GB/T 29365-2012Wood-Plastic Composite (WPC) - Test methods of artificial weathering (English PDF)

3.1 WPC wood-plasticcomposite

In thermoplastics, or other lignocellulosic biomass fiber as the main raw material, molding made of composite materials.

3.2 Artificial weathering

The sample was placed under artificial conditions, simulation and strengthen the natural environment of light, heat, air, temperature, humidity, rainfall and other factors, the occurrence of sample

Phenomenon accelerated destruction.

4.1 Xenon

4.1.1

should be consistent with the provisions of GB/T 16422.1 and GB/T 16422.2 of.

4.1.2

xenon lamp and the filter during use will gradually aging, the deposition of scale, sample contamination can lead to decreased radiation intensity should be regularly feed

Row of light energy monitoring. In measuring the energy of light, the light sensor should be fixed in the sample received the same light energy position when the measured light energy does not match

When combined test requirements, xenon lamp power should be adjusted, if necessary, clean the xenon lamp and filter. Xenon lights and filters, should be based on the use of vendor-supplied

The timely replacement of life. Unless otherwise noted, is usually used to monitor the sample either narrow band, but also to monitor broadband radiation energy band radiometer

As the light energy monitoring equipment.

4.2 Fluorescent UV lamps

Shall comply with the provisions of GB/T 16422.1 and GB/T 16422.3 of.
