panimula
ISO (International Organization para sa Standardisasyon) ay isang pandaigdigang alyansa ng mga pambansang pamantayan katawan (Mga katawan ng miyembro ng ISO). Ang pag unlad ng mga internasyonal na pamantayan ay karaniwang isinasagawa sa pamamagitan ng ISO teknikal na komite. Ang bawat institusyon ng miyembro na interesado sa isang paksa kung saan itinatag ang isang teknikal na komite ay may karapatang kumatawan sa komiteng iyon. Ang mga internasyonal na organisasyon ng pamahalaan at di pamahalaan na nakikipag ugnayan sa ISO ay kasangkot din sa gawaing ito. ISO ay gumagana nang malapit sa International Electrotechnical Commission (IEC) sa lahat ng bagay ng electrical standardization.
Ang mga pamamaraan na ginamit upang bumuo ng dokumentong ito at ang mga ginagamit para sa karagdagang pagpapanatili ay inilarawan sa Bahagi 1 ng Direktiba ng ISO / IEC. Sa partikular na, pansin ay dapat bayaran sa iba't ibang mga pamantayan sa pag apruba na kinakailangan para sa iba't ibang uri ng mga dokumento ng ISO. This document has been drafted in accordance with the editing rules of ISO/IEC Directive Part 2 (tingnan iso.org/directives).

ipakilala ang
There are three main surface treatments for aluminum and its alloys:
a) anodized coating;
b) Organic coatings;
ISO 18768-1-2022 – Organic Coatings on aluminium and its alloys – Specification of methods for decorative and protective organic coatings on aluminium – Bahagi 1: Mga coating ng pulbos
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.
a) 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 Saklaw
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.
