Originally approved in Combining values from the two systems may result in a nonconformance with this specification.

They can be effectively used axtm 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.

Land Use and Development. The values stated in each system are not exact equivalents; therefore each system must be used independently of the other. Liquid penetrant inspection or magnetic particle inspection shall be used for nondestructive inspection. Personnel performing examination shall be qualified in accordance with an acceptable written procedure as agreed upon between the purchaser and manufacturer.

The penetrant examination processes described in this practice are applicable to in-process, final, sstm maintenance in-service inspections. Please login to your authorized staff account to use this feature.

Wstm attempt has been made to establish limits of acceptability or the metallurgical cause of a discontinuity. These processes are applicable for the detection of 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.

Search book title Enter keywords for book title search. This standard does not contain acceptance standards or recommended quality levels. This specification covers acceptance criteria for the surface inspection of steel castings when nondestructively examined by magnetic particle or liquid penetrant inspection. Alternating current is not permitted because its capability to detect subsurface discontinuities is very limited and therefore unsuitable.

The values stated in each system are not exact equivalents; therefore each system must be used independently of the other. This standard defines the terminology used in the standards prepared by the E07 Committee on Nondestructive Testing.

A number in parentheses indicates the year of last reapproval. Abstract This specification covers steel castings, surface acceptance standards, magnetic particle and liquid penetrant inspection.

Only indications whose major dimension exceeds 1? All relevant indications shall be evaluated in terms of the acceptance criteria. The following standards define specific 9a03 and standards used for acceptance of nondestructive testing.

Material Testing

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. However, false indications may be produced by localized surface irregularities, metallurgical discontinuities, or magnetic permeability variations. Today, some 12, ASTM standards are used around the world to improve product quality, enhance safety, facilitate market access and trade, and build consumer confidence.

The following standards define specific techniques and standards used for magnetic particle type, nondestructive testing methods, that can be used for inspecting vehicle components. This guide describes techniques for both dry and wet magnetic particle examination, a nondestructive method for detecting cracks and other discontinuities at or near the surface in ferromagnetic materials.

This specification covers steel castings, surface acceptance standards, magnetic particle and liquid penetrant inspection.

Guide E can be used in conjunction with this practice as a tutorial. Copyright Compu-tecture, Inc. 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.

Non Destructive Testing The following standards define specific techniques and standards used for acceptance of a03 testing.
