Comprehensive Guide to ISO 9934 Magnetic Particle Testing Laboratory Testing Service Provided by Eurolab
ISO 9934 is an international standard for the non-destructive testing of ferromagnetic materials using magnetic particle testing (MPT). This standard provides guidelines for the calibration, certification, and performance evaluation of MPT equipment, as well as the procedures for conducting MPT tests. The standard is widely used in various industries, including aerospace, automotive, oil and gas, and energy.

ISO 9934-2:2015(E) - Non-destructive testing of ferromagnetic materials - Magnetic particle testing - Part 2: Determination of the depth of penetration
ASTM E1444-13 - Standard Practice for Liquid Penetrant Testing
EN ISO 9934-1:2015 - Non-destructive testing of ferromagnetic materials - Magnetic particle testing - Part 1: Location and sizing of discontinuities
EN ISO 9934-2:2015 - Non-destructive testing of ferromagnetic materials - Magnetic particle testing - Part 2: Determination of the depth of penetration
TSE (Turkish Standards Institution) standards for MPT are based on international standards, including ISO 9934 and ASTM E1444.
Standard Development Organizations
The International Organization for Standardization (ISO) is responsible for developing and publishing international standards. The American Society for Testing and Materials (ASTM) develops and publishes standards in the United States. Other standard development organizations include the European Committee for Standardization (CEN), the Turkish Standards Institution (TSE), and industry-specific associations such as the American Petroleum Institute (API).
Standard Evolution
Standards evolve over time to reflect new technologies, methods, and practices. ISO 9934-1:2015(E) and ISO 9934-2:2015(E) supersede earlier versions of the standard. Standards development is an ongoing process that involves input from experts, industry stakeholders, and regulatory bodies.
