About exposure testing
Exposure testing is typically performed for purposes of material selection, quality control, CLP-directive, ….
In an exposure test a coupon (test plate) of the material to be examined (metal, coated metal, plastic) is exposed to standardized or non-standardized conditions. The exposure time varies between several weeks to months.
Depending on the situation, you can choose to mimic real environmental conditions as closely as possible. Alternatively, you can apply worst-case scenarios or use standardized conditions. These approaches help qualify the material for its intended application.
Exposure testing parameters:
Some of the parameters that need to be considered are:
- Material (surface condition, presence of a weld, …)
- Medium
- Phase (liquid, interphase, gas)
- Aeration
- Temperature/pressure
- Agitation
Broad range of testing possibilities and standards
Our well-equipped laboratory performs all classical exposure tests, as well as simulations and pilot-scale tests tailored to the customer’s needs.
Here are some of the tests and corresponding standards we offer, though this list is not exhaustive.
- Exposure tests to determine degradation phenomena and (localized) corrosion rate in liquid phase/intherphase/ gas phase – ASTM G31
- Testing of crevice corrosion – ASTM G78
- Testing of stress-corrosion cracking (among others ‘drop evaporation test (DET)’)
- Testing of galvanic (contact) corrosion
- Testing of atmospheric corrosion (by salt spray tests, cyclic corrosion tests, condensation tests, climate tests) – ISO 9227, ASTM B117, Kesternich test, …
- Tests to evaluate corrosion under insulation (CUI) – ASTM G189, ASTM C795, ASTM C1617
- Tests according to ADR legislation (CLP-directive)
- Quality control tests like Huey, Streicher and Strauss tests – ASTM A262
- Tests to evaluate corrosion inhibitors
