本文件规定了在盐污染的室外环境中进行加速腐蚀试验的仪器和试验程序，用于比较评估金属材料是否具有永久腐蚀防护或临时腐蚀防护。试验涉及将试样循环暴露在中性盐雾、“干燥”和“潮湿”条件下。未规定试样类型和暴露时间。 与普通加速试验（如中性盐雾（NSS）试验）相比，该试验的特殊优势在于，它能够更好地重现室外盐污染环境中发生的腐蚀。 本文件适用于 -金属及其合金， -金属涂层（阳极和阴极）， -转化膜， -阳极氧化涂层，以及 -金属材料上的有机涂层。 注:ISO 11997-1中给出了涂层的试验方法，以确定涂层在有划线标记的情况下对各种循环腐蚀条件（包括潮湿期间试样上的水凝结）的耐受性。

This document specifies the apparatus and test procedure to be used in conducting accelerated corrosion tests for the comparative 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, and — 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.
