1 Scope

This standard specifies the test methods for artificial weathering WPC. This standard applies to WPC in xenon lamps and fluorescent UV lamp as the light source of artificial weathering aging test conducted box. Use test results obtained by the method specified in this standard can not be used to infer directly the life of the material.

3 Terms and Definitions

The following terms and definitions apply to this document. 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 artificialweathering 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 test device

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.
