ASTM does not give any warranty express atm implied or make any representation that the contents of this abstract are accurate, complete or up aztm date. This standard defines the terminology used in the standards prepared by the E07 Committee on Nondestructive Testing.

Personnel performing examination shall be qualified in accordance with an acceptable written procedure as agreed upon between the purchaser and manufacturer. Abstract This specification covers steel castings, surface acceptance standards, magnetic particle and liquid penetrant inspection. Specify standard, Type of dye, Method, and Sensitivity Usage: Combining values from the two systems may result in a nonconformance with this astj.

Within the text the SI units are shown in brackets. Remember me for one month. The following standards define specific techniques and standards used for magnetic particle type, nondestructive testing methods, that can be used for inspecting vehicle components.

All relevant indications shall be evaluated in terms of the acceptance criteria.

Atm 1 2 3 4 5 page sstarting from page current page. 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 liquid penetrant type, nondestructive testing methods that satm be used for inspecting vehicle components. The values stated in each system are not exact equivalents; therefore each system must be used independently of the other. Only indications whose major dimension exceeds 1?

Combining values from the two systems may result in a nonconformance with this speci? Individual reprints single or multiple copies of this standard may be obtained by contacting Axtm at the above address or at phonefaxor service astm.

Liquid penetrant inspection or magnetic particle inspection shall be used for nondestructive inspection. When agreed upon between the manufacturer 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.

Alternating current is not permitted because its capability to detect subsurface discontinuities is very limited and therefore unsuitable. Non Destructive Testing The following standards define specific techniques and standards used for acceptance of nondestructive testing. A number in parentheses indicates the year of last reapproval. 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.

Combining values from the two systems may result in a nonconformance with this specification. This specification covers steel castings, surface acceptance standards, magnetic particle and liquid penetrant inspection.

Are you sure you want to empty the cart? The values stated in each system are not exact equivalents; therefore each system must be used independently of the other. Magnetic particle examination may be applied to raw material, billets, finished and semifinished materials, welds, and in-service parts. Individual relevant linear and nonlinear indications exceeding the specified acceptance levels shall be considered unacceptable. Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters.

Copyright Compu-tecture, Inc. Actual dimensions including maximum length of indications and number of indications per unit area must be specified by the users of this document. If you like to setup a quick demo, let us know at support madcad. This practice establishes minimum requirements for magnetic particle examination used for the detection of surface or slightly subsurface discontinuities in ferromagnetic material. Land Use and Development. Reference photographs are supplied as a means of establishing types and characteristics of surface discontinuities detectable by the penetrant inspection methods.

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.
