Foreword
ISO (the International Organization for Standardization) is a worldwide
federation of national standards bodies (ISO member bodies). The work of
preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which
a technical committee has been established has the right to be represented
on that committee. International organizations, governmental and non-
governmental, in liaison with ISO, also take part in the work. ISO
collaborates closely with the International Electrotechnical Commission
(IEC) on all matters of electrotechnical standardization.
Draft International Standards adopted by the technical committees are
circulated to the member bodies for voting. Publication as an International
Standard requires approval by at least 75 % of the member bodies casting
a vote.
International Standard ISO 12944-6 was prepared by Technical Committee
ISO/TC 35, Paints and varnishes, Subcommittee SC 14, Protective paint
systems for steel structures.
ISO 12944 consists of the following parts, under the general title Paints
and varnishes — Protective paint systems for steel structures:
— Part 1: General introduction
— Part 2: Classification of environments
— Part 3: Design considerations
— Part 4: Types of surface and surface preparation
— Part 5: Protective paint systems
— Part 6: Laboratory performance test methods
— Part 7: Execution and supervision of paint work
— Part 8: Development of specifications for new work and maintenance

Introduction
Unprotected steel in the atmosphere, in water and in soil is subject to
corrosion that may lead to damage. Therefore, to avoid corrosion damage,
steel structures are normally protected to withstand the corrosion stresses
during the service life required of the structure.
There are different ways of protecting steel structures from corrosion.
ISO 12944 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, it is
necessary for owners of such structures, planners, consultants, companies
carrying out corrosion protection work, inspectors of protective coatings
and manufacturers of coating materials to have at their disposal state-of-
the-art information in concise form on corrosion protection by paint
systems. Such information has to be as complete as possible,
unambiguous and easily understandable to avoid difficulties and
misunderstandings between the parties concerned with the practical
implementation of protection work.
This International Standard — ISO 12944 — 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 is familiar with other relevant International Standards, in
particular those dealing with surface preparation, as well as relevant
national regulations.
Although ISO 12944 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 this standard may result in serious financial
consequences.
ISO 12944-1 defines the overall scope of all parts 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
for a given project.
ISO 12944-6 provides a way of assessing paint systems by means of
laboratory tests in order to be able to select the most suitable.

Paints and varnishes — Corrosion protection of steel structures
by protective paint systems
Part 6:
Laboratory performance test methods
1 Scope
This part of ISO 12944 specifies laboratory test methods and test conditions for the assessment of paint systems for
the corrosion protection of steel structures. The test results are to be considered as an aid in the selection of
suitable paint systems and not as exact information for determining durability.
This part of ISO 12944 covers protective paint systems designed for application to uncoated steel, hot-dip-
galvanized steel and steel surfaces with thermally sprayed zinc coatings.
This part of ISO 12944 does not apply to protective paint systems for electroplated or painted steel.
Certain tests in this part of ISO 12944 are not applicable to many water-borne paint systems (see 4.2).
Nevertheless, some water-borne paint systems are amenable to testing and evaluation using the procedures
described herein, and their results could be taken into account.
The environments defined in ISO 12944-2 are considered.

3 Definitions
For the purposes of this part of ISO 12944, the following definitions apply in addition to those given in ISO 12944-1.
3.1 artificial ageing: A procedure designed to accelerate the ageing of a paint system, i.e. to reduce the
corrosion-protective efficiency more rapidly than by natural weathering.
3.2 visual assessment method: A method for visually assessing a paint system in accordance with one of the
parts of ISO 4628.
3.3 complementary assessment method: A method used in addition to the visual assessment methods.
3.4 requirements: Test results that must be achieved for a paint system in order for the system to be considered
suitable for use in corrosion protection.
4 General
4.1 Relationship between artificial ageing and natural exposure
The selection of a paint system for a specific situation should preferably be based on experience from the use of the
system in similar cases. The reason is that the durability of a paint system depends on many external factors such
as the environment, the design of the structure, the surface preparation, and the application and d
