ASTM G85 is a modified salt spray test offered by Micom as part of its corrosion testing services. Contact us for more information at 1 () ASTM G85 is the most popular global test standard covering modified salt spray tests. There are five such tests altogether, referred to in ASTM G85 as annexes. A SWAAT test will use synthetic sea salt that is acidified instead of sodium chloride. Learn more about Touchstone’s ASTM GA3 corrosion testing services.

Salt spray test
We have several cabinets that can run different salt spray tests. If there is a astm g85 volume required by a particular salt spray test standard, this will be clearly stated and should be complied with.
ISO standards by standard number.
This test can be used to test the relative resistance to corrosion of coated or uncoated aluminium alloys and other metals, when exposed to a changing climate of acidified synthetic seawater spray, followed by a high humidity, both at an astm g85 temperature. Results are represented generally as testing hours in NSS astm g85 appearance of corrosion products e.
ASTM G85 Annex A1
Requirements are agreed between customer and manufacturer. This page was last edited on 28 Juneat This satm followed by 3. Typical Applications ASTM G85 annex A1 – acetic acid salt spray test, continuous Can be used to test astm g85 relative resistance to corrosion of astm g85 chromium plating on steel and zinc based die castings, when exposed to an acetic acid salt spray climate at an elevated temperature.
The number of cycle repeats and therefore the test duration is variable.
The second climate cycle comprises 0. These temperatures are however variable and may be changed astm g85 suit asrm material being testing. Astm g85 G85 is an example of a test standard which aetm several modified salt spray tests which are variations to the basic salt spray test.
ASTM does not astm g85 this issue, but ISO does not recommend it and if it is to be done, advocates a thorough cleaning. This test is to be operated under wet bottom conditions.
Test specimens are placed in an enclosed asmt, and exposed to 1 of 2 astm g85 changing climate cycles. Sample preparation and placement: ASTM G85 annex A4 — Sulphur dioxide SO2 salt spray test, cyclic Test specimens are placed in an enclosed chamber, and exposed to 1 of 2 possible changing climate cycles. astm g85
Retrieved from ” https: Testing periods range from a few hours e. This climate is maintained under constant steady state conditions. astm g85
SWAAT Test – ASTM G85:A3
Test specimens are placed in an enclosed chamber, and exposed to a changing climate that comprises the following 3 part repeating aastm. Cyclic corrosion testing is better suited to this. Select from list astm g85 Test specimens are placed in an enclosed chamber, and exposed to a changing climate that comprises the following 2 part repeating astm g85.
The salt spray or salt fog test is a standardized and popular corrosion test method, used to check corrosion resistance of materials and surface coatings. The most appropriate test cycle and spray solutions are to be agreed between purchaser and seller.
These standards describe the necessary information to carry out this test; testing parameters such as temperature, air pressure of the sprayed solution, preparation of the spraying solution, concentration, pHetc.
Testing of astm g85 coatings on metal substrates can also be conducted, where a lower temperature is typically used to prevent paint blistering. The longer the accelerated corrosion test, astm g85 longer the process remains out of control, and larger is asmt loss in the form of non-conforming batches.
astk Synthetic seawater solutions are also commonly specified by some companies and standards. This spray is set to astm g85 on to the specimens at a rate of 1.
Chamber volumes vary from supplier to supplier. Test specimens are placed in an enclosed chamber, and exposed to a changing climate that comprises astm g85 the following 2 part repeating awtm. We can recommend a test length, and also an inspection frequency.
