New standards released for metal powder testing, bearings

New 2010 editions of two powder metallurgy (PM) standards have been issued by the Metal Powder Industries Federation (MPIF).

The 130-page Standard Test Methods for Metal Powders and Powder Metallurgy Products contains 39 individual standards on terminology and recommended methods for testing metal powders, PM parts, metal injection molded (MIM) parts, metallic filters, and PM equipment. In addition to a new standard on sample preparation for the determination of the total carbon content of PM materials (excluding cemented carbides), the new edition features revisions on 10 standards.

The 28-page Standard 35, Materials Standards for PM Self-Lubricating Bearings, has a new material section on diffusion-alloyed iron-bronze bearings; new information on oil impregnation efficiency; revised information for bronze bearings; and data table modifications.

Both editions cross-reference comparable ASTM and ISO standards.

The standards are available for a fee in soft-cover, electronic, and CD-ROM formats.
