Reliability testing is generally carried out in the product development and production stage, is the product reliability investigation, analysis and evaluation of a means. The test results can provide a basis for failure analysis, the study of corrective measures taken, to determine whether the product meets the target requirements.
Reliability test items:
Climatic environment (temperature and humidity): high temperature, low temperature, constant humidity and heat, alternating humidity and heat, temperature and humidity combination cycle, rapid temperature change, cold and hot shock, low pressure (height simulation)
Climatic environment (light): UV ultraviolet test, xenon lamp test, metal halide lamps, carbon arc lamp.
Mechanical environment: random vibration test, sinusoidal vibration test, *** vibration search and dwell, sinusoidal + random vibration test, random + random vibration test, mechanical shock test, collision test, steady state acceleration, drop test.
Integrated environment: temperature + temperature + vibration, temperature + temperature + shock, temperature + degree + collision, HALT / HASS / HASA, temperature + temperature + stacking, high-pressure cooking
Protection level: IP protection (waterproof, dust-proof), IK protection (protection against external mechanical collision)
Biological and chemically active substances environment: salt spray test, mold test, gas corrosion, chemical reagent resistance, artificial sweat
Physical properties: chemical reagent resistance, adhesion/abrasion/scratch resistance, hardness, tensile/compressive/yield strength, bending/rocking insertion/torque, drop ball impact/pendulum impact/impact hammer impact, color fastness/color difference, melt index/melting point, barrel drop/directional drop
