ISO 11130:2017 specifies a method for assessing the corrosion resistance of metals by an alternate immersion test in salt solution, with or without applied stress. The test is particularly suitable for quality control during the manufacture of metals including aluminium alloys and ferrous materials, and also for assessment purposes during alloy development. Depending upon the chemical composition of the test solution, the test can be used to simulate the corrosive effects of marine splash zones, de-icing fluids and acid salt environments. The term "metal" as used in this document includes metallic materials with or without corrosion protection. ISO 11130:2017 is applicable to - metals and their alloys, - certain metallic coatings (anodic and cathodic with respect to the substrate), - certain conversion coatings, - certain anodic oxide coating, and - organic coatings on metals.
Abstract
Overview
EN ISO 11130:2018 (ISO 11130:2017) specifies the alternate immersion test in salt solution for assessing the corrosion resistance of metals and alloys, with or without applied stress. The method uses repeated cycles of immersion in a salt solution followed by drying to simulate aggressive environments such as marine splash zones, de-icing fluids, and acid salt conditions. It is widely used for quality control, alloy development and comparative corrosion evaluation.
Key topics and technical requirements
- Test principle: cyclic immersion and drying of specimens; evaluation of extent of attack after a defined number of cycles.
- Scope: applicable to metals and alloys, certain metallic coatings (anodic/cathodic vs substrate), conversion coatings, anodic oxide coatings, and organic coatings on metals.
- Test solutions: a neutral salt solution (recommended) and additional solutions for de-icing, acid-salt and ocean-water simulations are given. The neutral solution is prepared with sodium chloride 35 g/L ±1 g/L using high-purity water.
- Salt quality: limits on impurities and heavy metals (Cu, Ni, Pb total
