Nowadays product function and appearance are no longer the sole focus. Quality and reliability are increasingly valued by markets and customers. Through using various of environmental experimental equipment to simulate climate conditions--high temperature, low temperature, high temperature and humidity and temperature changes, to accelerate the possibility of failure in usage environment, so as to verify whether the quality is at the expectation in research, design, and manufacture process. In this way reliability test can evaluate the overall product to guarantee the product reliability of life period.
Temperature humidity
Temperature and humidity test are applicable to products that may be used in warm and humid environments.
As for plastic materials, PCB,PCBA, porous materials or nished products ect, a variety of different materials would have different forms of physical reaction in different temperature and moisture condition, mostly temperature would cause plastic deformation, which would result in the poor start of the product in the over-temperature or low temperature.
Capillary effect can induce the surface of porous materials appear moisture adsorption,inltration, condensation, etc, in the humidity environment, electrostatic charge accumulation effect can induced product failure in the low-temperature environment.
Photo Aging Test
The painting, plastic and other polymer materials often occurs the phenomenon like pulverization, discoloration, blistering, cracking, be off the surface etc, which would seriously affect their functions of the mechanical performance and appearance.
So researching the light aging mechanism of polymer materials is needed for us to nd the suitable articial aging test, which can approach to objectively simulate the natural conditions of material usage and to provide rapid detection and evaluation for the development and application of materials.
The common test methods are mainly carbon arc lamp , xenon lamp , uorescent UV lamp (QUV), metal halide lamps etc.
Xenon-Arc Weathering
Xenon test is the destruction of the effect of simulated full spectrum sunlight with a xenon lamp, it used to simulate the spray rain , dew, exposure, dark effect to observe the change of the material in the sunlight under different conditions.
Carbon Arc Lamp Test
Carbon arc lamp is a relatively old technology, carbon arc instrument was rst used by chemists to assess the light fastness of dyed textiles (widely used to the blue wool standard).
Because of the project technology of long history, the rst articial light aging technology is the use of the equipment, so it can see this method in the earlier standard , especially often used as the light of articial aging test method in Japan in the early standard technology of carbon arc lamp .
UV Aging
UV aging testing machine does not simulate a full spectrum of the sun light, but simulate the damaging effects of sunlight.
To achieve by controlling the main radiation of uorescent tubes within ultraviolet band .
The ultraviolet uorescent lamp is used to simulate sunlight as well as the impact of moisture through condensation or spray. After the test, we will assess the changes of material in color, gloss, cracking, blistering, UV aging testing machine does not simulate a full spectrum of the sun light, but simulate the damaging effects of sunlight.

Metal Halide Lamp
Metal halide lamp is mainly suitable for UV ink, UV paint curing, dry lm, wet lm, green solder and plate exposure.
Corrosion Test
Corrosion test is a kind of material test to detect the chemical or physical (or mechanical) chemical damage process caused by the interaction between metal and other materials.
The corrosion test is an important means to control the corrosion mechanism and to control the corrosion process.
Common Salt Spray
The spraying device will change about 5% mass fraction of Sodium Chloride Solution salt fog, toperform the free settlement, the salt fog can uniformly fall on the surface of the sample, Common salt spray includes neutral salt fog, acid salt spray and copper accelerated salt spray.
Cyclic Salt Spray
The corrosion types of cyclic salt spray test include chemical corrosion and electrochemical corrosion due to the change of temperature and humidity.
The test is a multi cycle process, is the simulation of extreme weather conditions in the actual environment, especially in the hot damp heat environment and during water evaporation.
Salt deposition and the drying of sample surface will lead to higher salt concentration and the covering surface of corrosion rate. In addition, the process would also directly accelerated the corrosion reaction due to its surface contact with oxygen.
Gas Corrosion
Gas corrosion test can reproduce the damage degree of materials or products within a certain time by using sulfur dioxide, nitrogen dioxide, chlorine, hydrogen sulde and other gases at a certain temperature and relative humidity of the environment to accelerated corrosion damage of materials or products.
It is used to determine the corrosion resistance and the comparison of the quality of the similar protective layer of parts, electronic components, metal materials, electrical and electronic products, and industrial products in the mixed gas.
Condensate Test
Condensate test is an articial accelerated aging test by articially simulate hot and humid atmosphere in a closed testing box.
Its test method commonly is the static simulation, to keep the box in a stable temperature and high humidity atmosphere to maintain the continuous surface condensation process, which means there are continuous water droplets on the material surfaces during the test.
Mechanical Test (Vibration, Shock, Drop)
●Vibration test is a test to simulate a series of vibration phenomenon, test whether the product can withstand the vibration environment of transportation or use in the life cycle.
●Shock is a sudden, violent energy release, energy conversion and energy transfer, the impact of a short duration, the impact of a one-time process without a cyclical.
●Drop test is required in falling from a height to a test surface, confirm the product during handling due to rough handling by drop adaptability.
Three Comprehensive Test
Integrated environmental testing is a combination of two environmental stress factors, the role of the integrated environment can be more real, more realistic response to the performance of the products in the eld of use, more able to expose the defects of the product.
IP Protection
IP class test is mainly used for the assessment of shells' protection reliability of all kinds of electrical products and shell seals in the dust, moisture, water or diving and other harsh environment.
Its purpose is to verify the performance of products and component and to provide the corresponding protection of the human body at the same time because people will contact with hazardous components while using.
