4 General principles
4.1 Objectives
The purpose of risk assessment is to:
a) improve the integration, systematization, mutual coordination and optimization of all elements of
the corrosion control engineering life cycle;
b) create and protect the benefits of human health and safety, cost-effectiveness, long-term operation
and environmental protection.
4.2 Principles
For risk assessment to be effective, an organization should, at all levels, conform to the following
principals:
a) risk assessment should be based on ISO 23123 or other risk criteria, and should be performed on all
elements of the corrosion control engineering life cycle;
b) risk assessment is transparent and inclusive;
c) risk assessment is dynamic, iterative and responsive to change;
d) risk assessment takes human factors into account;
e) risk assessment is systematic, structured and timely.
5 Risk assessment procedure
5.1 General
The risk assessment process of a corrosion control engineering life cycle includes the following steps.
a) Identify the corresponding actual risk of all elements in the corrosion control engineering life cycle.
b) Research and analyse whether all elements are implemented in accordance with ISO 23123.
c) Analyse the evaluation result and submit the identified assessment report.
5.2 Risk identification
The risk of all elements of the corrosion control engineering life cycle should be identified collectively and
accurately in accordance with the actual situation of the main programme.

The objectives should be analysed as follows.
a) Whether the corrosion control engineering is implemented in accordance with the principles given
in Clause 4.
b) Whether the objectives are implemented into the risk analysis of all elements of the corrosion
control engineering life cycle, and communicated, and maintained in all aspects of the life cycle.
In addition, whether the objectives adapt the corrosion control engineering life cycle and the
protected main programme life cycle. The corrosion control engineering life cycle depends on,
serves and assists the main programme. In some cases, it is also restricted to the main programme.

The corrosion sources should be analysed as follows.
a) Whether the internal and external corrosion sources are identified comprehensively and accurately.
b) Whether new corrosion sources generated in the implementation process are identified
comprehensively and accurately.
c) Whether the conditions of the main programme and the influence of the corrosion control
engineering body are taken into account.
d) Whether an established procedure has been identified.
e) How the corrosion and its sources are monitored and mitigated, which shall be analysed during the

of the corrosion control process.
b) Whether the design takes into account the integration, systematization, mutual coordination and
optimization during the entire life cycle of corrosion control engineering.
c) Whether a green plan has been made.
d) Whether the design system is constantly improved to meet the requirements of the main

e) Whether the design documents are subject to the acceptance of established procedures, and
whether they are to be documented and archived.
5.3.4 Research and development
The research and development should be analysed as follows.
