In particular the different approval criteria needed for the different types of ISO documents should be noted. Welding procedure specification Arc welding. The direction of magnetization with respect to the orientation of the weld shall be specified.

Search all products by. NOTE It can be necessary to perform an overall performance test of the system sensitivity for each specific procedure enn site. Magnetic particle testing Status: When using yokes or prods, there will be an area of the component in the vicinity of each pole piece or tip that will be impossible to test due to excessive magnetic field strength.

The performance test shall be designed to ensure a eb functioning of the entire chain of parameters including the equipment, the magnetic field strength and direction, surface characteristics, detection media and illumination. Variations in the basic techniques that will provide a higher or lower test sensitivity are described in Annex A.

This is usually seen as furring of particles. Learn more about the cookies we use and how to change your settings.

Each member body interested in a subject for which bw technical committee has been established has uso right to be represented on that committee.


Depending on the material being tested, its surface condition and magnetic permeability, indications will normally remain on the surface even after removal of the magnetic field due to residual magnetism within the part mainly at the location of the poles.

Where these are not available, fabricated test pieces with artificial imperfections or flux shunting indicators of the cross or disc or shim-type may be used.

This will prevent any indications being washed away. You may experience issues viewing this site in Internet Explorer 9, 10 or This can be achieved using one or more magnetization methods.

Thank you for interesting in our services. Magnetic particle testing often creates high magnetic fields close to the object under test and the magnetising equipment. Any cleaning or surface preparation shall not be detrimental to the material, the surface finish or the magnetic testing media.
