The previous versions of this document and its superseded documents are as follows. ---First released in.1994 as GB/T 14952.3-1994, incorporated into GB/T 12967 series in.2008, released as GB/T 12967.6-2008; ---This is the first revision to GB/T 12967.6.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 12967.6 "Aluminum and aluminum alloy anode Testing methods for oxide films and organic polymer films—Part 6.Color difference and appearance quality Test method for color difference and appearance quality of organic polymer films It 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 a method for evaluating the wear resistance of the anodic oxide film and the organic polymer film layer. --- Part 3.Salt spray test. The purpose is to establish a method for evaluating the salt spray resistance of the anodic oxide film and the 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.

In.1994, my country formulated GB/T 14952.3-1994 "Aluminum and aluminum alloy anodized coloring anodized film color difference and external appearance for the first time. Visual Quality Inspection Method Visual Observation Method. In.2008, my country revised and adopted ISO /T R8125.1984 "Aluminum and Aluminum Alloy Anodizing" Determination of Color and Color Difference of Colored Anodized Films-Visual Observation Method, published GB/T 12967.6-2008 Film inspection methods - Part 6.Visual inspection for color difference and appearance quality of pigmented anodic oxide films. GB/T 12967.6-2008 and The content of GB/T 14952.3-1994 was added, and the requirements for the visual method of the colorimetric box and the test report were added. In recent years, with various surface films The anodic oxide film or organic polymer texture film made of layer preparation technology and texture processing method is more and more widely used in aluminum alloy products. And the development prospect is broad, the existing standards cannot meet the evaluation of color difference and appearance quality of different types of films, so it is necessary to use GB/T 12967.6 The evaluation methods for the color difference and appearance quality of different types of film layers are specified in this document to meet the performance testing and evaluation needs of different film layers. This document focuses on supplementing the evaluation methods for color difference and appearance quality of anodized composite films and organic polymer films.
