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

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

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 the following

This document was prepared by Technical Committee [or Project Committee] ISO/TC 156, [corrosion of

metals and alloys], Subcommittee SC 1, [corrosion control engineering life cycle].

This standard is a general top-level standard supporting the document of ISO/CD 23123 in the standard

system. This standard whose assessed object is the risk of Corrosion control engineering life cycle is

based on ISO/CD 23123 to ensure the optimal benefits of safety, economy, long-term operation and

environmental protection and evaluate the risk of all risk elements in the whole process of corrosion

control engineering life cycle is carried out with the procedures specified in ISO/CD 23123. It is the

basic standard for risk assessment of the whole life cycle of corrosion control engineering existing in all

walks of life, and evaluate the risk of all elements in the whole process of corrosion control engineering

life cycle is implemented in accordance with the procedures specified in ISO/CD 23123, while achieving

all elements and elements, local and entire could link up with each other, optimize with each other,

coordinate with each other and support with each other in the interwoven or not at the same time, and

form a holistic, systematic, comprehensive by third party risk assessment. Therefore, it should be as

This document specifies the general requirements for risk assessment in the life cycle of corrosion

It is applicable to risk assessment of all types of corrosion control engineering programs.

The following documents are referred to in the text in such a way that some or all of their content

constitutes requirements of this document. For dated references, only the edition cited applies. For

undated references, the latest edition of the referenced document (including any amendments) applies.

ISO and IEC maintain terminological databases for use in standardization at the following addresses:

An essential part of all kinds of corrosion control engineering including corrosion sources,

materials, technology, design, research and development, manufacturing, construction, storage and

transportation, installation and commissioning, acceptance, operation, maintenance, repair, scrapping

and disposal, documents and records, resource management, comprehensive assessments, etc.

Aiming at achieving the optimum benefits of safety, economy, long-term operation and environmental

protection, all elements in the whole process chain of corrosion control engineering are taken as objects,

and the principles and methods of evaluation are applied to identify and analyze whether all elements in

the corrosion control engineering life cycle are implemented and identified according to ISO/CD 23123.

The activities of risk assessment should predict the possibility and severity of the accident or damage to

people's life and property, and put forward control measures and draw conclusions of risk assessment.

Risk assessment includes three steps: risk identification, risk analysis and risk evaluation.

Process of finding, recognizing and describing corrosion risk of all elements in the corrosion control

Note 1 to entry: risk identification takes all elements in the corrosion control engineering life cycle as the object.

Process of comparing the results of risk analysis and summarize the traceability and supporting

documents to determine whether the corrosion risk of all elements in the corrosion control engineering

The objective should be aim at achieving the optimum benefits of economy, long-term operation and

environmental protection on the basis of the operation of economic society which should ensure

human health, people's life and property safety, national security and ecological environment safety

Corrosion control engineering life cycle is the object of this document. And risk assessment is performed

on all elements of ISO/CD 23123 that affect to achieve the optimum benefits of safety, economy, long-

term operation and environmental protection, the elements of risk assessment include corrosion

sources, materials, technology, research and development, design, manufacturing, construction,

storage and transportation, installation and commissioning, acceptance, operation, maintenance,

repair, lifetime extension, scrapping and disposal, documents and records, resource management,
