The reliability test is to expose the product under the environment of natural or artificial environmental conditions, to evaluate the performance of the product under the environmental conditions of actual use, transportation, and storage, and analyze the impact and mechanism of environmental factors and its mechanisms of environmental factors.
Construction material reliability test items include:
1. Climate and environmental test
1) Temperature aging test (high temperature aging, low temperature aging, temperature circulation test, temperature impact, constant temperature and humidity, three comprehensive tests)
2) Light aging test (aging lamp, ultraviolet aging, solar radiation, carbon arc light aging)
3) Shell protection level (rainstorm test, waterproof test, dustproof test, sand dust test, gravel test)
4) Corrosion environment test: gas corrosion test (sulfur dioxide, hydrogen sulfide, nitrogen dioxide, chlorine gas), salt fog corrosion test (neutral salt fog, acid salt fog, copper ion acceleration acid salt fog), solvent -resistant test (acid resistance test test , alkali resistance, alcohol -resistant, toluene, etc.)
5) Ozone aging
2. Mechanical Environment Test
Vibration test, mechanical impact test, stretching strength, compression strength, bending strength, falling test, shear strength, pencil hardness, Loos hardness, Shaw's hardness, tearing strength, and anti -folding strength, wear test, etc.
3. Comprehensive environmental test
Temperature+humidity+vibration comprehensive test, high temperature+vibration, low temperature+vibration, high and low temperature stretch test, high and low temperature bending test, high and low temperature impact test
4. Electrical performance test
The rated voltage, current, active power, powerless power, resistance, capacitance, inductance, conductivity, resistivity, surface resistance, volume resistance, medium loss factor and relative capacitance rate, breakdown voltage and electrical strength
