1. Purpose of vibration test:

Reference test standards: GMW3172 6.6.2, gmw3431 4.3.12, gm9123p 9.4, gme3191 4.26

2. Purpose of composite environmental test (three synthesis):

Its main function is to use the specific environmental stress lower than the design strength of the product to expose the potential defects of the product in advance and eliminate them, so as to avoid failure due to the existence of such defects during normal use.

Reference test standards:

GMW3172 4.2.8/5.5.3/5.5.4, GMW3431 4.4.10, GM9123P 10.2.2, IEC60068-2-13/40/41, GB2423.21/22/25/26, SAEJ1455, MIL-STD-202G Method 105C, MIL-STD-883E Method 1001, MIL-STD-810F Method 500.4, GJB150.2.

3. Purpose of mechanical impact test:

During the life cycle of the product, there are two situations in which the product will be impacted. One is the impact caused by the collision and jumping of the vehicle when walking on the steep road or the impact caused by the falling of the personnel when carrying.

Reference test standards: GMW3172 5.4.2, gmw3431 4.3.11, gm9123p 9.2, vw80101 4.2, ETL_ 82517 8.2.2, MGRES6221001 9.4.2, SES E 001-04 6.13.1, FORD DS000005 10.8.20, FORD_ WDS00.00EA_ D11 4.6.3, PSA B21 7090 5.4.5, IEC60068-2-27, GB2423.5/6, GJB150.18, EIA-264, SAEJ1455, MIL-STD-202G Method 213B, MIL-STD-810F Method 516.5

4. Purpose of temperature test:

The temperature test is used to obtain data to evaluate the impact of temperature on equipment safety and performance, such as hardening of materials, deformation of parts due to different shrinkage characteristics, change of resistance and capacitance functions, shortening of service life, loss of viscosity of lubricants, etc.

Reference test standards:

BMW GS95003-4, VW80101 5.2.1, PSA B21 7090 6.6.5, JESD-22A104C, IEC60068-2-14, MIL-STD-810F, MIL-STD 883E 1010.7, GB2324.22(air to air), GJB150.5, JESD 22-A104C Ag

5. Purpose of salt spray test: salt spray test is proposed to be used as a laboratory to accelerate salt spray corrosion so as to simulate the impact of products used by the sea or transported by sea.

Reference test standards:
