Overview
EN ISO 9934-3:2015 (Non-destructive testing - Magnetic particle testing - Part 3: Equipment) defines equipment requirements and verification methods for magnetic particle testing (MPT). Published by CEN/ISO, this part of the ISO 9934 series covers the types of equipment used for magnetizing, demagnetizing, illumination, measurement and monitoring of MPT processes. It sets out the properties suppliers must provide, minimum application requirements, and methods for measuring key parameters, including calibration and in-service checks where applicable.
Key topics and technical requirements
- Types of equipment: portable/transportable devices (hand-held electromagnets or yokes), fixed installations (benches, coils), and specialized testing systems (continuous process lines with sequential stations).
- Magnetizing and demagnetizing equipment: specifications for current generators, electromagnets and demagnetizers required to produce repeatable magnetic fields and to remove residual magnetization.
- Illumination and UV-A sources: requirements for viewing conditions and UV-A lighting used with fluorescent detection media.
- Detection media systems: guidance on systems that deliver magnetic particle suspensions or dry powders and related handling/monitoring.
- Inspection booths and ergonomics: enclosure, safety and viewing condition recommendations for reliable inspections.
- Measurements and calibration: procedures for current measurement, magnetic field measurement, viewing condition checks, verification and calibration of instruments and in-service inspections.
- Safety and compliance: equipment design must take into account applicable international, regional and national health, electrical and environmental regulations.
Keywords: EN ISO 9934-3:2015, magnetic particle testing equipment, non-destructive testing, MPT calibration, UV-A sources.
Practical applications and users
EN ISO 9934-3:2015 is used to:
- Specify procurement requirements for MPT equipment (manufacturers and purchasers).
- Establish acceptance tests, calibration routines and in-service checks for NDT labs.
- Design and validate fixed inspection stations and continuous testing process lines in manufacturing and heat-treatment plants.
- Set requirements for portable field inspection tools used by maintenance and quality teams.
Typical users:
- NDT engineers and inspectors
- Equipment manufacturers and suppliers
- Quality managers and compliance officers
- Fabricators, foundries and forging plants
- Testing laboratories and process integrators
