1.piastic part: smooth and fiat surface without discolor, broken, cark, distortion defects is acceptable.
2.Metal part: bright and even surface without rust, oxide, fog and obvious physical damage defects is acceptable.
3.Wire:Clearing surface without discolor , broken defects is acceptable.
4. The contact crimp, identification, other component shall be checked against the relevant specification.

Dimension

Calipers, ruler, tape measure

Use caliper, ruler or tape measure to measure the dimension

The dimension accord with the part drawing

Insulation resistance

Megohmeter or insulation resistance tester

Apply requirement voltage (desiccation bound:500V DC: damp bound:100V DC) between all contacts connected together and a metal foil surrounding the housing. In addition, apply the voltage a different test sample to every two adjacent contacts

Insulation resistance:
≥500 MΩmin;

Withstand voltage

Withstand voltage tester

Apply an ac voltage of 500V (50Hz) f or 1min across all contacts connected together and a metal foil surrounding the housing . In addition, apply the voltage a different test sample to every two adjacent contacts.

During this test, neither dielectric breakdown nor flash-over shall occur.

Pull out force

Force tester

Mount the contact in a fixture. Apply an axial force at axial between 25 and 100mm/min.For double, triple or multiple crimp setups with conductor sizes within one step, pull the largest conductor

High temperature testing

Temperature chamber capable of maintaining the specified temperature conditions

Place the test sample in a test chamber and leave them there at the temperature105℃±2℃for 8 h. The sample shall be allowed to cool in air for 24 h.

After test, meet the item 4.1, 4.4, 4.5 requirements.

Low temperature testing

Temperature chamber capable of maintaining the specified temperature conditions

Place the test sample in a test chamber and leave them there at the temperature-40℃±2℃for 8 h. The sample shall be allowed to cool in air for 24 h.

After test, meet the item 4.1 requirement.

Humidity heat, Constant

Temperature-Humidity
chamber capable of maintaining the specified condition on a continuous basis

Place the test samples in the chamber(shall not match the contact pair ).Raise the temperature to the (40±2）℃,During the temperature transition ,the humidity to（90±3）% within 1 h. Hold the test samples to（40±2）℃at（90±3）% RH for 96h. The sample shall be allowed to cool in air for 1h.

After test, meet the item 4.1,4.4,4.5
Requirements.

Salt spray

Salt spray chamber

The salt solution concentration shall be 5% solution shall be prepared by dissolving 5±1 part by weight of salt in 95 parts by weight of distilled or other water. Apply it to mated connectors fitted with the full complement of contacts and cables connected. The duration of the test shall be 24h. The PH shall be maintained between 6.5 and 7.2. The test shall be conducted with a temperature in the exposure zone that is maintained at(35±2)℃. Salt deposits shall be removed by a gentle wash or a dip in running water and a light brushing. The sample shall resume at room temperature for 1~2h.

Visual examination
The following appearance appearance shall not be allowed:
Exposure of base metals, pitting and porosity of finishes. Cracking and delaminating of components or finishes, or both
