ISO 9934-3:2015 pdf free.Non-destructive testing一Magnetic particle testing一Equipment
This part of ISO 9934 describes three types of equipment for magnetic particle testing:
一portable or transportable equipment;
一fixed installations;
一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, ilumination, 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.
The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

The equipment design shall take into account all international, European, national and local regulations which include health, safety, electrical and environmental requirements.
Fixed installation benches can include facilities for current flow and magnetic flow techniques.Magnetic flow can be achieved either by an electromagnetic yoke or a fixed coil. The characteristics of the current generator are defined in 4.2.
When facilities for multidirectional magnetization are included, each circuit shall be independently controlled. Magnetization shall be sufficient to achieve the required detection capability in all directions.
The characteristic of the electromagnetic yoke is the tangential field strength, Ht, measured, in kiloamperes per metre, at the midpoint of the length of a cylindrical bar conforming to C22 (1.0402) of EN 10250-2, of specified dimensions (length and diameter) appropriate to the acceptance range of the equipment.
If the bench is to be used for magnetic flow testing of components longer than 1 m, or segments of the length are magnetized individually, the supplier shall define how magnetizing capability is determined.
This shall include a specification of the tangential field strength for a bar of suitable length and diameter.ISO 9934-3 pdf download.
