Annotation of standard text ČSN EN ISO 16701 (038122):

This International Standard specifies the test method, the reagents, and the procedure to be used in an accelerated atmospheric corrosion test constituting a 6 h exposure to a slightly acidified solution of 1 % NaCl twice weekly, followed by a condition of controlled humidity cycling between 95 % RH and 50 % RH at a constant temperature of 35 °C.
This International Standard does not specify the dimensions of the tests specimens, the exposure period to be used for a particular product, or the interpretation of the results. Such details are provided in the appropriate product specifications.
The accelerated laboratory corrosion test applies to
- metals and their alloys,
- metallic coatings (anodic or cathodic),
- chemical conversion coatings, and
- organic coatings on metallic materials.
NOTE 1: If testing low-alloy stainless steels, especially austenitic grades, according to this International Standard, there is a risk of receiving exaggerated pitting, not representative for most service environments.
NOTE 2: This International Standard is not suitable for testing of wax and oil based rust protection agents, due to the constantly elevated temperature condition of the test
