This document was first published in.1991, and was revised for the first time in.2014.This is the second revision.IntroductionAluminum and aluminum alloy anodic oxide films and organic polymer films are mainly used for the protection and decoration of aluminum and aluminum alloy surfaces. It is widely used in many fields such as furniture, home appliances, decoration, food packaging, mechanical parts and functional materials. GB/T 12967.4 "Aluminum and aluminum alloy anode Test methods for oxide films and organic polymer films - Part 4.Determination of light and heat resistance Weather resistance and heat resistance test methods for organic polymer films, which can be used to evaluate the discoloration, loss Test methods for aging damage such as light, chalking, corrosion, cracking, etc., can also be used to compare the process quality of samples with similar coatings.

GB/T 12967 consists of five parts. --- Part 1.Determination of abrasion resistance. The purpose is to establish the wear resistance evaluation method of anodic oxide film and organic polymer film layer; --- Part 3.Salt spray test. The purpose is to establish the evaluation method of salt spray resistance of anodic oxide film and organic polymer film layer; --- Part 4.Determination of light and heat resistance. The purpose is to establish the weather resistance and resistance of the anodic oxide film and the organic polymer film layer. Thermal performance evaluation method; --- Part 5.Determination of rupture resistance.

The purpose is to establish the color difference and appearance quality of the anodized film and organic polymer film layer Evaluation method. In.1991, my country identically adopted ISO 6581.1980 "Measurement of UV resistance of anodized and colored anodic oxide films of aluminum and aluminum alloys". For the first time, GB/T 12967.4-1991 "Determination of Ultraviolet Light Resistance of Anodized Colored Anodized Films of Aluminum and Aluminum Alloys" was formulated. In.2014, my country revised and adopted ISO 6581.2010 "Determination of UV resistance of anodized and colored anodic oxide films of aluminum and aluminum alloys", Published GB/T 12967.4-2014 "Testing methods for anodized films of aluminum and aluminum alloys - Part 4.Colored anodic oxide films are resistant to ultraviolet light Determination of Performance". GB/T 12967.4-2014 replaces GB/T 12967.4-1991, increasing the scope of application, control samples and tests reporting requirements. In recent years, anodized films or organic polymer texture films made of various surface film preparation techniques and texture processing methods The application of aluminum alloy products is more and more extensive, and the development prospect is broad. The existing standards cannot meet the weather resistance and heat resistance of different types of films. Therefore, it is necessary to specify in GB/T 12967.4 the light and heat resistance test and evaluation methods applicable to different types of films, so as to be suitable for It should meet the performance testing and evaluation requirements of different film layers. This document focuses on supplementing the natural exposure test of anodized composite film, organic polymer film, fluorescent UV weather resistance test, xenon lamp plus Rapid weather resistance test and heat resistance test and evaluation method of anodized films and organic polymer films.
