BS EN ISO 9934-1:2015 pdf free.Non-Destructive Testing – Magnetic Particle Testing – Part1:General Principles.
BS EN ISO 9934-1 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 hut its sensitivity diminishes rapidly with depth.
BS EN ISO 9934-1 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 ISO or EN standards).
BS EN ISO 9934-1 does not apply to the residual magnetization method.

3 Terms and definitions
For the purposes of this document, the terms and definitions given in Iso 12707, EN 1330-1, EN 1330-2,and EN 1330-7 apply.
4 Qualification and certification of personnel
It is assumed that magnetic particle testing is performed by qualified and capable personnel. In order to provide this qualification, it is recommended to certify the personnel in accordance with ISO 9712 or equivalent.
5 Safety and environmental requirements
All international, European, national, and local regulations which include health, safety and environment shall be taken into account.
Magnetic particle testing often creates high magnetic fields close to the object under test and the magnetizing equipment. Items sensitive to these fields should be excluded from such areas.
6 Testing procedure
When required at the time of enquiry and order, magnetic particle testing shall be performed in accordance with a written procedure.
The procedure can take the form of a brief technique sheet, containing a reference to this and other appropriate standards. The procedure should specify testing parameters in sufficient detail for the test to be repeatable.
All testing shall be performed in accordance with an approved written procedure or the relevant product standard shall be referenced.BS EN ISO 9934-1:2015 pdf free download.
