perkenalan
ISO (Organisasi Internasional untuk Standardisasi) adalah aliansi global badan standar nasional (badan anggota ISO). Pengembangan standar internasional biasanya dilakukan melalui komite teknis ISO. Setiap lembaga anggota yang tertarik pada subjek di mana komite teknis telah dibentuk memiliki hak untuk diwakili dalam komite tersebut. Organisasi pemerintah dan non-pemerintah internasional yang berhubungan dengan ISO juga terlibat dalam pekerjaan ini. ISO bekerja sama dengan Komisi Elektroteknik Internasional (IEC) tentang segala hal standardisasi kelistrikan.
Prosedur yang digunakan untuk mengembangkan dokumen ini dan yang digunakan untuk pemeliharaan lebih lanjut dijelaskan di Bagian 1 dari ISO/IEC Directive. Secara khusus, perhatian harus diberikan pada kriteria persetujuan berbeda yang diperlukan untuk berbagai jenis dokumen ISO. This document has been drafted in accordance with the editing rules of ISO/IEC Directive Part 2 (lihat iso.org/directives).
Harap dicatat bahwa elemen tertentu dari dokumen ini mungkin tunduk pada hak paten. ISO tidak bertanggung jawab untuk mengidentifikasi salah satu atau semua paten tersebut. Details of any patent rights identified during the preparation of the document will be found in the introduction and/or in the list of patent claims received by ISO (lihat iso.org/patents).

memperkenalkan
There are three main surface treatments for aluminum and its alloys:
Sebuah) 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 – Bagian 1: Lapisan bubuk
CS-500 ASTM E313 Spektrofotometer Portabel) A combination of anodized coating and organic coating.
This document and ISO 18768-2 provide performance requirements and test methods for b) organic coatings.
Sebuah) 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 Jangkauan
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.
