Comprehensive Guide to ASTM G50 Evaluation of Corrosion in Aqueous Media Laboratory Testing Service by Eurolab

ASTM G50 is a widely recognized standard for evaluating corrosion in aqueous media, developed by the American Society for Testing and Materials (ASTM). This standard provides a framework for conducting laboratory tests to assess the corrosiveness of various substances on materials. The standard has undergone several revisions since its inception, with the latest version being ASTM G50-18.

Legal and Regulatory Framework

The legal and regulatory framework surrounding ASTM G50 testing is governed by various national and international standards. These include:

  • ISO 15523:2006(E), Corrosion tests in artificial atmospheres - Determination of corrosivity in laboratory atmosphere

  • EN ISO 9223, Corrosion tests in artificial atmospheres - Corrosivity categories (C1 to C5) of substances in contact with metals

  • TSE (Turkish Standards Institution) IEC/EN 60529, Protection against corrosion by moisture

    • Standard Development Organizations and Their Role

    The development and maintenance of standards like ASTM G50 are the responsibility of standard development organizations. These organizations include:
