ASTM B117 Salt Spray Testing -Walk-in Temperature Humidity Integrated With Salt Spray Chamber

ASTM B117 is a salt spray test standard developed and published by the American Society for Testing and Materials (ASTM) Technical Committee on Standardization, and is an important test method for assessing the corrosion resistance of materials.

In daily production and use, the environment has a great impact on products, especially into the ocean and other humid environments, equipment and metal materials for a long time in this humid environment will face severe corrosion and oxidation problems.ASTM B117 is a salt spray test standard developed and published by the American Society for Testing and Materials (ASTM) Technical Committee on Standardization, and is an important test method for assessing the corrosion resistance of materials.

Standard Overview

ASTM B117 is a standard protocol for the operation of salt spray installations designed to simulate the corrosion risks to which metallic materials are exposed in marine environments, humid climates, and other conditions. The standard was developed by ASTM International to evaluate the corrosion resistance of metals and their coatings and to provide guidance on material selection and surface treatment techniques.

The ASTM B117 standard applies to salt spray resistance testing of any material, open or sealed, such as coatings, metal alloys, plastics, rubber, etc. The standard is designed to assess the corrosion resistance of materials. Through the salt spray test, the degree of corrosion resistance of a material can be assessed to determine its feasibility for adoption in marine environments or other harsh environments.

Test conditions and parameters

Temperature control: The test chamber needs to be maintained at 35°C (±2°C).

Salt spray solution: Use 35g of sodium chloride dissolved in one litre of deionised water.

pH Control: The pH of the salt spray solution should be maintained at 6.5 to 7.2.

Exposure time: usually 24 hours as a basic, with 96 hours, 240 hours and 600 hours as the most common evaluation lengths
