Perkenalan
ISO (Organisasi Internasional untuk Standardisasi) adalah federasi global badan standar nasional (badan anggota ISO). Pengembangan standar internasional biasanya dilakukan melalui komite teknis ISO. Each member group interested in a subject on which a technical committee has been established has the right to be represented on the committee. Organisasi internasional, governments and non-governmental organizations that liaise with ISO are also involved in this work. ISO bekerja sama dengan Komisi Elektroteknik Internasional (IEC) tentang segala hal standardisasi kelistrikan.

This document has been prepared by Technical Committee ISO/TC 107, Pelapis logam dan anorganik lainnya, Sub Komite SC 4, Hot Dip Coatings (galvanization, dll.) bekerja sama dengan Komite Teknis CEN/TC 262 dari Komite Standardisasi Eropa (SEN) on metallic and other inorganic Coatings, According to the technical cooperation agreement between ISO and CEN (Perjanjian Wina).

The fourth edition cancelates and replaces the third edition (ISO 1461:2009), yang secara teknis telah direvisi.

ISO 1461-2022 “Lapisan galvanis hot dip pada produk baja – Spesifikasi dan metode pengujian”

Perubahan utamanya adalah sebagai berikut:

— Menambahkan definisi dari “menggembleng”, “pasca perawatan”, “lapisan tambahan”, “noda penyimpanan basah” Dan “sistem dua fasa” di Bab 3;

-The difficulty of removing flux residues and zinc ash when restricted access is recognized in 6.1;

– The reference area selection procedure has been clarified and additional requirements have been added in 6.2.3 untuk menghindari penggunaan area referensi pada komponen bantu kecil tertentu pada item yang lebih besar;

— Modified refurbishment requirements for uncoated areas: removed the requirement for zinc-containing paint pigments to comply with ISO 3549; Annex C has been extended to include additional information on the applicability of the different refurbishment methods given in 6.3;

— All requirements related to coating thickness, including Tables 3 Dan 4, have been placed in 6.5, including requirements related to the dimensions of items previously in the control sample in 6.2.3; The new requirements for these steels in 6.5 recognize the lower coating thickness that results in ultra-low reactivity steels;

– Updated corrosion resistance information for galvanized coatings, including long-term corrosion resistance in reference to ISO 9224 in Appendix E.

1 Lingkup aplikasi
This document specifies the general properties of hot dip galvanized coatings and test methods for hot dip galvanized coatings applied by immersing steel products (including certain castings) in a zinc melt (containing no more than 2% of other metals). This document does not apply to:

A) continuous hot dip galvanized sheet, wire and braided or welded mesh products;

B) hot-dip galvanized pipes in automation equipment;

C) hot dip galvanized products (such as fasteners) for which specific standards exist and may include additional requirements or requirements different from those in this document.

Catatan: Individual product standards can be incorporated into this document by referring to the number of galvanized coatings, or they can be combined with product-specific modifications. Different requirements can also be made for galvanized coatings on products designed to meet specific regulatory requirements.

ISO 1461-2022 “Lapisan galvanis hot dip pada produk baja – Spesifikasi dan metode pengujian”

This document does not apply to post-treatment or additional coating of hot dip galvanized products.
