介绍
ISO标准 (国际标准化组织) 是国家标准机构的全球联盟 (ISO 成员机构). 国际标准的制定通常通过ISO技术委员会进行. 每个对已设立技术委员会的主题感兴趣的成员机构都有权派代表参加该委员会. 与 ISO 联络的国际政府和非政府组织也参与了这项工作. ISO 与国际电工委员会密切合作 (恒温恒湿试验箱) 关于电气标准化的所有问题.

介绍
There are three main surface treatments for aluminum and its alloys:
一个) anodized coating;
b) Organic coatings;
ISO标准 18768-1-2022 – Organic Coatings on aluminium and its alloys – Specification of methods for decorative and protective organic coatings on aluminium – 部分 1: Powder coatings
C) A combination of anodized coating and organic coating.
This document and ISO 18768-2 provide performance requirements and test methods for b) organic coatings.
一个) Performance requirements and test methods for anodized coatings are given in ISO 7599, and c) combined anodized coatings and organic coatings are given in ISO 28340.
It is assumed that users are familiar with other relevant international and regional standards. These standards should be respected, and this document uses an optional system in this context.
1 范围
This document specifies methods for specifying decorative and protective powder coatings on aluminum and its alloys. It defines the characteristic properties of powder coatings and provides a test method with minimum performance requirements, taking into account the application and erodibility of the environment in which the coated aluminum is located.
This document does not apply to aluminum coil coatings.
