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.
ASTM D1748
Test Method for Rust Protection by Metal Preservatives in a Humidity Cabinet
This standard specifies a test method for evaluating the rust preventative properties of metal preservatives under conditions of high humidity. Steel panels are prepared to a prescribed surface finish, dipped in the test oil, allowed to drain. They are then suspended in a special design of humidity chamber (which must meet the requirements of Military Specification JAN-H-792) where they are exposed to a temperature of 48.9C (120F) and a high (unspecified) relative humidity. This climate is maintained under constant steady state conditions. The test duration is variable.
Ascott do not currently manufacture a corrosion test chamber for compliance with this test method.
