3.IT/AV reliability testing:

Reliability test:

          IT/AV products to provide climate, environment, machinery, life, failure analysis and other aspects to provide comprehensive, professional solutions, to provide customers with comprehensive product reliability testing and verification services, to ensure that the quality of customer products in line with the world's standards.

Environmental testing:

          Environmental test is to simulate real environmental conditions or reproduce the influence of environmental conditions to prove to a certain extent that the product remains intact and works normally under specific environmental conditions.Of products mainly include: the influence of thermal aging, softening melting sublimation, expansion, embrittlement, reduction, physical contraction of mechanical strength, moisture absorption or adsorption, chemical reaction, corrosion, increasing the conductivity of the insulation, resulting in cracking products, insulation damage, physical damage, mechanical failure, increasing the mechanical stress and so on.

The following items are involved:

Cold test GB/T 2423.1 IEC 60068-2-1 EN 60068-2-1IEC 60068-2-2 EN 60068-2-2Constant heat and humidity (constant temperature and humidity) GB/T 2423.3 IEC 60068-2-78 EN 60068-2-78Alternating damp heat GB/T 2423.4 IEC 60068-2-30 EN 60068-2-30Temperature change (rapid temperature change) GB/T 2423.22 IEC 60068-2-14 EN 60068-2-14Temperature/humidity combined cycle test GB/T 2423.34 IEC 60068-2-38 EN 60068-2-38

Climatic test:

Climate test means for the whole machine, electrical and electronic components or materials to provide a kind of artificial simulation of climate conditions or accelerated test, to evaluate the actual use of climate impact on product or material performance expectations, the purpose is to expose the product on components selection, structure design, and the shortcomings of the process, to improve climate adaptation ability of the products.

The following items are involved:

Salt spray test (alternating salt spray) GB/T 2423.17 IEC 60068-2-11 EN 60068-2-11GB/T 2423.18 IEC 60068-2-52 EN 60068-2-52GB/T 10125 ISO 9227 ASTM B 117IP protection test (IP code) GB 4208 IEC 60529 EN 60529UV test GB/T 16422.3 ISO 4892.3 ASTM G 154 ASTM D 4674Xenon lamp test GB/T 16422.2 ISO 4892.2 ASTM G 155...Artificial sweat test ISO 3160-2

Mechanical test:

          Mechanical testing is an effective method to evaluate the resistance of components, components and complete machines to mechanical stress in the expected storage, transportation and use environment.The main influences on the products are as follows: structural damage (such as structural deformation, product crack or fracture), product function failure (such as poor contact, misoperation of relay), technological damage (such as loosening of screws or connectors, unwelding), etc.

The following items are involved:

Vibration test GB/T 2423.10 IEC 60068-2-6 EN 60068-2-6GB/T 2423.56 IEC 60068-2-64 EN 60068-2-64GB/T 4857.7 ISO 2247...Impact test GB/T 2423.5 IEC 60068-2-27 EN 60068-2-27Collision test GB/T 2423.6 IEC 60068-2-27 EN 60068-2-27Drop test GB/T 2423.8 GB/T 4857.5 ISO 2248IK protection (hammer test) GB/T 20138 IEC 62262 GB/T 2423.55IEC 60068-2-75

Aging life test:

Aging life test is for electronic product simulation is a kind of high temperature or bad environment, or repeated testing, is one of the important test, improve product stability, reliability, is the production enterprise important production process to improve product quality and the competitive, through this test to check out the bad product or bad thing, nor is a customer provide effective means to quickly find and solve problems, to fully improve customer production efficiency and product quality.

The following items are involved:

Mean time between failures (MTBF) GB/T 5080.7 GB/T 13426 SJ/T 11325Wire sway test EIA-364-41Interpolation force test EIA-364-13Durability test EIA-364-09
