This guide describes techniques for both dry and wet magnetic particle examination, a nondestructive method for detecting cracks a9033 other discontinuities at or near the surface in ferromagnetic materials. Specify standard, Type of dye, Method, and Criteria Usage: This specification covers steel castings, surface acceptance standards, magnetic particle and liquid penetrant inspection.
E Guide for Magnetic Particle Testing. ASTM International takes no position respecting the validity of any patent rights asserted in connection with any item mentioned in this standard.
Combining values from the two systems may result in a nonconformance with this specification. Current edition approved Oct. Liquid penetrant inspection or aatm particle inspection shall be used for nondestructive inspection.

These processes are applicable for the detection asrm discontinuities, such as lack of fusion, corrosion, cracks, laps, cold shuts, and porosity, that are open or connected to the surface of the component under examination. Only indications whose major dimension exceeds 1? However, false indications may be produced by localized surface irregularities, metallurgical discontinuities, or magnetic permeability variations.

A superscript epsilon e indicates an editorial change since the last revision or reapproval. Material Testing The following standards are used to specify the various nondestructive testing methods that can be used for inspecting vehicle components.
Magnetic particle examination may be applied to raw material, billets, finished and semifinished materials, welds, and in-service parts. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date. Remember me for one month. Only direct current or rectified alternating full or half wave current shall be used as the electric power source for any of the magnetizing methods.
When agreed upon between the asttm and purchaser, the liquid penetrant method may be used to verify the presence of surface discontinuities which had been previously indicated by the magnetic particle method.
This standard does not contain acceptance standards or recommended quality levels. Individual relevant linear and nonlinear indications a93 the specified acceptance levels shall be considered unacceptable. Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend.
The following standards define specific techniques and standards used for magnetic particle type, nondestructive testing methods, that can be used for inspecting vehicle components. Individual relevant linear and nonlinear indications exceeding the specified acceptance levels shall be considered unacceptable. Within the text the SI units are shown in brackets.
They can be effectively used in the examination of nonporous, metallic materials, both ferrous and nonferrous, and of nonmetallic materials such as glazed or fully densified ceramics, certain nonporous plastics, and glass.
ASTM A903/A903M – 99(2017)
Are you sure you want to empty the cart? Users of this standard are expressly advised that determination of the validity of any such patent rights, and the risk of infringement of such rights, are entirely their own responsibility.
They are nondestructive testing methods for detecting discontinuities that are open to the surface such as cracks, seams, laps, cold shuts, laminations, through leaks, or lack of fusion and are applicable to in-process, final, and maintenance examination. This test method covers procedures for penetrant examination of materials.
Alternating current is not permitted because its capability to detect subsurface discontinuities is very limited and therefore unsuitable. Within the text the SI units are shown in brackets. Link to Active This link will always route to the current Active version of the standard. Surface conditioning may precede reexamination. All relevant indications shall be evaluated in terms of the acceptance criteria.

It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. Any indication in excess of the acceptance criteria which is believed to be false may be reexamined.
