Non-Destructive Testing

Non-destructive particle testing standards are published by ISO, AWS, SAE, and AS. ISO standards cover magnetic particle testing of welds, penetrant testing and magnetic particle testing, magnetic particle inspection of seamless and welded ferromagnetic steel tubes for the detection of surface imperfections, magnetic particle testing, and the NDT training syllabuses. The AWS standard covers the guide for nondestructive examination of welds. AS standards cover the glossary of terms and magnetic particle testing of ferromagnetic products, components, and structures. SAE covers carbon steel tubing for general use, exposure levels of UV radiation, and inspection standards for bolts and screws.

ISO 23278:2015

Non-destructive testing of welds - Magnetic particle testing - Acceptance levels

ISO 23278:2015 specifies acceptance levels for indications from imperfections in ferromagnetic steel welds detected by magnetic particle testing.

ISO 17638:2016

Non-destructive testing of welds - Magnetic particle testing

ISO 17638:2016 specifies techniques for detection of surface imperfections in welds in ferromagnetic materials, including the heat affected zones, by means of magnetic particle testing. The techniques are suitable for most welding processes and joint configurations. Variations in the basic techniques that will provide a higher or lower test sensitivity are described in Annex A. ISO 17638:2016 does not specify acceptance levels of the indications. Further information on acceptance levels for indications may be found in ISO 23278 or in product or application standards.

ISO 3059:2012

Non-destructive testing - Penetrant testing and magnetic particle testing - Viewing conditions

ISO 3059:2012 specifies the control of the viewing conditions for magnetic particle and penetrant testing. It includes minimum requirements for the illuminance and UV-A irradiance and their measurement. It is intended for use when the human eye is the primary detection aid. ISO 3059:2012 does not cover the use of actinic blue light sources.

ISO 10893-5:2011

Non-destructive testing of steel tubes - Part 5: Magnetic particle inspection of seamless and welded ferromagnetic steel tubes for the detection of surface imperfections

ISO 10893-5:2011 specifies requirements for magnetic particle inspection of seamless and welded ferromagnetic steel tubes for the detection of surface imperfections on the tube body and the end/bevel face at the ends. For the tube body, it specifies requirements for the detection of surface imperfections on all or part of the outside surface of tubes. However, by agreement between the purchaser and manufacturer, it can be applicable to the inside surface over a limited length from the ends of tubes, dependent on the tube diameter. In addition, ISO 10893-5:2011 can be used, as appropriate, to locate the position of external surface imperfections detected by another non-destructive testing method (e.g. ultrasonic) prior to dressing of the tube surface, and to ensure complete removal of the imperfection after dressing is complete. For the end/bevel face at the ends of plain-end and beveled-end tubes, ISO 10893-5:2010 specifies requirements for the detection of laminar imperfections which can interfere with subsequent fabrication and inspection operations (e.g. welding and ultrasonic inspection of the welds). ISO 10893-5:2011 is applicable to the detection of imperfections, other than laminar imperfections, on the end/bevel face. In this case, magnetization is applied in the direction essentially perpendicular to the orientation of the particular imperfections being detected. It can also be applicable to the testing of hollow sections.

ISO 9934-1:2016

Non-destructive testing - Magnetic particle testing - Part 1: General principles

ISO 9934-1:2016 specifies general principles for the magnetic particle testing of ferromagnetic materials. Magnetic particle testing is primarily applicable to the detection of surface-breaking discontinuities, particularly cracks. It can also detect discontinuities just below the surface but its sensitivity diminishes rapidly with depth. ISO 9934-1:2016 specifies the surface preparation of the part to be tested, magnetization techniques, requirements and application of the detection media, and the recording and interpretation of results. Acceptance criteria are not defined. Additional requirements for the magnetic particle testing of particular items are defined in product standards (see the relevant International Standards or European standards). ISO 9934-1:2016 does not apply to the residual magnetization method.

ISO 9934-2:2015

Non-destructive testing - Magnetic particle testing - Part 2: Detection media

ISO 9934-2:2015 specifies the significant properties of magnetic particle testing products (including magnetic ink, powder, carrier liquid, contrast aid paints) and the methods for checking their properties.

ISO 9934-3:2015

Non-destructive testing - Magnetic particle testing - Part 3: Equipment

ISO 9934-3:2015 describes three types of equipment for magnetic particle testing: - portable or transportable equipment; - fixed installations; - specialized testing systems for testing components on a continuous basis, comprising a series of processing stations placed in sequence to form a process line. Equipment for magnetizing, demagnetizing, illumination, measurement, and monitoring are also described. This part of ISO 9934 specifies the properties to be provided by the equipment supplier, minimum requirements for application and the method of measuring certain parameters. Where appropriate, measuring and calibration requirements and in-service checks are also specified.

ISO/TS 25107:2019

Non-destructive testing - NDT training syllabuses

This document gives requirements and recommendations for non-destructive testing (NDT) training syllabuses, with the intention of harmonizing and maintaining the general standard of training of NDT personnel for industrial needs. It also establishes the minimum requirements for effective structured training of NDT personnel to ensure eligibility for qualification examinations leading to third-party certification according to recognized standards. In addition to non-destructive testing in general, its guidelines for syllabuses cover acoustic emission testing, eddy current testing, leak testing, magnetic testing, penetrant testing, radiographic testing, ultrasonic testing, visual testing, thermographic testing, and strain gauge testing. ISO/TS 25108 gives requirements and recommendations for NDT training organizations.

SAE J 2592-2019

Carbon Steel Tubing for General Use, Understanding Nondestructive Testing for Carbon Steel Tubing

This Information Report describes eddy current testing, flux leakage testing, ultrasonic testing, and magnetic particle testing of steel tubing. The purpose of these testing methods is to expose flaws in the tube material or weld zone, such as discontinuities, seams, cracks, holes, voids, and other imperfections characteristic to the specific construction of the tubing. When agreed upon between the producer and purchaser, nondestructive testing is used in lieu of destructive hydrostatic pressure proof testing. Aircraft and Aerospace applications were not considered during the preparation of this document.

SAE AIR 4964-1998 (SAE AIR4964-1998)

Exposure Levels of UV Radiation in Nondestructive Inspection Processes ( Reaffirmed: Feb 2007 )

Long wave ultraviolet or UV-A radiation (between 320 to 400 nm) is used for fluorescent inspections in magnetic particle and liquid penetrant examinations. The UV-A radiation is obtained from either fluorescent or high intensity discharge lamps that are stationary or portable. The commercialy available UV-A lamps possess a large variation in intensity output that can cause a legitimate concern for possible health hazard. This draft reviews the nature of UV-A radiation emitted by these lights, blacklight equipment, acceptable UV dosage limits adopted by the American Conference of Governmental Industrial Hygienists (ACGIH) and the European Standards Committee for Nondestructive Testing, and recommendation of proper practices when working with UV-A radiation.
