Salt Spray Chamber

Product catalog summary
Overview: The Salt Spray Chamber is a widely used tool for conducting corrosion tests on various metal parts. It is primarily used to assess the corrosion resistance of materials and surface coatings, including metals, stones, ceramics, and polymers.
Purpose: The test is designed to simulate a corrosive environment to evaluate the effectiveness of protective coatings. The duration of the test correlates with the corrosion resistance of the coating; more resistant coatings require longer testing periods before showing signs of corrosion.
Test Standards: The document references several standards, including ISO 9227, ASTM B117, and ASTM G85, which outline procedures for different types of salt spray tests such as Neutral Salt Spray (NSS), Acetic Acid Salt Spray (AASS), and Copper-Accelerated Acetic Acid Salt Spray (CASS).
Test Methods:
  • 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. It involves exposing specimens to an acetic acid salt spray at 35°C, with a pH of 3.1–3.3, under steady conditions.
  • ASTM G85 Acidified Salt Fog Test (Cyclic): This test assesses the corrosion resistance of aluminum alloys through a cyclic process involving acetic acid salt spray, air drying, and high humidity exposure at 49°C. The cycle includes 0.75 hours of salt spray, 2 hours of air drying, and 3.25 hours of high humidity.
Equipment: The document mentions specific models of Haida Machine's Salt Spray Testers, including HD-E808-90, HD-E808-160, and HD-E808-3600, which are designed for different testing needs.

Salt Spray Chamber-1

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.

Salt Spray Chamber-2

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...
