0.2 The relevance to other relevant Standardization Committee

Adopt corresponding existing technologies, professional management standards to achieve the

systemic life cycle via optimizing each other in coordination. If there is a professional technical or

professional management standard that needs to be further developed, it will be recommended to

the corresponding standardization committee to develop, select, adopt and implement. Meanwhile, it

should identify procedurally all elements in the implementation and submit traceable and supportive

documentation and records to demonstrate that the requirements of this standard have been carried

out for all elements.
0.3 Standard development guiding ideology

The completeness and verifiability of the program is emphasized. The lack of holistic, systematic, and

comprehensive control in the entire corrosion control life cycle is precisely the shortcoming that is the

important reason for the major insecurity that continue to be caused by corrosion and urgent need to

solve. This document is to propose the control requirements for the entire process and all elements

from system engineering and the whole life cycle perspective to achieve the optimal benefits of safety,

economy, long-term operation and environmental protection.
0.4 System planning

Corrosion Control Engineering Life Cycle standard system planning is divided into three levels (see

Figure 1), as follows
a) First level standards
1) Main standard: Corrosion control engineering life cycle-General requirements.

2) Supplement standards: basic terms, standard system guide, risk assessment, economy

assessment, intelligent technical specification, general requirements of corrosion control

electrochemical protection engineering life cycle.
b) Second level standards

Develop the standards for the typical corrosion control engineering areas which have serious corrosion,

safety related problems and involve a wide range, such as power plants (nuclear power, thermal power,

hydropower, wind, photovoltaic), chemical plants, reinforced concrete, pipelines, etc. According to the

model of main standards’ development, develop the corresponding specific standards for the life cycle

of professional corrosion control engineering in the corresponding industries.
c) Third level standards

According to the first level standards or second level standards, develop corresponding third level

standards that can be implemented specifically for the corrosion control to a specific project, program

or even a certain point in the main program.

0.5 The positioning of this document

This standard is the first-level standard of the whole “Corrosion control engineering life cycle” standard

series. As the basic standard of whole corrosion standards, the positioning of this document should be

most general. This is because, the corrosion exists every industry and the subjects to be protected have

different corrosion environment, condition and different corrosion control requirements. It should not

position to specific corrosion environment and condition to make corrosion technical requirement

(these standards have been under development by related standard committees). Above has been

stressed again in the committee proposal reason and working scope, and it is also the difference

between other corrosion related corrosion committee. The key is still the elements in corrosion life

cycle (these elements must be considered in whole corrosion control engineering life cycle, any lack,

loss or inappropriate controlled element may cause failure of corrosion control, even lead to disaster).

This document is for all the corrosion control engineering life cycle to all the industry, so it should be

general.

1 Scope

This document specifies the general requirements for control elements in the life cycle of corrosion

control engineering. It aims to address the current industry-wide existing issues of “only focusing on

single, isolated corrosion stage approach”, and gives a systematic approach to solve existing corrosion

problems. It aims to link the gaps between different stages of the corrosion control.

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

as well as regulates all the elements like the objectives, 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. This document is specified to meet

overall, systematic, coordinated, and optimized principles, and to achieve the optimum benefits of
