This document provides guidelines and requirements for the corrosion testing of metals and alloys in the simulated environment of deep-sea water, including principle, testing equipment, specimen preparation, testing procedure and evaluation after test. This document applies to the immersion testing, corrosion testing under stress condition and electrochemical testing in the simulated environment of deep-sea water in the laboratory. Testing of other materials such as composites and elastomers can also be carried out in the simulated environment of deep-sea water with reference to this document, but the evaluation of these materials after the testing is different from that of metals and alloys.

ISO 21207:2015 defines two accelerated corrosion test methods to be used in assessing the corrosion resistance of products with metals in environments where there is a significant influence of chloride ions, mainly as sodium chloride from a marine source or by winter road de-icing salt, and of corrosion-promoting gases from industrial or traffic air pollution.
ISO 21207:2015 specifies both the test apparatus and test procedures to be used in executing the accelerated corrosion tests.
The methods are especially suitable for assessing the corrosion resistance of sensitive products with metals, e.g. electronic components, used in traffic and industrial environments.

The document specifies a method for undertaking uniaxial constant load testing of the susceptibility of a metal, or an alloy, to stress corrosion cracking (SCC) in high-purity water environments at high temperature (above the boiling point of water at normal pressures) and pressure. The test method is particularly applicable to simulated primary water environments of light water reactors (LWRs). The test method enables assessment of the relative resistance to SCC of a material in different environments and the comparative resistance of different materials (using the same environment, specimen dimensions and loading). The terms “metal” and “alloy”, as used in the document, include weld metals and weld heat affected zones.

This document specifies the apparatus, the reagents and the procedure to be used in conducting the
neutral salt spray (NSS), acetic acid salt spray (AASS) and copper-accelerated acetic acid salt spray
(CASS) tests for assessment of the corrosion resistance of metallic materials, with or without permanent
or temporary corrosion protection.
It also describes the method employed to evaluate the corrosivity of the test cabinet environment.
It does not specify the dimensions or types of test specimens, the exposure period to be used for a
particular product, or the interpretation of results. Such details are provided in the appropriate product
specifications.
The salt spray tests are particularly useful for detecting discontinuities, such as pores and other defects,
in certain metallic, organic, anodic oxide and conversion coatings.
The NSS test is particularly applicable to:
— metals and their alloys;
— metallic coatings (anodic and cathodic);
— conversion coatings;
— anodic oxide coatings;
— organic coatings on metallic materials.
The AASS test is especially useful for testing decorative coatings of copper + nickel + chromium, or
nickel + chromium. It has also been found suitable for testing anodic and organic coatings on aluminium.
The CASS test is useful for testing decorative coatings of copper + nickel + chromium, or nickel +
chromium. It has also been found suitable for testing anodic and organic coatings on aluminium.
The salt spray methods are all suitable for checking that the quality of a metallic material, with or
without corrosion protection, is maintained. They are not intended to be used for comparative testing
as a means of ranking different materials relative to each other with respect to corrosion resistance or
as means of predicting long-term corrosion resistance of the tested material.

This document specifies performance requirements for cathodic protection of steel in cement-based concrete, in both new and existing structures. It covers building and civil engineering structures, including carbon steel reinforcement and prestressed reinforcement embedded in the concrete. It is applicable to uncoated steel reinforcement and to organic-coated steel reinforcement. It is not applicable to reinforced concrete containing electrically conductive fibres (e.g. carbon or steel).
This document applies to steel embedded in atmospherically exposed, buried, immersed and tidal elements of buildings or structures.
This document is only applicable to the applications of cathodic protection to steel in concrete which are designed with the intention to, and can be demonstrated to, meet the criteria of protection specified in 8.6. This requires the provision of sufficient performance monitoring systems as specified in 6.3 to all parts of the structure intended to be protected, in order to assess the extent to which the criteria in 8.6 are met.
This document does not apply to galvanic anodes or systems applied into patch repairs to reduce the effects of ‘incipient anodes’. This document does also not apply to any form of cathodic protection systems or other electrochemical treatments that either cannot meet the requirements of 8.6 or are not provided with the performance monitoring systems (see 6.3) that are necessary to assess whether the criteria of protection specified in 8.6 are met.
NOTE 1 Annex A gives guidance on the principles of cathodic protection and its application to steel in concrete.
NOTE 2 This document, while not specifically intended to address cathodic protection of steel in any electrolyte except concrete, can be applied to cathodic protection of steel in other cementitious materials such as are found, for example, in early 20th century steel-framed masonry, brick and terracotta clad buildings. In such applications, additional considerations specific to these structures are required in respect of design, materials and installation of cathodic protection; however, the requirements of this document can be applied to these systems.

