ICS Number Code Historical Version s – view previous versions of standard. Guide E may be utilized for magnetic particle examination in the field for machinery components originally manufactured from steel forgings. This standard does not contain acceptance standards or recommended quality levels. The values stated in each system may not be exact equivalents; hterefore, each system shall be used independently of the other.

Alternating current is not permitted because its capability to detect subsurface discontinuities is very limited and therefore unsuitable. This abstract is a brief summary of the referenced standard. The procedure will produce consistent results upon which acceptance standards can be based.

It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

If the requirements of this test method are in conflict with the requirements of Practice Ethe requirements of this test method shall prevail. Indications to be evaluated are grouped into three broad classes, namely: Forgings may be magnetized in the longitudinal or circular direction by employing the surge or continuous current flow methods.

The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. The procedure will produce consistent results upon which acceptance standards can be based. This standard does not contain acceptance standards or recommended quality levels.

The inspection medium shall consist of finely divided ferromagnetic particles, whose size, shape and magnetic properties, both individually and collectively, shall be taken satm account.

However, unless the order specifies the applicable “M” specification designation [SI units], the material shall be furnished to inch-pound units. Combining values from the two systems may result in nonconformance with the specification. The parts shall also be sufficiently demagnetized after inspection so that residual or leakage fields will not interfere with future operations to which the steel forgings shall be used for.
