ASTM G85 Annex A5 SO2 Salt Fog Test Laboratory Testing Service: A Comprehensive Guide

The ASTM G85 Annex A5 SO2 Salt Fog Test is a laboratory test used to assess the corrosion resistance of materials and coatings in a simulated salt fog environment. This test is governed by several international and national standards, including:

  • ISO 9223: Corrosion tests in artificial atmospheres - Rating system for the measurement of corrosivity

  • ASTM G85: Salt Spray (Fog) Testing

  • EN ISO 9227: Corrosion tests in artificial atmospheres - Sodium chloride solution

  • TSE (Turkish Standards Institution): Corrosion tests in artificial atmospheres

    • These standards are developed and published by standard development organizations such as the American Society for Testing and Materials (ASTM), International Organization for Standardization (ISO), and European Committee for Standardization (CEN). These organizations play a crucial role in ensuring that standards evolve and get updated to reflect changes in technology, industry practices, and regulatory requirements.

    The international and national standards that apply to this specific laboratory test are:

  • ISO 9223: Corrosion tests in artificial atmospheres - Rating system for the measurement of corrosivity

  • ASTM G85: Salt Spray (Fog) Testing

    • These standards specify the testing conditions, equipment, and procedures required to conduct the SO2 Salt Fog Test. They also provide guidelines for interpreting test results and determining the corrosion resistance of materials and coatings.

    The SO2 Salt Fog Test is a critical component of various industries, including:

  • Aerospace

  • Automotive

  • Construction

  • Marine

  • Oil and Gas

    • These industries require this testing to ensure that materials and coatings can withstand exposure to corrosive environments. Failure to perform this test can result in equipment failure, reduced product lifespan, and increased maintenance costs.

    The SO2 Salt Fog Test is required for various reasons:

  • Business Reasons: To ensure compliance with regulatory requirements and industry standards

  • Technical Reasons: To evaluate the corrosion resistance of materials and coatings in a simulated salt fog environment

  • Consequences of Non-Compliance: Failure to perform this test can result in equipment failure, reduced product lifespan, and increased maintenance costs

    • The SO2 Salt Fog Test is essential for industries that require high-quality products and equipment that can withstand corrosive environments. This testing provides confidence in the performance and durability of materials and coatings.

    The SO2 Salt Fog Test involves the following steps:

    1. Sample Preparation: The test samples are prepared according to the relevant standard, usually by cleaning, drying, and weighing them.

    2. Testing Equipment: The testing equipment includes a salt fog chamber, a heating system, a cooling system, and a data acquisition system.

    3. Testing Environment: The testing environment is controlled at specific temperatures (25C or 35C) and humidity levels (50 or 95).

    4. Sample Exposure: The test samples are exposed to the SO2 salt fog environment for a specified period (usually 240 hours).

    5. Measurement and Analysis: The corrosion products formed on the surface of the test samples are measured using various techniques, such as weight gain, electrochemical impedance spectroscopy, and scanning electron microscopy.

    The testing equipment used in this test includes:

  • Salt fog chamber

  • Heating system

  • Cooling system

  • Data acquisition system

    • The testing environment requirements include:

  • Temperature: 25C or 35C

  • Humidity: 50 or 95

  • Pressure: atmospheric pressure

    • The test results are documented and reported according to the relevant standard. The report format includes:

  • Test conditions

  • Sample preparation details

  • Testing equipment used

  • Measurement and analysis methods

  • Results interpretation

    • The certification and accreditation aspects include:
