Product Description

The artificial atmosphere corrosion test chamber has always been one of the flagship products of Wuhu Environmental Testing, a leader in the industry, and has continued to develop other types of corrosion testing equipment.Salt spray corrosion test chamber, composite (alternating) corrosion test chamber, mixed gas corrosion test chamber, sulfur dioxide salt spray test chamber, carbide salt spray test chamber, hydrogen sulfide corrosion test chamber, periodic immersion corrosion test chamber

This equipment is widely used in enterprises and institutions such as electrical and electronic engineering, aerospace, automobiles and motorcycles, military equipment and weapons, electrical and electronic engineering, chemical metallurgy, quality inspection and measurement, postal and telecommunications, ships and railways, as well as universities, colleges and research institutions.

This device is designed to simulate weather conditions and marine climate, and is used for testing the protective layer of products and other products in a simulated salt spray environment; It is the use of salt containing solutions or acidic salt containing solutions to accelerate the corrosion of materials or products in a certain temperature and relative humidity environment, testing the degree of damage suffered by materials or products within a certain time range.

Reference standards

Artificial atmosphere corrosion test chamberStrictly follow the national military salt spray test standard GJB 150.11 and the standard GB 2423.17 for salt spray testing of electrical and electronic products that I have issued;

Meet the salt spray test standards GB 6458, GB 6459, and GB6460 for use in covering layers;

Meet the salt spray test standards GB 5938, GB 5939, and GB 5940 for assessing electroplated coatings on light industrial products;

Meet the salt spray test standard GB 1771 applicable to paint layers and other standards currently in use internationally regarding salt spray corrosion.

Artificial atmosphere corrosion test chamberThe salt spray test has been adopted as the home standard and detailed regulations have been provided. It has evolved from the initial simple neutral salt spray test to various forms such as acetic acid salt spray test, copper salt accelerated acetic acid salt spray test, and alternating salt spray test.

satisfytest method：Cover layer, neutral salt spray test (NSS test)

A salt solution is prepared using sodium chloride (chemically pure, analytical pure) and distilled or deionized water, with a concentration of (5% ± 0.1) (mass percentage). The collected liquid after atomization shall not be reused except for the blocking part of the baffle;

b. The pH value of the salt solution before atomization is between 6.5 and 7.2 (35 ± 2 ℃). When preparing a salt solution, a chemically pure dilute hydrochloric acid or sodium hydroxide solution can be used to adjust the pH value, but the concentration still needs to meet the requirements of point a.

• Belonging to the covering layer, copper accelerated acetate salt spray test (CASS test)
  • Dissolve sodium chloride in distilled or deionized water at a concentration of 5%, which is 50 ± 5g/L.
  • Add copper chloride (CuC1) to solution a₂·2H₂O）, Its concentration is 0.26 ± 0.02g/L (i.e. 0.205 ± 0.015g/L anhydrous copper chloride).
  • Add an appropriate amount of glacial acetic acid to the solution to ensure that the pH value of the salt spray collection solution in the test chamber is between 3.1 and 3.3. If the pH value of the solution before spray is 3.0~3.1, the pH value of the collected solution is generally in the range of 3.1~3.3. The pH value of a solution can be measured using an acidimeter, or a precise pH test strip calibrated with an acidimeter that can read a 0.1 pH value change can be used for daily testing. The pH value of the solution can be adjusted using glacial acetic acid or sodium hydroxide.
  • To avoid nozzle clogging, the solution must be filtered before use.

Note: Belonging to the covering layer, the acetate salt spray test (ASS test) is omitted in the "B" process”b”Step by step.
