environmental and reliability test

environmental and reliability testing is to ensure that a product maintains functional reliability during its defined life, under the environment in which it is expected to be used, transported or stored. it exposes the product to the natural or artificial environmental conditions to undergo its action, in order to evaluate the performance of the product in the actual use, transportation and storage of environmental conditions, is one of the important quality characteristics of the product. generally, environmental reliability test is divided into mechanical environmental test, climate environmental test and comprehensive environmental test. mechanical environment tests mainly include mechanical vibration, mechanical impact, drop, collision and other tests. climatic environment tests include temperature test, temperature/humidity test, air pressure test, water test, salt spray test, sand dust test, gas corrosion test, etc. comprehensive environmental test mainly includes temperature and pressure comprehensive test, temperature and vibration comprehensive test, temperature and humidity vibration comprehensive test, temperature and pressure and humidity comprehensive test, etc.

q&a

what is the difference between uv lamp and xenon-arc lamp exposure ageing test?

the spectral distribution of fluorescent uv lamp can only simulate the uv part of sunlight, while the xenon-arc lamp simulates the spectral distribution of the whole sunlight. xenon- arc lamp has strong radiation in the 1000nm-1200nm wavelength infrared region, which will generate a lot of heat. moreover, because the energy of uv part of xenon-arc lamp increases less than that of uv lamp, the acceleration rate is relatively low. the simulation of fluorescent uv lamp is poor, but because of its high acceleration rate, by selecting the appropriate type of lamp can achieve the rapid screening of specific materials.

what metals is the salt mist test applied to?

neutral salt mist test is suitable for metal and its alloy, metal coating, organic coating, anodic oxidation film. acetate salt mist test and copper accelerated acetate salt mist test are suitable for copper nickel chromium or nickel chromium decorative coatings and also for aluminum anodizing film.

what is the purpose of vibration test?

the purpose of vibration test is to simulate a series of vibration phenomena. test the product in the life cycle, whether can withstand the vibration environment of transportation or use process, also can determine the product design and function requirements. the purpose of vibration test is to confirm the reliability of the product and to screen out the defective products before leaving the factory in advance, and to evaluate the failure analysis of the defective products so that they become high level and high reliability products.

ip代what is the meaning of the waterproof protection number in the ip code?

ipx0: non-protected;

ipx1: protected against vertically falling water drops;

ipx2: protected against vertically falling water drops when enclosure tilted up to 15°;

ipx3: protected against spraying water;

ipx4: protected against splashing water;

ipx5: protected against water jets;

ipx6: protected against powerful water jets;

ipx7: protected against the effects of temporary immersion in water;

ipx8: protected against the effects of continuous immersion in water;

ipx9: protected against high pressure and temperature water jets.