This document provides information on methods suitable for assessing the likelihood of leakage due to external corrosion of well casings and to evaluate the need for cathodic protection, as well as methods of providing cathodic protection to the external part of these wells in contact with the soil. It also defines requirements for monitoring of performance of CP systems.
Onshore and offshore wells are included in the scope. However, for offshore wells where protection is provided by anodes on the wellhead structure, it is recognized that it might not be practical to achieve full protection of well casings.
This document applies to any gas, oil or water well with metallic casing, whether cemented or not.
However, in special conditions (shallow casings: e.g. 50 m, and homogeneous soil), EN 12954 can be used to achieve the cathodic protection and assess its efficiency.
The general requirements of EN 12954 apply; this document details additional, specific, requirements for CP of well casings.
This document applies to production and injection wells. References later in this document to production also apply to injection.

1.1 This document specifies procedures for designing, preparing and using pre-cracked specimens for investigating the susceptibility of metal to stress corrosion cracking (SCC) by means of tests conducted under rising load or rising displacement. Tests conducted under constant load or constant displacement are dealt with in ISO 7539-6.
The term “metal” as used in this document includes alloys.
1.2 Because of the need to confine plasticity at the crack tip, pre-cracked specimens are not suitable for the evaluation of thin products such as sheet or wire and are generally used for thicker products including plate, bar, and forgings. They can also be used for parts joined by welding.
1.3 Pre-cracked specimens can be stressed quantitatively with equipment for application of a monotonically increasing load or displacement at the loading points.
1.4 A particular advantage of pre-cracked specimens is that they allow data to be acquired from which critical defect sizes, above which stress corrosion cracking can occur, can be estimated for components of known geometry subjected to known stresses. They also enable rates of stress corrosion crack propagation to be determined.
1.5 A principal advantage of the test is that it takes account of the potential impact of dynamic straining on the threshold for stress corrosion cracking.
1.6 At sufficiently low loading rates, the threshold stress intensity factor for susceptibility to stress corrosion cracking, KISCC, determined by this method can be less than or equal to that obtained by constant load or displacement methods and can be determined more rapidly.

This document establishes the general principles to be adopted to minimize the effects of stray current
corrosion caused by direct-current (d.c.) on buried or immersed pipeline systems. A brief description of
alternating current (a.c.) effects is provided.
The document is intended to offer guidance for:
— the design of cathodic protection systems which may produce stray currents;
— the design of pipeline systems, or elements of pipeline systems, which are to be buried or immersed and which may be subject to stray current corrosion;
— the selection of appropriate protection or mitigation measures.
The effects of a.c. induced voltages are not dealt with in detail in this document because they are
covered in ISO 18086. General principles and guidelines are, however, provided.
Stray current corrosion can also occur internally in systems containing a conducting electrolyte e.g.
near insulating joints or high resistance pipe joints in pipelines transporting conductive fluids.
Internal corrosion risks from stray currents are not dealt with in detail in this document but principles
and measures described here can be applicable for minimizing the interference effects.
Stray currents can also cause other effects such as overheating. These other effects are not covered in
this document.
A.C. currents can induce unacceptable touch voltages on above-ground appurtenances of pipeline
systems. These are not covered in detail in this document. They are covered in EN 50443, EN 61140,
IEC 60364-4-41, IEC TS 60479-1, IEC 60364-5-52, IEC /TS 61201, and IEC TR 60479-5.
Systems which may be affected by stray currents include buried or immersed metal structures such as:
a) pipeline systems;
b) metal sheathed cables;
c) tanks and vessels;
d) earthing systems;
e) steel reinforcement in concrete;
f) sheet steel piling.
This document provides details only for pipeline systems although the principles can be applied to
other buried structures. The EN 50162 series of standards also provide guidance for railway related
structures.

