Engineering insight
Use the following as an early selection reference. Specific models, datasheets and samples should be confirmed with actual structure drawings.
01
Mechanical test items
Mechanical reliability is the connector's first line of defense. Key tests include mating cycle durability (IEC 60512-5), terminal retention (EIA-364-29), vibration (IEC 60068-2-6), shock (IEC 60068-2-27) and flexure (EIA-364-41). Test conditions and criteria vary by application domain.
02
Environmental adaptability testing
Environmental tests verify connector stability under extreme conditions. Core items include thermal cycling (IEC 60068-2-14), damp heat storage (IEC 60068-2-78), salt spray (IEC 60068-2-52), mixed gas (IEC 60068-2-60) and thermal shock (IEC 60068-2-14). Automotive-grade connectors must also meet USCAR-2 additional requirements.
03
How to select test matrix by application
Not all connectors need full testing. Indoor office devices only need basic mating cycle and thermal cycling; outdoor base stations must do salt spray + UV aging; automotive needs USCAR-2 complete matrix (including LV214); medical devices need biocompatibility testing. Identify applicable industry standards early to tailor the test plan.
