Standard Practice for
Magnetic Particle Testing1
This standard is issued under the ﬁxed designation E 1444; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A superscript epsilon (e) indicates an editorialchange since the last revision or reapproval. This standard has been approved for use by agencies of the Department of Defense.
1. Scope 1.1 This practice establishes minimum requirements for magnetic particle examination used for the detection of surface or slightly subsurface discontinuities in ferromagnetic material. Guide E 709 can be used in conjunction with this practice as a tutorial.NOTE 1—This Practice replaces MIL-STD-1949.
1.2 The magnetic particle examination method is used to detect cracks, laps, seams, inclusions, and other discontinuities on or near the surface of ferromagnetic materials. Magnetic particle examination may be applied to raw material, billets, ﬁnished and semi-ﬁnished materials, welds, and in-service parts. Magnetic particle examination is not applicableto non-ferromagnetic metals and alloys such as austenitic stainless steels. See Appendix X6 for additional information. 1.3 All areas of this Practice may be open to agreement between the Cognizant Engineering Organization and the supplier, or speciﬁc direction from the Cognizant Engineering Organization. 1.4 This standard does not purport to address all of the safety concerns, if any, associatedwith its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. 2.