on the threshold for stress corrosion cracking.
1.6 At sufficiently low loading rates, the threshold stress intensity factor for susceptibility to stress
corrosion cracking, KISCC, determined by this method can be less than or equal to that obtained by
constant load or displacement methods and can be determined more rapidly.

This document specifies procedures for the removal of corrosion products formed on metal and alloy corrosion test specimens during their exposure in corrosive environments. For the purpose of this document, the term "metals" refers to pure metals and alloys.
The specified procedures are designed to remove all corrosion products without significant removal of base metal. This allows an accurate determination of the mass loss of the metal, which occurred during exposure to the corrosive environment.
In some cases, these procedures are also applicable to metal coatings, providing the possible effects from the substrate are considered.

1.1 This document specifies procedures for designing, preparing and using pre-cracked specimens for investigating the susceptibility of metal to stress corrosion cracking (SCC) by means of tests conducted under rising load or rising displacement. Tests conducted under constant load or constant displacement are dealt with in ISO 7539-6. The term “metal” as used in this document includes alloys. 1.2 Because of the need to confine plasticity at the crack tip, pre-cracked specimens are not suitable for the evaluation of thin products such as sheet or wire and are generally used for thicker products including plate, bar, and forgings. They can also be used for parts joined by welding. 1.3 Pre-cracked specimens can be stressed quantitatively with equipment for application of a monotonically increasing load or displacement at the loading points. 1.4 A particular advantage of pre-cracked specimens is that they allow data to be acquired from which critical defect sizes, above which stress corrosion cracking can occur, can be estimated for components of known geometry subjected to known stresses. They also enable rates of stress corrosion crack propagation to be determined. 1.5 A principal advantage of the test is that it takes account of the potential impact of dynamic straining on the threshold for stress corrosion cracking. 1.6 At sufficiently low loading rates, the threshold stress intensity factor for susceptibility to stress corrosion cracking, KISCC, determined by this method can be less than or equal to that obtained by constant load or displacement methods and can be determined more rapidly.

This document specifies protection criteria for determining the AC corrosion risk of cathodically protected pipelines.
It is applicable to buried cathodically protected pipelines that are influenced by AC traction systems and/or AC power lines.
In the presence of AC interference, the protection criteria given in ISO 15589-1 are not sufficient to demonstrate that the steel is being protected against corrosion.
This document provides limits, measurement procedures, mitigation measures, and information to deal with long-term AC interference for AC voltages at frequencies between 16,7 Hz and 60 Hz and the evaluation of AC corrosion likelihood.
This document deals with the possibility of AC corrosion of metallic pipelines due to AC interferences caused by conductive, inductive or capacitive coupling with AC power systems and the maximum tolerable limits of these interference effects. It takes into account the fact that this is a long-term effect, which occurs during normal operating conditions of the AC power system.
This document does not cover the safety issues associated with AC voltages on pipelines. These are covered in national standards and regulations (see, e.g., EN 50443).

This document specifies a test method for determining the stress corrosion crack (SCC) growth rate of steels and alloys under static-load conditions in high-temperature water, such as the simulated water environment of light water reactors. The crack length of the specimen is monitored by a potential drop method (PDM) during the test in an autoclave. The test method is applicable to stainless steels, nickel base alloys, low alloy steels, carbon steels and other alloys.
