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

Material Testing

Guide E can be used in conjunction with this practice as a tutorial. However, false indications may be produced by localized surface irregularities, metallurgical discontinuities, or magnetic permeability variations. Any indication in excess of the acceptance criteria which is believed to be false may be reexamined. Specify standard, Type of dye, Method, and Sensitivity Usage: The penetrant examination processes described in this practice are applicable to in-process, final, and maintenance in-service inspections.

The magnetic particle examination method is used to detect cracks, laps, seams, inclusions, and other discontinuities on or near the surface of ferromagnetic materials.

This specification covers steel castings, surface acceptance standards, magnetic particle and liquid penetrant inspection. This practice asm minimum requirements for magnetic particle examination used for the detection of surface or slightly subsurface discontinuities in ferromagnetic material. It is useful for preventive maintenance examination. Surface conditioning may precede reexamination. Current edition approved Oct. The following standards define specific techniques and standards used for acceptance of nondestructive testing.


Specify standard, Type of dye, Method, and Asttm Usage: Specify standard name, desired criteria if any Usage: A number in parentheses indicates the year of last reapproval. Only indications whose aatm dimension exceeds 1? This practice establishes the minimum requirements for conducting liquid penetrant examination of nonporous metal, and nonmetal components.

Magnetic particle examination may be applied to raw material, billets, finished and semifinished materials, welds, and in-service parts. Today, some 12, ASTM standards are used around the world to improve product quality, enhance safety, facilitate aa903 access and trade, and build consumer confidence. No attempt has been zstm to establish limits of acceptability or the metallurgical cause of a discontinuity. 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.

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. Within the text the SI units are shown in brackets. E Guide for Magnetic Particle Testing. Combining values from the two systems may result in a nonconformance with this speci? They are nondestructive testing methods for detecting discontinuities that are open to the z903 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 standard defines the terminology used in the standards prepared by the E07 Committee on Nondestructive Testing. This specification covers acceptance criteria for the surface inspection of steel castings wstm nondestructively examined by magnetic particle or liquid penetrant inspection.



This test method covers a procedure for the magnetic particle examination of steel forgings using alternating current as the power source. Liquid penetrant examination is suitable for determining surface discontinuities on both ferrous and non-ferrous metals, and other materials. The values stated in each system are not exact equivalents; therefore each system must be used independently of the other. Magnetic particle examination is not applicable to nonferromagnetic metals and alloys.

Personnel performing q903 shall be qualified in accordance with an acceptable written procedure as agreed upon between the purchaser and manufacturer. This abstract is a brief summary of the referenced standard. Only alternating cycle current shall be used as the electric power source for any of the magnetizing methods.

ASTM A903/A903M – 99(2017)

The following standards define specific techniques and standards used for magnetic particle type, nondestructive testing methods, that can be used for inspecting vehicle components. Are you sure you want to empty the cart?
