New ASTM E1444 2011 Edition on Standard Practice for Magnetic Particle Testing

ASTM E1444, “Standard Practice for Magnetic Particle Testing,” has been issued as a new 2011 Edition with a redesignation to ASTM E1444/E1444M-11.  This new document number shows that the document has been revamped to include both feet and inches and metric measurements.  It replaces MIL-STD-1949, as well as the previous ASTM E1444-05 Edition from 2005.

This practice establishes minimum requirements for magnetic particle testing used for the detection of surface or slightly subsurface discontinuities in ferromagnetic material. Guide ASTM E709 can be used in conjunction with this practice as a tutorial.

Magnetic particle testing consists of magnetizing the area to be examined, applying suitably prepared magnetic particles while the area is magnetized, and subsequently interpreting and evaluating any resulting particle accumulations. Maximum detectability occurs when the discontinuity is positioned on the surface and perpendicular to the magnetic flux.

The magnetic particle testing method is used to detect cracks, laps, seams, inclusions, and other discontinuities on or near the surface of ferromagnetic materials. Magnetic particle testing may be applied to raw material, billets, finished and semi-finished materials, welds, and in-service parts. Magnetic particle testing is not applicable to non-ferromagnetic metals and alloys such as austenitic stainless steels.

ASTM E1444/E1444M establishes the basic parameters for controlling the application of the magnetic particle testing method. This practice is written so that it can be specified on the engineering drawing, specification, or contract. It is not a detailed how-to procedure to be used by the examination personnel and, therefore, must be supplemented by a detailed written procedure that conforms to the requirements of this practice.

New ASTM E1417 2011 Edition on Standard Practice for Liquid Penetrant Testing

There’s a new edition of the popular Standard Practice for Liquid Penetrant Testing, ASTM E1417-11 2011 Edition.  The 11 page revision replaces the ASTM E1417-05(e1) Edition from 2005 and the MIL-STD-6866.  The document establishes the minimum requirements for conducting liquid penetrant examination of nonporous metal, and nonmetal components.

The document has been redesignated to ASTM E1417/E1417M.  This redesignation means that the document contains measurements in both metric and feet and inches.

This practice is written so it can be specified on the engineering drawing, specification, or contract. It is not a detailed how-to procedure to be used by the inspector and, therefore, must be supplemented by a detailed procedure that conforms to the requirements of this practice. Specification ASTM E165 contains information to help develop detailed requirements.

The penetrant examination processes described in this practice are applicable to in-process, final, and maintenance (in-service) examinations. 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.

Caution must be exercised in the usage of elevated temperature with components manufactured from thermoplastic materials. Also, some cleaners, penetrants, and developers can have a deleterious effect on nonmetallic materials such as plastics. Prior to examination, tests should be conducted to ensure that none of the cleaning or examination materials are harmful to the components to be examined.
