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

Please login to your authorized staff account to use this feature. These nondestructive testing NDT methods include: This test method covers procedures for penetrant examination of materials. ASTM International takes no position respecting the validity of any patent rights asserted in connection with any item mentioned in this standard.

This practice establishes minimum requirements for magnetic particle examination used for ast detection of surface or slightly subsurface discontinuities in ferromagnetic material.

ASTM A903/A903M – 99(2017)

Individual relevant linear and nonlinear indications exceeding the specified acceptance levels shall be considered unacceptable. This practice establishes the minimum requirements for conducting liquid penetrant examination of nonporous metal, and nonmetal components. Individual relevant linear and nonlinear aa903 exceeding the specified acceptance levels shall be considered unacceptable. No items in cart.

A superscript epsilon e indicates an editorial change since the last revision or reapproval. Evaluation of Indications 6. Specify standard name, desired criteria if any Usage: Personnel performing examination shall be qualified in accordance with an acceptable written procedure as agreed upon between the purchaser and manufacturer.

Liquid penetrant inspection or magnetic particle inspection shall be used for nondestructive inspection. The ability to detect subsurface discontinuities is very limited when using an alternating power source, and therefore the test surfaces should be in the final thermally treated and finish machined condition.


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. All adtm indications shall be evaluated in terms of the acceptance criteria. Search book title Enter keywords for book title search.

When agreed upon between the manufacturer and purchaser, the liquid penetrant method may be used sstm verify the presence x903 surface discontinuities which had been previously indicated by the magnetic particle method.

The values stated in each system are not exact equivalents; therefore each system must be used independently of the other. This abstract is a brief summary of the referenced standard. Liquid penetrant examination is suitable for determining surface discontinuities on both ferrous and non-ferrous metals, and other materials.

Alternating current is not permitted because its capability to detect subsurface discontinuities is very limited and therefore unsuitable. 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.

The following standards define specific techniques and standards used for acceptance aastm nondestructive testing. 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.

This specification covers steel castings, surface acceptance standards, magnetic particle and liquid a9003 inspection. Abstract This specification covers steel castings, surface acceptance standards, magnetic particle and liquid penetrant inspection. These processes are applicable for the detection of discontinuities, such as lack of fusion, corrosion, cracks, laps, cold shuts, and porosity, asfm are open or connected to the surface of the component under examination.


Magnetic particle examination may be applied to raw material, semifinished material billets, blooms, castings, and forgingsfinished material and welds, regardless of heat treatment or lack thereof.

This test method provides a procedure for magnetic particle examination of steel forgings. Are you sure you want to empty the cart? Land Use and Development.
