AS 2331.3.1-2001 (R2017)

Specifies a method for the neutral salt spray test for the assessment of corrosion resistance of inorganic and organic coatings on metallic substrates. The conditions within the test cabinet are tightly controlled with the pH of the collected test solution being limited to 6.5 and 7.2.RECONFIRMATION NOTICETechnical Committee MT-009 has reviewed the content of this publication and in accordance with Standards Australia procedures for reconfirmation, it has been determined that the publication is still valid and does not require change.Certain documents referenced in the publication may have been amended since the original date of publication.

This Standard sets out the method for the neutral salt spray (NSS) test for the assessment of corrosion resistance of inorganic and organic coatings on metallic substrates.NOTES: 1 The method does not specify the type of test item, the exposure period or the assessment criteria. Such details are normally specified in the relevant product Standard or determined by agreement between the purchaser and the supplier.2 It is important that the results obtained from the test are not regarded as having a direct correlation with environments in which items may be exposed in service or as indicating the relative corrosion resistance of different coatings.3 The test procedures described in this Standard do not necessarily include all of the precautions required to satisfy health and safety aspects. Care should be taken to ensure that the procedures are carried out only by people who have received suitable training. Guidance in the handling and use of hazardous chemicals is given in AS/NZS 2243.1 and AS/NZS 2243.2.
