А Префаце
ИСО (Међународна организација за стандардизацију) је глобални савез националних тела за стандардизацију (Тела чланица ИСО). Развој међународних стандарда се обично спроводи преко ИСО техничких комитета. Свака институција чланица заинтересована за предмет за који је основан технички комитет има право да буде заступљена у комитету. У овај посао су укључене и владине и невладине међународне организације које су у вези са организацијама за стандардизацију. ИСО блиско сарађује са Међународном електротехничком комисијом (ИЕЦ) о свим питањима електричне стандардизације.

The procedures used to develop this document as well as those used for further maintenance are described in Part 1 ИСО/ИЕЦ директиве. Нарочито, треба обратити пажњу на различите критеријуме одобрења који су потребни за различите типове ИСО докумената. Овај документ је састављен у складу са уређивачким правилима Дел 2 ИСО/ИЕЦ директиве (види исо.орг/дирецтивес).

Увод
Unprotected steel in the atmosphere, вода, and soil is subject to corrosion, which leads to damage. Стога, to avoid corrosion damage, steel structures are usually protected to withstand the corrosion stresses that will be borne during the required service life of the structure.

There are different ways to protect steel structures from corrosion. ИСО 12944 (all parts) addresses the protection of coating systems and covers, and in the individual parts, all functions are important to achieve adequate corrosion protection. Other measures or other measures may be taken, but special agreements between the parties concerned are required.

ИСО 12944.3-2017 “Paint and varnish protection paint systems for corrosion protection of steel structures – Парт 3: Design content”

To ensure effective corrosion protection of steel structures, owners of such structures, planners, consultants, companies carrying out corrosion protection work, protective coating inspectors and manufacturers of coating materials need to have new information about corrosion protection of coating systems. It goes without saying that such information should be as complete, clear and easy to understand as possible to avoid difficulties and misunderstandings by the parties involved in the actual implementation of conservation work.

ИСО 12944 (all parts) is intended to provide this information in the form of a series of instructions. It is written for those with some technical knowledge. It is also assumed that users of ISO 12944 (all parts) are familiar with other relevant international standards, especially those dealing with surface treatment.

Although ISO 12944 (all parts) does not address financial and contractual issues, please note the fact that non-compliance with the requirements and recommendations given in ISO 12944 (all parts) can lead to serious financial consequences due to the huge impact of inadequate corrosion protection.

ИСО 12944-1 defines the overall scope of ISO 12944. It provides some basic terms and definitions and Outlines other parts of ISO 12944. Додатно, it includes general statements on health, safety and environmental protection, as well as guidelines for the use of ISO 12944 (all parts) in specific projects.

This document provides guidance on how to minimize the risk of corrosion with appropriate design measures to apply protective coating systems.

1 Обим
This document deals with basic standards for the design of steel structures coated by protective coating systems to avoid premature corrosion and degradation of the coating or structure. It gives examples of appropriate and inappropriate design, pointing out how to avoid problems with application, inspection and maintenance of paint systems. Design measures to facilitate the handling and transportation of steel structures are also considered.
