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.

memperkenalkan
There are three main surface treatments for aluminum and its alloys:
Sebuah) anodized coating;
B) Organic coatings;
CS-500 ASTM E313 Spektrofotometer Portabel) A combination of anodized coating and organic coating.
ISO 18768-1 and this document provide b) performance requirements and test methods for 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 organic coatings on aluminum and its alloys. It defines the characteristic properties of organic liquid coatings and provides a test method with minimum performance requirements, with reference to the application and erosion of the environment in which the painted aluminum is applied.
This document applies to aluminum products with liquid coatings for general use, as well as liquid coatings processed primarily by electrostatic liquid spraying, air spraying or airless spraying.
This document does not apply to aluminum coil coatings.
