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 & 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.

P-VW 1209

Climate Corrosion Test Cycle (VW/Audi)

This standard specifies a test method to determine the corrosion resistance of automotive condensers, water radiators and inter-coolers made of aluminium alloys. It is cyclic in nature, i.e.; test specimens are exposed to changing climates over time.

Test specimens are placed in an enclosed chamber (a separate salt mist chamber and controlled temperature/humidity chamber are generally used), and exposed to a changing climate that comprises of the following 2 cycles. 5 days exposure to the corrosion test cycle specified in P-VW 1210. This is followed by 2 days exposure to the alternating climate cycle specified in P-VW 1200. The number of cycle repeats and therefore the test duration is variable.

Please see elsewhere in this document for details of P-VW 1210 & P-VW 1200.

This is a VW/Audi test standard.
