|This practice establishes minimum requirements for magnetic
particle testing used for the detection of surface or slightly
subsurface discontinuities in ferromagnetic material. Guide E709
can be used in conjunction with this practice as a tutorial.
NOTE 1-This Practice replaces MIL-STD-1949.
The magnetic particle testing method is used to detect cracks,
laps, seams, inclusions, and other discontinuities on or near the
surface of ferromagnetic materials. Magnetic particle testing may
be applied to raw material, billets, finished and semi-finished
materials, welds, and in-service parts. Magnetic particle testing
is not applicable to non-ferromagnetic metals and alloys such as
austenitic stainless steels. See Appendix X1 for additional
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.
This standard is a combined standard, an ASTM standard in which
rationalized SI units and inch-pound units are included in the same
standard, with each system of units to be regarded separately as
Units-The values stated in either SI units or inchpound
units are to be regarded separately as standard. The values stated
in each system may not be exact equivalents; therefore, each system
shall be used independently of the other. Combining values from the
two systems may result in nonconformance with the standard.
This standard does not purport to address all of the safety
concerns, if any, associated with 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.
