Corrosion Testing Standards

The test standard summaries are for general guidance only. Though believed to be accurate at the time of writing, this may change over time. So this information should not be used as a substitute for referring to a complete test standard, at an appropriate revision level.

Note: the terms salt spray, salt mist and salt fog are all in wide spread use within corrosion test standards. In this context they can be considered to be equivalent and interchangeable terms.

Nissan MES-M0007 Method B

Nissan Engineering Standard – Composite Corrosion Test

NES M-0007 is used to measure the degree of rusting, blistering and adhesion when the specimen is exposed to corrosive conditions such as salt spray, drying and wetting (condensate humidity)

Method B of the standard requires a Cyclic corrosion chamber which can automatically cycle between periods of salt spray, drying and wetting.

Any one of the following cycles below can be chosen to run this test in agreement with the parties concerned

  • CCT-1 -Salt Spray (35°C, 4h) → drying (60°C, 2h)→ wetting (50°C, 95% RH, 2h)
  • CCT-2- Salt Spray (35°C, 2h) → drying (60°C, 2h)→ wetting (50°C, 95% RH, 4h)
  • CCT-4 -Salt Spray (35°C, 10min) → drying (60°C, 155min)→ wetting (60°C, 95% RH, 75min), with a sub-programme of drying (60°C, 160min)→wetting (60°C, 95%RH, 80min) repeated 5 times
