This document specifies the apparatus and test procedure to be used when conducting accelerated corrosion tests for the comparative quality evaluation of metallic materials with or without permanent corrosion protection or temporary corrosion protection in salt-contaminated outdoor environments. The test involves cyclic exposure of the specimens to neutral salt mist, “dry” and “wet” conditions. The type of test specimen and the exposure period are not specified. The particular advantages of this test over common accelerated tests such as the neutral salt spray (NSS) test lie in its ability to better reproduce the corrosion that occurs in outdoor salt-contaminated environments. This document is applicable to: metals and their alloys; metallic coatings (anodic and cathodic); conversion coatings; anodic oxide coatings; organic coatings on metallic materials. NOTE Methods of test for coatings to determine their resistance, in the presence of scribe marks through to the substrate, to various cyclic corrosion conditions which include the condensation of water on the test specimens during periods of humidity are given in ISO 11997-1.

This document specifies a method for the determination of resistance to stress corrosion cracking (SCC) of copper and copper-zinc alloys in ammonia vapour. This document covers the method of sampling, the types of specimens, the loading procedure, the type of environment and the interpretation of results. This document is aimed at determining resistance to SCC as a function of the chemical composition, the method of manufacture of copper and copper-zinc alloys. This document applies to wrought copper and copper-zinc alloys in the form of products and parts. This document can be used to rank materials performance and select candidate materials under atmospheres containing ammonia. However, the results of this test should not be considered as an absolute criterion for the quality of alloys. This document specifies a method for exposing test specimens in ammonia vapour coexisting with an aqueous ammonia solution and specifies the environmental conditions and test procedures. This document specifies two methods of loading: under constant total strain; under constant load. It does not cover slow strain rate test methods and determination of maximum admissible stress by the method of permanent deformation for copper and copper-zinc alloys, although an effort is now being made to apply such methods to these alloys (see ISO 7539-7).

This document specifies an atmospheric accelerated test procedure in two closely related variants that contain intermittent salt exposure combined with dynamic humidity patterns: variant A at constant dew point and variant B at constant temperature. These variants are used in assessing the corrosion resistance of metals in environments where there is a significant influence of chloride ions, mainly as sodium chloride from, for example, winter road de-icing salt. The results obtained do not permit far-reaching conclusions on the corrosion resistance of the tested metallic material under the whole range of environmental conditions in which it can be used. Nevertheless, the method provides information on the relative corrosion resistance of a material exposed to a salt-contaminated environment with varying humidity conditions.
The two accelerated laboratory corrosion test variants are applicable to:
— metals and their alloys (ferrous and non-ferrous);
— metallic coatings;
— chemical conversion coatings;
— organic coating on metals;
— a combination of materials and coatings that include galvanic interactions and/or crevice conditions.
NOTE 1 If testing low-alloy stainless steels according to this document, especially austenitic grades, there is a risk of exaggerated pitting, which is not representative of most service environments.
NOTE 2 This document is not suitable for testing of wax and oil-based rust protection agents, due to the constantly elevated temperature condition of the test.
This document also specifies requirements on the test equipment and contains detailed procedures for quality control, including recommended instrumentation.
This document does not specify the dimensions of the tests specimens, the exposure period to be used for a particular product, or the interpretation of the results. Such details are provided in the appropriate product specifications.

SIGNIFICANCE AND USE
4.1 Different electroplating systems can be corroded under the same conditions for the same length of time. Differences in the average values of the radius or half-width or of penetration into an underlying metal layer are significant measures of the relative corrosion resistance of the systems. Thus, if the pit radii are substantially higher on samples with a given electroplating system, when compared to other systems, a tendency for earlier failure of the former by formation of visible pits is indicated. If penetration into the semi-bright nickel layer is substantially higher, a tendency for earlier failure by corrosion of basis metal is evident.
SCOPE
1.1 This test method provides a means for measuring the average dimensions and number of corrosion sites in an electroplated decorative nickel plus chromium or copper plus nickel plus chromium coating on steel after the coating has been subjected to corrosion tests. This test method is useful for comparing the relative corrosion resistances of different electroplating systems and for comparing the relative corrosivities of different corrosive environments. The numbers and sizes of corrosion sites are related to deterioration of appearance. Penetration of the electroplated coatings leads to appearance of basis metal corrosion products.
1.2 The values stated in SI units are to be regarded as the standard.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
