Introduction

GB/T 2423.17-2024 Salt Spray Test Standard Interpretation

Salt spray test is a classic method widely used to evaluate the corrosion resistance of electrical products, components and materials. This article will deeply analyze the GB/T 2423.17-2024 standard, covering its technical background, updated content, implementation points and comparison with international standards.

Comparison of standard frameworks

Dimensions Old version of the standard (GB/T 2423.17-2008) New version of the standard (GB/T 2423.17-2024)
Scope of application Only applicable to corrosion resistance test of metal materials Extended to include coatings, anodized films and other materials
Test solution concentration 50 g/L ±10 g/L 50 g/L ±5 g/L, improved accuracy
pH range No specific requirements are specified 6.5-7.2 (adjusted to be more stringent)

Technical background and evolution analysis of salt spray test

Salt spray test originated in the 19th century and was originally used to evaluate the corrosion resistance of marine equipment. With the development of science and technology, this method has gradually been applied to many fields such as electrical products and automotive parts.

GB/T 2423.17 standard has undergone three revisions since its first release in 1981:

  • 1981: The basic framework and methods of salt spray test were established for the first time.
  • 1993: The first revision included more material types.
  • 2008: The second revision refined the test conditions and requirements.
  • 2024: The third revision will be in line with the international standard IEC 60068-2-11 to improve the level of standardization.

Implementation recommendations and precautions

Laboratory setup: Ensure that the test equipment is made of inert materials to avoid secondary corrosion. It is recommended to use a standardized file structure that meets the requirements of GB/T 1.1-2020.

Equipment calibration: Regularly verify the accuracy of the salt spray generator and pH measuring instrument, recommended at least once a year.

Data recording: It is recommended to use a digital recording system to ensure the traceability of test conditions, duration and results.
