achieving lean manufacturing goals
- Compliance with industry standards
Standards
A number of national, international and military standards have been developed for testing crimp joints including:
- ASTM B913
- BS 5G 178 (Part 1)
- DEF STAN 59-71
- ISO 1966:1973
- MIL-C-39029, MIL-DTL-22520G, MIL-T-7928
- NASA-STD-8739-4
- SAE/AS7928
- UL486A
Such standards have generic similarities, each one defining a specific tensile load per cable gauge, which the crimp joint must be able to sustain without failure.
