Introduction to salt spray corrosion resistance testing
If a product comes into contact with oxidizing agents, a test chamber for salt spray can help to verify the corrosion resistance. The salt spray corrosion resistance test can be carried out in accordance with following standards:
- EN 9227 “Corrosion tests in artificial atmospheres – Salt spray test”
- ASTM B 117 “Standard Practice for Operating Salt Spray (Fog) Apparatus”
- CEI EN 60068-2-11 “Environmental testing – Tests- Test Ka: salt spray”
- CEI EN 60068-2-11 “Environmental testing – Tests- Test Kb: salt spray, cyclic”
- EN 248 “Sanitary tapware – General specification for electrodeposited coatings Ni-Cr”
- RTCA/DO 160 “Environmental conditions and test procedures for airbone equipment – Salt fog”
- MIL-STD-202-G “Department of Defence – Test method standard – Electronic and electrical component parts”
- And other particular specifications
The analysis of the test results can be carried out in accordance with EN ISO 10289 “Methods for corrosion testing of metallic and other inorganic coatings on metallic substrates – Rating of test specimens and manufactured articles subjected to corrosion tests” or with customers’ specifications
Main equipment used during salt spray corrosion resistance tests
Tests are carried out in corrosion chambers where we recreate the conditions that trigger the corrosion process, following the main international standards.
Thanks to salt spray resistance tests it is possible to obtain the necessary results to request the certification to European institutions.
Salt spray tests can help the manufacturer to determine how corrosion may affect his product and which is the best coating or which materials may be the best suitable for a particular application field.
