3 Terms and Definitions
The following terms and definitions apply to this section.
3.1
Aside from sample to sample comparison of the surface state of the same batch of corrosion caused by sample physical and mechanical properties change.
3.2
When experimenting with new materials, improved technology or improved materials, original material with a known test data, sample production process for comparison test.
4 Test principle
4.1
Tracking sun exposure tests in outdoor atmosphere, rotation control system to increase exposure frame, with the rotation of solar tracking, full strengthening too
Effects of light and heat of solar radiation, exposure to accelerated aging rate of the sample surface.
4.2
Sun tracking energy concentrated accelerated exposure test in the outdoor atmosphere, through tracking systems and reflection systems control, sun
Reflected light is focused onto the surface of the sample area (target area), and strengthen the amount of solar radiation suffered a sample, and is equipped with blower system and artificial rainfall
Sprinkler system, to accelerate the aging speed of the target area of the sample.
