4、The type of environmental testing:
Currently, many countries have standardized the environmental test, and have also developed similar environmental test standards, which mainly include the following environmental test items:
(1) low-pressure (high altitude) test:
The test applies to air transport in the cargo hold of the aircraft weapons, weapons used on the plateau, and air-transported weapons in the aircraft injury occurs after the rapid decline in pressure. The purpose of the test is to examine the performance of the weapon in a low-pressure environment and the impact of rapid pressure drop on the performance of the weapon. Simulation of the highest altitude up to 30000m (m), the test to take the height of the corresponding temperature value.
(2) High-temperature test:
The test weapon is in high-temperature air, but not subject to direct sunlight. Test for the hot season in an indoor or confined space or close to the engine and other sources of heat storage or use of weapons. We conduct the test only when we cannot verify the effects of high temperatures using the solar radiation test. The purpose of the test is to examine the performance of the weapon when stored or used in a high-temperature environment.
(3) Low-temperature test:
Specimens likely to be used in a low-temperature environment during their life cycle undergo the test. The test aims to determine if the specimen can withstand storage, manipulation, control, and operation in a long-term low-temperature environment.
(4) Thermal Shock Test:
The test applies to weapons that are routinely subjected to very rapid temperature changes in a predetermined area or mode of use. Bombers place bombs in electronic equipment bays, missiles, electro-optical equipment, and bomb bays on aircraft that take off from desert airports and ascend to high altitudes; they airdrop weapons from high altitudes into desert areas, and they transfer weapons from indoors to outdoors in the Arctic. Currently, we only conduct airborne thermal shock tests, and in the future, we will be able to conduct thermal shock tests from air to water. The purpose of the thermal shock test is to examine the effect of sudden changes in ambient temperature on the performance of the weapon.
(5) Solar radiation (sunshine) test:
This is a test on 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 sunlight test examines the effects of solar radiation on the use or open storage of weapons or related materials.
(6) Rain test:
The test applies to the use of the process and may be subject to rain weapons. The rain test includes no wind when the rain test and wind when the rain test. The purpose of the rain test is to test the waterproof performance of the rain protection equipment and test the performance of the weapon during and after the rain.
(7) Moisture test:
Armaments must undergo testing for use in a warm and humid environment. Tropical areas throughout the year, the mid-latitude regions of the year with varying lengths of the season are this warm and humid environment. The purpose of the test is to test the weapon’s ability to adapt to a warm and humid environment.
(8) Anti-mould test:
Warmth and humidity are the conditions for the growth of micro-organisms, which are widely found in the tropics and mid-latitudes. Design all standard general-purpose armaments and equipment to consider the issue of mold resistance. The purpose of the test is to assess the degree of mildew and mildew on the performance of the weapon or the use of the degree of impact.
(9) Salt spray test:
Salt is very widely distributed on Earth. The ocean, the atmosphere, the ground, lake water, and rivers have salt, especially in the coastal areas of salt content is relatively large, and the ocean contains the largest amount of salt. No weapon does not come into contact with salt. Therefore, all weapons are in some form of salt environment during their life cycle. The purpose of the salt spray test is to examine the effect of a salty, humid atmosphere on the performance of the weapon, in particular the performance of the coated protective layer and the compatibility of the materials.
(10) Sand and dust test:
The test applies to all mechanical, electrical, electronic, and electrochemical armaments used in dry sand or air with a relatively high dust content. The test divides into a dust test and a sand test. The dust test uses dust and fine sand, which can get into crevices, cracks, bearings, and joints. The sand test uses sand particles of 149 to 850 μm (microns), which are large, sharp particles that can have an erosive and clogging effect, reducing the effectiveness, reliability, and serviceability of the equipment. The sand and dust test assesses the weapon’s capability for use and storage in a sandy and dusty environment.
(11)Immersion test:
Immersion test includes immersion, drip, and pressurized water test. The immersion test applies to equipment requiring watertightness and to equipment used wholly or partially submerged in water. In some cases, instead of the rain test, people may use this test to verify watertightness. The purpose of the test is to examine the ability of the weapon to remain watertight when immersed in water.
(12) Freezing rain test:
The test applies to equipment that will encounter freezing rain during normal use. The purpose of the test is to examine the effect of rain, fog, and splashing seawater on the performance of the equipment after it freezes, but also for the evaluation of de-icing devices and techniques.
