ASTM International takes no position respecting the validity of any patent rights asserted in connection with any item mentioned in this standard. Within the text the SI units are shown in brackets.

This abstract is a brief summary of the referenced standard. Specify standard, Type aztm dye, Method, and Sensitivity Usage: 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.

The following standards define specific techniques and standards used for acceptance of nondestructive testing. Liquid penetrant examination is suitable for determining surface discontinuities on both ferrous and non-ferrous metals, and other materials.

Actual dimensions including maximum length of indications and number of indications per unit area must be specified by the users of this document. 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.

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. This test method covers procedures for penetrant examination of materials. This practice establishes minimum requirements for magnetic particle examination used for the detection of surface or slightly subsurface discontinuities in ferromagnetic material.

The values stated in each system are not exact equivalents; therefore each system must be used independently of the other. Search book title Enter keywords for book title search. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

Alternating current is not permitted because its capability to detect subsurface discontinuities is very limited and therefore unsuitable. Remember me for one month.

Non Destructive Testing The following standards define specific techniques and standards used for acceptance of nondestructive testing. This standard does not contain acceptance standards or recommended quality levels.

Your comments will receive careful consideration at a meeting of the responsible technical committee, asmt you may atsm. Within the text the SI units are shown in brackets. This standard is subject to revision at any time by the responsible technical committee and must be reviewed every? These nondestructive testing NDT methods include: Land Use and Development.

Material Testing

Liquid penetrant inspection or magnetic particle inspection shall be used for nondestructive inspection. The following standards define specific techniques and standards used for magnetic particle type, nondestructive testing methods, that can be used for inspecting vehicle components.

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. 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.

This test method covers a procedure for the magnetic particle examination of steel forgings using alternating current as the power source. 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. 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.

Combining values from the two systems may result in a nonconformance with this specification. Specify standard, Type of dye, Method, and Criteria Usage: If you feel that your comments have not received a fair hearing you should make your views known to the ASTM Committee on Standards, at the address shown below.

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.

Only alternating cycle current shall be used as the electric power source for any of the magnetizing methods. A number in parentheses indicates the year of last reapproval.

This test method provides a procedure for magnetic particle examination of steel forgings. Combining values from the two systems may result in a nonconformance with aztm specification. E Guide for Magnetic Particle Testing.
