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 non­governmental, 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.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www .iso .org/ patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and
expressions related to conformity assessment, as well as information about ISO’s adherence to
the World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT) see

4 Principles
4.1 This document defines the corrosion control activities conducted throughout the entire
engineering life cycle, and identifies all related elements including the objectives, corrosion sources,
materials, technology, design, research and development, manufacturing, construction, storage and
transportation, installation and commissioning, acceptance, operation, maintenance, repair, scrap
and disposal, documents and records, resource management, comprehensive assessments, etc. The
requirements of those elements are specified in accordance with holistic, systematic, coordinated and
optimized principles. The purpose of the requirements is to achieve the objectives (see 5.1) under
the premise of ensuring human health, the safety of people’s lives and property, national security and
ecological environment safety (hereinafter referred to as “safety”).
4.2 This document does not specify established procedures, professional management standards,
specifications and test methods which are in relation to the links, nodes and elements.
4.3 All elements during the corrosion control process shall be identified and have established
procedures.
5 Objectives
5.1 Corrosion control engineering efforts shall aim at improving the integration, systematization,
mutual coordination and optimization of the main life cycle, so that corrosion can be effectively controlled,
and achieving the optimum benefits of safety, cost-effectiveness, long-term operation and environmental
protection.
5.2 The objectives (see 5.1) of corrosion control engineering shall be broken down into all elements of
the life cycle. These objectives shall be communicated, implemented, maintained, regularly reviewed and
continuously improved to ensure that the whole life cycle of corrosion control engineering is compatible
with that of the protected main programme.
6 Corrosion sources
6.1 Corrosion sources shall include the following:
a) internal corrosion sources, e.g. corrosion by an internal media;
b) external corrosion sources, e.g. corrosion by the external environment.
6.2 All corrosion sources shall be identified systematically, comprehensively and accurately in
accordance with the life cycle requirements of the main programme, including new corrosion sources
unexpectedly developed during the construction processes.
6.3 Identifying corrosion sources should take into consideration the working conditions of the main
programme and the corrosion control engineering effort.
6.4 Identified corrosion sources shall be subject to the acceptance of the established procedures to
prevent any omission or wrong judgement.
7 Materials
7.1 The corrosion­resistant materials shall be selected to achieve the optimum performance of
the equipment life cycle requirements regarding safety, cost-effectiveness, long-term operation and
environmental protection.

NOTE For atmospheric corrosion, refer to ISO 11303.
7.2 The selected materials shall have the corresponding test method standards as the basis to support
their selection, acceptance and use.
NOTE For corrosion of metals and alloys, refer to ISO 6509-1.
7.3 The selected materials shall have corresponding specific performance and supporting
implementation cases as references to ensure that they can be adapted to other elements, links and
nodes and meet the requirements of the main programme.
7.4 The selected materials shall be optimized in coordination with other elements in the programme.
7.5 The selected materials shall be subject to the acceptance of the established procedures. They shall
be documented and archived.
8 Technology
8.1 The appropriate technique or multiple techniques including, but not limited to, electrochemical
protection or corrosion inhibitor shall be implemented for the corrosion control in accordance with the
different corrosion prevention goals of the main programme.
NOTE For cathodic protection, refer to ISO 12696.
8.2 The process of choosing the technologies shall consider the influence of other elements. They shall
be optimized in coordination with other elements, and achieve the optimum benefits of safety, cost-
effectiveness, long­term operation and environmental protection.
8.3 There shall be corresponding technical or test methods standards for the selected technologies for
adapted technology.
8.4 The selected corrosion control technologies shall have corresponding successful performance
and supporting implementation cases under the condition of meeting the requirements of the main

8.5 The selected technologies shall be subject to the acceptance of the established procedures and
meet the requirements of the main programme. They shall be documented and archived.
9 Design
9.1 All elements, links and nodes in the entire life cycle of corrosion control engineering shall be
systematically designed to address the corresponding corrosion risks.
9.2 Relevant design in corrosion control engineering shall be considered in a holistic, systematic,
coordinated and optimized way to ensure that all elements, links and nodes are harmonized and mutually
supported.
9.3 Green plans shall be part of the design and shall be implemented.
9.4 The applicability of the design system shall be evaluated in accordance with the objectives of
safety, cost-effectiveness, long-term operation and environmental protection. The design system shall be
