ISO 1461-2022 “Warm gegalvaniseerde bedekkings op staalprodukte – Spesifikasies en toetsmetodes”
Inleiding
ISO (Internasionale Organisasie vir Standardisasie) is 'n wêreldwye federasie van nasionale standaarde-liggame (ISO-lidliggame). Die ontwikkeling van internasionale standaarde word gewoonlik deur ISO tegniese komitees uitgevoer. Each member group interested in a subject on which a technical committee has been established has the right to be represented on the committee. Internasionale organisasies, governments and non-governmental organizations that liaise with ISO are also involved in this work. ISO werk nou saam met die Internasionale Elektrotegniese Kommissie (OVK) oor alle sake van elektriese standaardisering.
ISO/IEC Directive Part 1 describes the procedures used to develop this document as well as those used for further maintenance. In die besonder, attention should be paid to the different approval criteria required for different types of ISO files. This document has been drafted in accordance with the editorial rules of ISO/IEC Directive Part 2 (sien iso.org/directives).
Please note that some elements of this document may be the subject of patent rights. ISO is nie verantwoordelik vir die identifisering van enige of al sulke patentregte nie. Details of any patent rights identified during the development of the document will be in the profile and/or in the list of ISO patent declarations received (sien iso.org/patents).
Any trade names used in this document are provided as information for the convenience of the user and do not constitute an endorsement thereof.

Verduidelikings van die relevante standaarde van vrywillig, ISO specific terms related to conformity assessment and the expression of meaning, and the ISO in the technical barriers to trade (TBT) voldoen aan die beginsel van die wêreldhandelsorganisasie (WTO) inligting, please refer to the iso.org/iso/foreword.html.
This document has been prepared by Technical Committee ISO/TC 107, Metallic and other inorganic Coatings, Sub-Committee SC 4, Hot Dip Coatings (galvanization, ens.) in cooperation with Technical Committee CEN/TC 262 of the European Committee for Standardization (CEN) on metallic and other inorganic Coatings, According to the technical cooperation agreement between ISO and CEN (Vienna Agreement).
The fourth edition cancelates and replaces the third edition (ISO 1461:2009), wat tegnies hersien is.
ISO 1461-2022 “Warm gegalvaniseerde bedekkings op staalprodukte – Spesifikasies en toetsmetodes”
The main changes are as follows:
— Added definitions of “galvanizing”, “post-treatment”, “additional coating”, “wet storage stain” en “dubbelfase stelsel” in Hoofstuk 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 om die gebruik van verwysingsareas op sekere klein hulpkomponente op groter items te vermy;
— 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;
— Alle vereistes wat verband hou met laagdikte, insluitend Tabelle 3 en 4, in geplaas is 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 Omvang van toepassing
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, draad en gevlegte of gelaste gaasprodukte;
b) hot-dip galvanized pipes in automation equipment;
c) hot dip galvanized products (soos hegstukke) for which specific standards exist and may include additional requirements or requirements different from those in this document.
Let wel: Individual product standards can be incorporated into this document by referring to the number of galvanized coatings, of hulle kan gekombineer word met produkspesifieke wysigings. Different requirements can also be made for galvanized coatings on products designed to meet specific regulatory requirements.
