Salt Spray Test Machine

The Salt Spray Tester is used to create and maintain the salt spray (fog) test environment, and test the anti-corrosion quality of all the materials surfaces after the rust-proof of painting, coating, electroplating, anodizing and rust-proof of greasing. Our salt spray testers available in two capacities meet ASTM-B117. JIS-D0201. JIS-H8502. JIS-H8610. JIS-Z2371 and other International Standards test methods. Power supplied can be configured upon request.

Application：

Salt spray chamber is an international certification standardization and popular corrosion test method for checking the corrosion resistance of materials and surface coatings.

salt spray chamber is the inexpensive, fastest, standard and repeatable ,mainly used to detect salt spray corrosion resistance of the material or material surface coating which often in corrosive environment . The HD salt spray chamber is equipped with an intelligent salt spray test system that enables quick and standardized conversion of test modules. Automatically adjust the test temperature in the workpeace (Salt Spray Method (NSS ACSS) 35 ± 1 ° C, Corrosion-resistant Testing Method (CASS) 50 ± 1 ° C).

Feature：

1. The whole system using PVC plate, lined with the use of advanced three-dimensional reinforcement ring technology, structure and strong real, never deformation.

2. Five direction heating system to ensure heat distribution within ±1oC.

3. Highly advanced spray nozzle with accuracy of spray misting within ±0.3ml/80cm2.

4. Saturated air with Henry's law. In order to heated humidification, and provided the necessary laboratory humidity.

5. Temperature control uses P.I.D temperature controller within ±0.3oC accuracy.

6. The only use of early warning device test solution is too low, when the test solution is only enough for 5 hours and then spray the buzzer supplement will notify the user to ensure that the test of the value of the continuous spray.

7. The only use the full detection system, when a failure occurs, you can display or alarm lights inform.

8. With a spray and standing time period setting (for CAPA, SAE, ASTM).

9. Meets ASTM B117-03 the new improved design.

FAQs

Q. What is salt spray test?

A. The salt spray test is a standardized test method used to check corrosion resistance of coated samples. Coatings provide corrosion resistance to metallic parts made of steel, zamak or brass. Since coatings can provide a high corrosion resistance through the intended life of the part in use, it is necessary to check corrosion resistance by other means. Salt spray test is an accelerated corrosion test that produces a corrosive attack to the coated samples in order to predict its suitability in use as a protective finish. The appearance of corrosion products (oxides) is evaluated after a period of time. Test duration depends on the corrosion resistance of the coating; the more corrosion resistant the coating is, the longer the period in testing without showing signs of corrosion.

Q. What’s the most common testing standards of salt spray test?

A. ISO 9227, EN 1670, JIS Z 2371, DIN 50021, ASTM B 117, NEMA250, UL 50E, ASTM G 85, ASTM B 368, ASTM D 5894, IEC 60068-2-52 Part 2, SAE J2334 and more.

Q.Types of Salt Spray Tests?

1. Neutral Salt Spray (NSS)

Most common test type

Uses neutral pH (6.5–7.2) sodium chloride solution

Standard for evaluating corrosion resistance of painted or coated metals

2. Acetic Acid Salt Spray (AASS)

Uses acidic solution (pH ~3.1–3.3)

Accelerates corrosion, especially for zinc coatings

Common in automotive and galvanization testing

3. Copper Accelerated Acetic Acid Salt Spray (CASS)

Contains copper chloride and acetic acid

Highly aggressive test for plated metals

Evaluates protective coatings in harsh conditions

Q. What should I prepare before choosing a salt spray chamber?

A. Firstly, define which products will be tested, list all of the weights and sizes? Secondly, confirm which standards do your tests must comply with? Thirdly, choose the right models of salt spray chambers, make sure it’s functions could meet your testing requirements(standards, weights, sizes and quantity). Fourthly, choose a good brand.

Q. What is a typical salt spray tests procedure?

A. Step 1, Setup salt spray chamber. Step 2, Prepare test specimens. Step 3, Prepare testing solution. Step 4, Position test specimens and run test.

Q.How Long Does Salt Spray Testing Take?

Salt spray testing duration depends on the material and coating type:

Mild steel: 24–48 hours to see corrosion

Coated metals: 96–500+ hours depending on coating quality

High-performance coatings: up to 1000 hours for automotive or aerospace

Tip: Testing should be aligned with the intended standard for accurate benchmarking.
