ASTM E125-63(2003)

Standard Reference Photographs for Magnetic Particle Indications on Ferrous Castings

SCOPE
1.1 This collection of reference photographs covers types and degrees of discontinuities occurring in steel castings and other types of ferrous castings detectable by the dry powder magnetic particle method.
1.2 These reference photographs are intended to assist in the classification of those discontinuities revealed in ferrous castings subjected to magnetic particle examination.
1.3 These reference photographs are intended to be used for purposes of comparison with the magnetic particle indications observed on actual castings.

Standard Reference Photographs for
Magnetic Particle Indications on Ferrous Castings
This standard is issued under the fixed designation E 125; 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 editorial change since the last revision or reapproval.
This standard has been approved for use by agencies of the Department of Defense. These Reference Radiographs have been approved
to replace MIL-M-11473 (ORD). These Reference Photographs have been reproduced through the courtesy of the Steel Founders’
