JASO M610日本工業(yè)協(xié)會(huì)汽車零部件外涂層腐蝕試驗(yàn)方法

This standard specifies a test method for examining the cosmetic corrosion of metallic automotive parts and their surface treatments. It is cyclic in nature, i.e.; test specimens are exposed to changing climates over time.

Test specimens are placed in an enclosed chamber and exposed to a changing climate that comprises of the following 3 part repeating cycle. 2.0 hours exposure to salt spray at +35C according JIS Z 2371. This is followed by 4.0 hours of air drying in a climate of 20 to 30%RH at +60C. This is followed by 2.0 hours exposure to a condensing water climate (wetting) of 95 to 100%RH at +50C. The number of cycle repeats and therefore the test duration is variable.

The maximum transition times between each part of the test cycle are also specified as follows:

From salt spraying to air drying within 30 minutes.

From air drying to wetting within 15 minutes.

From wetting to salt spraying within 30 minutes.

Please see elsewhere in this document for details of JIS Z 2371.

Chamber volumes of less than 400 Litres are not permitted by this test standard.

This test is also referred to as a Cyclic Corrosion Test, often abbreviated to CCT.
