High and low temperature testing

1.High temperature testing: The purpose of high pass testing is to determine the ability of components, equipment, or other products to be used, 

transported, or stored in high temperature environments. Test standard reference: G8T2423.2, IEC60068-2-2, IEIA364, MIL-STD-810F Common test 

parameters:+55T>-2LC, duration 4H (minimum)

2. Low temperature testing: The purpose of low temperature testing is to determine the storage adaptability of military and civilian equipment under

 low temperature conditions. Reference standard: IEC60068-2-1 (GB/T2423.1) ELA634, MIL-STD-810F Common tests mostly: -10C+-3C: Duration 4H 

(minimum) Simulated use in severe cold areas: -40C, Duration 4H (minimum)

Salt spray detection

1.Corrosion caused by salt spray: Corrosion is the damage or deterioration of materials under the influence of the environment. Most of the corrosion

caused occurs in the atmospheric environment, which contains corrosive components and factors such as oxygen, temperature, temperature changes, 

and pollutants. Salt spray corrosion is a common and most destructive form of atmospheric corrosion. The salt spray referred to here refers to the 

atmosphere of chloride, and its main corrosive component is the chloride salt in the ocean - sodium chloride It mainly comes from the ocean and inland 

saline alkali land.

Damp heat detection

1. Damp heat testing includes constant humidity heat testing and alternating humidity heat testing.

1）.Constant humidity and heat: The purpose is to determine whether electrical and electronic products, components, or equipment are exposed to high humidity

Adaptability during use, storage, and transportation under certain conditions.

Explanation of alternating humidity and heat test: The high and low temperature alternating humidity and heat test is used in aviation, automotive, and household 

2）.appliances Essential testing projects in scientific research and other fields, used to test and determine electrical, electronic, and Other products and materials 

subjected to high temperature, low humidity, alternating humidity and heat or constant testing Parameters and performance after temperature environment changes.

The temperature is controlled between 20 ° C-85 ° C, the humidity is controlled between 30% -98%, and the size does not exceed 1 meter square.

UV aging detection

UV aging testing can reproduce the damage caused by sunlight, rain, and dew

1. Product specifications: mainly used in automobiles, coatings, paints, printing and packaging, pigments, textiles, roofing materials, rubber, plastics, coatings, etc

2. Test standard: ISO 4892.3-2006; G B / T16422.3-1997；ASTM G 154-2006；ASTM D4674-2002.

3. Result determination: Visual inspection, color difference, grayscale, performance changes, etc

Xenon lamp aging test

The xenon lamp aging test simulates the destructive effect of full spectrum sunlight using xenon lamps. Using spray to simulate the effects of rain, dew, sun exposure, and darkness.

1. Application scope: mainly used in automobiles, coatings, paints, printing and packaging, pigments, textiles, roof materials, rubber, plastics, coatings, etc

2. Test standard: IS0 4892.2-2006; G B / T 16422 2-1999 ；ASTMG 155 - 2005 ；ASTM D 4459-2006.

3. Result determination: Visual inspection (visual inspection, color difference, grayscale, performance changes, etc.)
