Salt Spray Chamber

Product catalog summary

Overview: The Salt Spray Chamber is a widely used tool for conducting corrosion tests on various metal spare parts. It is primarily used to assess the corrosion resistance of materials and surface coatings, including metallic, stone, ceramics, and polymers.

Application Range: The chamber is used to evaluate the effectiveness of surface coatings intended to protect underlying metals from corrosion. The test is applicable to a wide range of materials, including those with permanent or temporary corrosion protection.

Determination: Salt spray testing is an accelerated corrosion test that subjects coated samples to a corrosive environment to evaluate the coating's protective capabilities. The duration of the test varies based on the corrosion resistance of the coating, with more resistant coatings requiring longer testing periods.

Test Standards: The testing adheres to several standards, including ISO 9227, ASTM B117, ASTM G85, ISO 3769, ISO 3770, ASTM B268, JIS D0201, JIS H8502, and JIS Z2371.

ISO 9227: This standard outlines the procedures for neutral salt spray (NSS), acetic acid salt spray (AASS), and copper-accelerated acetic acid salt spray (CASS) tests to assess the corrosion resistance of metallic materials.

ASTM G85 Acetic Acid Salt Spray Test (Non-Cyclic): This test evaluates the corrosion resistance of decorative chromium plating on steel and zinc-based die casting in an acetic acid salt spray environment at 35°C. The test involves a continuous indirect spray of salt water solution acidified to a pH of 3.1–3.3.

ASTM G85 Acidified Salt Fog Test (Cyclic): This test assesses the corrosion resistance of aluminum alloys in a cyclic environment involving acetic acid salt spray, air drying, and high humidity at 49°C. The test cycle includes 0.75 hours of salt spray, 2 hours of air drying, and 3.25 hours of high humidity exposure.

Equipment: The document references specific models of Haida Machine's corrosion salt spray testers, including HD-E808-90, HD-E808-160, HD-E808-3600, and HD-E808-90C, which are designed for ASTM G85 cyclic salt spray testing.

Catalog excerpts

Salt Spray Chamber Salt Spray Tester (Or salt fog test) is a pretty common corrosion test for various metal spare part. Application range: usually used to check corrosion resistance of materials and surface coatings. And the materials range cover metallic (although stone, ceramics, and polymers may also be tested) and finished with a surface coating which is intended to provide a degree of corrosion protection to the underlying metal. Determination: Salt spray testing is an accelerated corrosion test that produces a corrosive attack to coated samples in order to evaluate the suitability of the coating for use as a protective finish. The appearance of corrosion products is evaluated after a pre-determined period of time. Test duration depends on the corrosion resistance of the coating; generally, the more corrosion resistant the coating is, the longer the period of testing before the appearance of corrosion or rust. Test Standard: ISO 9227, ASTM B117, ASTMG85, ISO:3769, ISO3770, ASTM B268, JIS: D0201, JIS H8502, JIS Z2371 Test Standard Explanation ISO 9227 This standard indicate the test items for neutral salt spray (NSS), acetic acid salt spray (AASS) and copper-accelerated acetic acid salt spray (CASS) tests for assessment of the corrosion resistance of metallic materials, with or without permanent or temporary corrosion protection.

ASTM G85 Acetic Acid Salt Spray Test (non-cyclic) This can be used to determine the relative resistance to corrosion of decorative chromium plating on steel and zinc based die casting when exposed to an acetic acid salt spray climate at an elevated temperature. This test is also referred to as an ASS test. Test specimens are placed in an enclosed chamber and exposed to a continuous indirect spray of salt water solution, prepared in accordance with the requirements of the test standard and acidified (pH 3.1–3.3) by the addition of acetic acid. This spray is set to fall-out on to the specimens...
