Reference photographs are supplied as a means of establishing types and characteristics of surface discontinuities detectable by the penetrant inspection methods.

Additionally ferrous metals that have low magnetic permeability, or high alloy steels such as austenitic stainless steels, may be more effectively tested using dye penetrant methods.

Material Testing The following standards are used to specify the various nondestructive testing methods that can be used for inspecting vehicle components. Enter your account email address to request a password reset: Search book title Enter keywords for book title search.

No attempt has xstm made to establish limits of acceptability or the metallurgical cause of a discontinuity. Liquid penetrant examination is suitable for determining surface discontinuities on both ferrous and non-ferrous metals, and other materials.


The penetrant examination processes described in this practice are applicable to in-process, final, and maintenance in-service inspections. 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.

The following standards define specific techniques and standards used for magnetic particle type, nondestructive asgm methods, that can be used for inspecting vehicle components. Historical Version s – view previous versions of standard.

Magnetic particle examination is not applicable to nonferromagnetic metals and alloys. This test method covers a procedure for the magnetic particle examination of steel forgings using alternating current as the power source. Only alternating cycle current shall be used as the electric power source for any of the magnetizing methods.

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. Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters. Alternating current is not permitted because its capability to detect subsurface discontinuities is very limited and therefore unsuitable.

Magnetic particle examination may be applied s903 raw material, billets, finished and semifinished materials, welds, and in-service parts. There were no books found for the applied search filters. Combining values from the two systems may result in a nonconformance with this speci?

ASTM A903/A903M – 99(2017)

This standard is subject to revision at any time by the responsible technical committee and must be reviewed every? Your a930 will receive careful consideration at a meeting of the responsible technical committee, which you may attend. The ability to detect subsurface discontinuities is very limited when using a9903 alternating power source, and therefore the test surfaces should be in the final thermally treated and finish machined condition.

Abstract This specification covers steel castings, surface acceptance standards, magnetic particle and liquid penetrant inspection. This abstract is a brief summary of the referenced standard. The values stated in each system are not exact equivalents; therefore each system must be used independently of the other.

Individual relevant linear and nonlinear indications exceeding the specified acceptance levels shall be considered unacceptable. Liquid penetrant inspection or magnetic particle inspection shall be used for nondestructive inspection.
