Comprehensive Guide to ISO 7539-9 Testing of Stainless Steel Corrosion: A Laboratory Testing Service Provided by Eurolab

ISO 7539-9 is an international standard that governs the testing of stainless steel corrosion. This standard is developed and published by the International Organization for Standardization (ISO) in collaboration with various national standards organizations, such as ASTM International (American Society for Testing and Materials), EN (European Committee for Standardization), TSE (Turkish Standards Institution), and others.

Legal and Regulatory Framework

The testing of stainless steel corrosion is regulated by various laws and regulations across different countries. For instance:

  • In the European Union, the Corrosion Protection of Steel Products Directive (89/106/EEC) requires that all steel products must meet certain minimum standards for corrosion resistance.
  • In the United States, the American Society for Testing and Materials (ASTM) develops and publishes standards for testing stainless steel corrosion, which are adopted by various industries and regulatory agencies.
  • In Turkey, the Turkish Standards Institution (TSE) has developed a national standard for testing stainless steel corrosion, which is used in conjunction with ISO 7539-9.
  • International and National Standards

    The following international and national standards apply to ISO 7539-9 Testing of Stainless Steel Corrosion:

  • ISO 7539-9:2017 - Corrosion tests in artificial atmospheres - Accelerated corrosion test on stainless steel strip using a bending method
  • ASTM G4-13 - Standard Practice for Conducting Salt Spray (Fog) Tests
  • EN ISO 3651-2:2000 - Corrosion of metals and alloys Accelerated corrosion tests by alternating dipping (withdrawal) in acid or salt solutions
  • TSE 7095:2013 - Testing methods for steel products - Part 9: Corrosion resistance
  • Standard Development Organizations

    The development of ISO 7539-9 involves the collaboration of various standard development organizations, including:

  • ISO (International Organization for Standardization)
  • ASTM International (American Society for Testing and Materials)
  • EN (European Committee for Standardization)
  • TSE (Turkish Standards Institution)
  • These organizations work together to develop and publish standards that are widely adopted by industries and regulatory agencies.

    Standard Evolution and Updates

    Standards evolve over time as new technologies, materials, and testing methods become available. For instance:

  • ISO 7539-9 was first published in 1997 and has undergone several revisions since then.
  • The current version of the standard (ISO 7539-9:2017) includes updates to the test method, sampling procedure, and interpretation of results.
  • Standard Compliance Requirements

    Compliance with ISO 7539-9 is required for various industries, including:

  • Construction
  • Automotive
  • Aerospace
  • Chemical processing
  • Failure to comply with this standard can result in product rejection, recalls, or even litigation.
