ASTM-D2803, 2009 - MADCADastm d2803 Significance and Use Some organic coatings applied to metal substrates exhibit filiform corrosion when there is a break in the coating film and the relative humidity is in the 70 to 95 % range.
Description of ASTM-D2803 2015 1.1 This guide covers three procedures for determining the susceptibility of organic-coated metal substrates to formation of filiform corrosion. 1.2 This guide is limited to the determination of whether filiform corrosion will occur between the organic coating and substrate. Accelerated Testing - HALOXFiliform Corrosion (ASTM D2803) Filiform Corrosion is a unique differential oxygen cell occurring on coated substrates. FFC leads to development of thin thread-like filaments full of corrosion products beneath the coating. It occurs on Aluminum, Steel, Magnesium and other metals. Color, Gloss, and Mechanical Testing |Q-LabFiliform Corrosion - ASTM D2803, ISO 4628-10 ; Color and Gloss Measurements. Instrumental measurements of appearance and surface characteristics include gloss, distinctness of image, and color. These are used in place of, or in addition to, the visual ratings. Electro-optical measurements are required by many standards, and provide the data
Corrosion Test Lab -environmental test chamber - ASTM, ASTM B117, ASTM B368, CASS, ASTM G85, GMW14872, GMW3172, SAE J2334, Ford CETP 00.00-L-467 Environmental Testing - Independent Test ServicesEnvironmental tests are conducted to examine and evaluate the behavior, propensity, and extent of resistance of certain materials to corrosive agents. Most tests feature an accelerated corrosion that produces a corrosive attack to coated samples in order to evaluate the suitability of the coating for use as a protective finish. Filiform Corrosion Testing - Applied Technical ServicesWe can identify filiform corrosion on metallic surfaces that are covered with an organic film. Based on the unique appearance of fine filament lines, the pattern of the corrosion can be characterized. We test filiform corrosion resistance of metals in compliance with ASTM D2803 and ISO 4623.
"ASTM D2803 tests specifically for filiform corrosion." Like salt spray, there are different high humidity testing options, but the two most common are ASTM D2803 and ASTM D2247. The former tests specifically for filiform corrosion, which is a type of crevice corrosion.
