Designed by Volvo, a Swedish multinational luxury vehicle manufacturer headquartered in Gothenburg, the Volvo VCS 1027, 1449 standard serves as a general purpose atmospheric corrosion test and is applied to a wide variety of materials, coatings and material interactions. This standard is primarily designed to allow assessment of the corrosion resistance of metals in environments where chloride ions such as sodium chloride from a marine source or winter road de-icing salt have adverse effects.
The test method described is cyclical in nature, meaning test samples are exposed to climates that change over time. During testing, samples are placed in a closed chamber and exposed to changing climatic conditions. The first 5 days consist of the following 3 part repeating cycles:
The last 2 days are exposed to a constant climate of 50 degrees and 70 percent relative humidity for 48 hours. This total 7-day test cycle is completed. The number of cycle iterations, and therefore the test time, is variable. This test method is also often referred to as cyclic corrosion testing.
Cyclic corrosion testing aims to produce failures that are representative of conditions found in outdoor corrosive environments. These tests expose samples to a number of different environments in an iterative cycle. Simple exposures such as prohesion may consist of cycling between salt fog and dry conditions. Prohesion is a cyclic accelerated corrosion test method. This test is more closely related to prolonged natural exposure than conventional salt spray or moisture/sulfur dioxide tests.
Our organization also provides accelerated cyclic corrosion test services within the scope of Volvo VCS 1027, 1449 standard, with its trained and expert staff and advanced technological equipment, among the numerous test, measurement, analysis and evaluation studies it provides for businesses in various sectors.
