Overview

EN ISO 12944-7:2017 - part of the ISO 12944 series - specifies requirements for the execution and supervision of paint work on steel structures, either in the workshop or on site. It focuses on ensuring that protective paint systems for corrosion protection are applied and inspected correctly to achieve the intended service life. This part does not cover surface preparation (see ISO 12944‑4), metallic coatings, pre‑treatment methods (phosphating, chromating) or certain paint application methods (dipping, powder or coil coating).

Key Topics

The standard addresses practical and supervisory aspects of painting steel structures, including:

• Preconditions for execution
  • Qualifications of personnel and contractors
  • Condition of substrate prior to coating
  • Health, safety and environmental protection measures
• Coating materials
  • Supply chain responsibilities and storage requirements for coating materials
• Execution of paint work
  • General requirements and acceptable application conditions
  • Common application methods: brush, roller, spray, and other methods
  • Pre‑work evaluation and readiness checks
• Supervision and inspection
  • Role and duties of supervisors and inspectors
  • Use of measurement and test instruments for quality control
  • Assessment criteria for coatings during and after application
• Reference areas and specimens
  • Creation and use of Type A/Type B reference areas and reference specimens for visual and technical comparison
  • Record keeping for reference areas and assessment outcomes

Applications and Users

EN ISO 12944-7:2017 is practical for anyone involved in corrosion protection by painting of steel structures:

• Owners and asset managers specifying required supervision and acceptance criteria
• Designers and consultants writing coating specifications and inspection plans
• Contractors and applicators executing workshop or site painting works
• Coating inspectors and quality assurance personnel performing assessments and acceptance tests
• Manufacturers and suppliers ensuring materials are supplied and stored per project requirements

Typical applications include bridges, industrial plants, offshore and onshore steel structures, and heavy civil engineering assets where durable corrosion protection is required.

Related Standards

• ISO 12944‑1 (general principles)
• ISO 12944‑4 (surface preparation) - specifically referenced as outside the scope of Part 7
• ISO 12944‑5 (examples of protective paint systems)
• Other parts of the ISO 12944 series covering durability, laboratory testing and design guidance

EN ISO 12944-7:2017 helps align painting practice, supervision and inspection with internationally recognized requirements to improve coating performance and reduce lifecycle corrosion risk.

ISO 12944-7:2017(E)
Introduction
Unprotected steel in the atmosphere, in water and in soil is subjected to corrosion that can lead to
damage. Therefore, to avoid corrosion damage, steel structures are normally protected to withstand
the corrosion stresses to which they will be subjected during the service life required of the structure.
There are different ways of protecting steel structures from corrosion. ISO 12944 (all parts) deals with
protection by paint systems and covers, in the various parts, all features that are important in achieving
adequate corrosion protection. Additional or other measures are possible but require particular
agreement between the interested parties.
In order to ensure effective corrosion protection of steel structures, owners of such structures, planners,
consultants, companies carrying out corrosion protection work, inspectors of protective coatings
and manufacturers of coating materials need to have at their disposal state-of-the-art information in
concise form on corrosion protection by paint systems. It is vital that such information is as complete as
possible, unambiguous and easily understandable to avoid difficulties and misunderstandings between
the parties concerned with the practical implementation of protection work.
ISO 12944 (all parts) is intended to give this information in the form of a series of instructions. It is
written for those who have some technical knowledge. It is also assumed that the user of ISO 12944 (all
parts) is familiar with other relevant International Standards, in particular those dealing with surface
preparation.
Although ISO 12944 (all parts) does not deal with financial and contractual questions, attention is
drawn to the fact that, because of the considerable implications of inadequate corrosion protection,
non-compliance with requirements and recommendations given in ISO 12944 (all parts) can result in
serious financial consequences.
ISO 12944-1 defines the overall scope of ISO 12944. It gives some basic terms and definitions and a
general introduction to the other parts of ISO 12944. Furthermore, it includes a general statement on
health, safety and environmental protection, and guidelines for using ISO 12944 (all parts) for a given
project.
This document describes how paint work on steel structures is to be executed and supervised after
the surface has been prepared in accordance with ISO 12944-4. Examples of protective paint systems
suitable for this purpose are given in ISO 12944-5.
