What is an environmental simulation test? Environmental simulation test equipment is a method for enterprises or institutions to verify the quality of raw materials, semi-finished products and finished products under the conditions of simulating various environmental climates, transportation, handling, vibration, etc. The purpose is to verify whether materials and products achieve the expected quality goals in R&D, design, and manufacturing by using various environmental test equipment for testing. Widely used in colleges and universities, shipbuilding, electrical, electronics, medical, instrumentation, petroleum instrumentation, petrochemical, medical, automobile and motorcycle fields. The environmental simulation test equipment can perform high temperature, low temperature, temperature shock (gaseous and liquid), immersion, temperature cycle, low pressure, high and low temperature and low pressure, constant humidity and heat according to IEC, MIL, ISO, GB, GJB and other standards or user requirements. , Alternating damp heat, high pressure cooking, sand dust, explosion resistance, salt spray corrosion, gas corrosion, mold, rain, solar radiation, photoaging, etc.

The institutions that can conduct environmental simulation tests mainly include the Fifth Electronics Research Institute of the Ministry of Industry and Information Technology, the Environmental Reliability and Electromagnetic Compatibility Test Center, the Aerospace Environmental Reliability Test and Testing Center, and 301 units. (1) Low pressure test: The test is applicable to weapons transported by air in the cargo compartment of an aircraft, and weapons used on plateaus and air transported weapons experience a rapid drop in pressure after the aircraft is injured. The purpose of the test...

spaces or close to heat sources such as engines in high temperature seasons. This test should only be performed if the solar radiation test cannot examine the effect of high temperature. The purpose of the test is to verify the performance of storage or use in a high temperature environment. (3) Low temperature test: The test is suitable for specimens that are likely to be used in a low temperature environment during the life cycle. The purpose of the test is to test whether the test piece can be stored, manipulated, controlled and fought in a long-term low temperature environment. (4) Thermal...

from air into water. The purpose of thermal shock test is to examine the effect of sudden changes in ambient temperature on the performance of weapons. (5) Solar radiation (sunshine) test: This is a test for weapons and their manufacturing materials exposed to sunlight. Solar radiation can cause photochemical and thermal effects. In most cases, this test can replace the high temperature test. The effect of solar radiation on the use or open storage of weapons or related materials can be tested through the sunshine test. (6) Rain test: The test is applicable to weapons that may be exposed to rain...

mid-latitudes with seasons of varying lengths of the year. The purpose of the test is to test the weapon's ability to adapt to a warm and humid environment. (8) Anti-mildew test: Warm and humid conditions are conditions for the growth of microorganisms, which are widely found in tropical and mid-latitude regions. All standard general-purpose weapons and equipment should be designed with mildew resistance in mind. The purpose of the test is to assess the degree of mildew on the weapon and the degree of its influence on the performance or use of the weapon. (9) Salt spray test: Salt is widely distributed...

(10) Sand and dust test: The test is applicable to all mechanical, weapons used in dry sand or air with relatively high dust content. The test is divided into dust test and sand test. The fugitive dust test uses dust and fine sand, which can enter crevices, cracks, bearings and joints. The sand blowing test uses 149-850 μm (micron) sand particles. Large and sharp sand particles can cause erosion and blockage, reducing the effectiveness, reliability and maintainability of equipment. The purpose of the sand and dust test is to test the use and storage capabilities of weapons in a sand and dust...

will encounter freezing rain in normal use. The purpose of the test is to examine the effects of rain, fog and splashed sea water on the equipment's performance after freezing on the equipment, and to evaluate deicing devices and techniques.
