I. Product Introduction:    

Salt spray test chamber is a device that simulates a diffused system composed of tiny salt-containing droplets in the atmosphere, used to evaluate the corrosion resistance of products after various surface treatments such as painting, coating, electroplating, cathodic treatment, and rust prevention oil. Widely used.

Salt spray corrosion testing for electronics, electrical appliances, automobiles, motorcycles, hardware, plastics, FPC flexible circuit boards, electroplating products, etc.

II. Product Specifications:

The following meet the execution standards:

█Salt Spray Test Chamber's Equipment Technical Standard

Manufacturing, performance, safety, and calibration requirements for salt spray test chambers ensure that equipment produced by different manufacturers operates under uniform and reliable conditions. The core purpose is to guarantee the repeatability and comparability of test results.

Primary international/National equipment standards include:

1、GB/T 10587-2006"Salt Spray Test Chamber Technical Conditions"

· This is the Chinese National Standard, which is an authoritative technical specification for the salt spray test chamber equipment itself. It specifies in detail the structure, materials, temperature uniformity, sedimentation amount, and salt spray particle size, among other key technical parameters.

2、IEC 60068-2-11Environmental Testing2-11Partial: TestKaSalt雾

· The International Electrotechnical Commission standards, while primarily a test method standard, the requirements for the testing equipment (salt spray cabinet) are also widely regarded as the design and verification benchmark for the equipment.

3、ASTM B117 - Standard Practice for Operating Salt Spray (Fog) Apparatus

· The American Society for Testing and Materials (ASTM) standard, which is the most widely used salt spray test method globally. It clearly specifies the requirements for the structure, spray system, and temperature control of the salt spray cabinet in the "Equipment" section, serving as a guideline that equipment manufacturers must adhere to.

4、ISO 9227Artificial Atmosphere Corrosion Test - Salt Spray Test

ISO standards, withASTM B117Similarly, it serves as both a method standard and includes detailed equipment specifications. Commonly used in European and many international projects.

█Standard Test Method in Salt雾 Cabinet

These standards specify how to conduct specific corrosion tests, including sample preparation, solution preparation, test duration, and result evaluation. Users choose different testing methods based on the industry and purpose of their product.

Common types of salt spray tests and corresponding standards:

1Neutral Salt Spray Test

· Standard Number:ASTM B117, ISO 9227-NSS, GB/T 10125-2021

· Features: Most fundamental and commonly used tests.5%Sodium chloride solutionpHValue adjusted to neutral6.5~7.2), Test temperature is generally35°C。

· Application: Widely used for rapid corrosion resistance identification of metals and their alloys, metal coatings, organic coatings, etc.

2Acetate Mist Test

· Standard Number:ISO 9227-AASS, ASTM G85-Annex A1, GB/T 10125-2021

· Features: FeaturingNSSBased on testing, by adding glacial acetic acid to the collected liquid,pHThe value is reduced to approximately3.1~3.3Corrosion rate compared toNSSTesting is faster.

· Application: Primarily used for copper+Nickel+Chrome or Nickel+Chromium and other decorative coatings are also used in accelerated corrosion tests for aluminum alloys.

3Copper Accelerated Acetate Fume Test

· Standard Number:ISO 9227-CASS, ASTM B368, GB/T 10125-2021

· Features: As followsAASSOn the basis of the test, copper chloride is then added to further accelerate corrosion. The test temperature is generally...50°CThis is the fastest corroding in all salt spray tests.

· Application: Primarily used for copper+Nickel+Chrome or Nickel Plating+The chrome plating undergoes rapid, stringent quality inspections.

4Cyclic Corrosion Test

· This is a more advanced testing concept, encompassing not only salt spray but also stages like drying, wetting, and condensation, more accurately simulating the wet and dry cycles of the natural environment.

· Common Standards:

Automotive Industry:SAE J2333, GM 9540P, VOLVO VCS 1027,1491, Ford CETP 00.00-L-467

· General Standards:ASTM G85, ISO 11997-1, GB/T 20853 / 20854China Standard for Metal Coating Cyclic Corrosion Test

· The correlation between the cyclic test results and the actual outdoor corrosion is much better than that of the traditional continuous salt spray test.
