Advancing PM



The Metal Powder Industries Federation issues standards to provide the design and materials engineer with the information necessary for specifying PM materials which have been developed by the PM and MIM parts, powder, and equipment producers. MPIF standards are intended to present and clarify PM technology so as to aid in the conduct of business. PM materials specifications and test standards relate to those activities that concern designers and users of PM parts as well as the manufacturer.

The use of any MPIF standard is entirely voluntary. Existence of an MPIF standard does not in any respect preclude any member of MPIF or non-members from manufacturing or selling products not included in the standards. Suppliers are at liberty to supply products or to use procedures other than those identified in any standard.

The standards fall into three basic classifications:

  1. Materials Specifications for components

  2. Methods of test (for powders and components)

  3. Powder Metallurgy Press Safety standards (developed in cooperation with the American National Standards Institute)

Material Specifications

The material specifications are divided into four categories and standards have been developed for each category. Both the purchaser and the manufacturer should, in order to avoid possible misconceptions or misunderstandings, agree on the following conditions prior to the manufacture of a PM part: minimum strength value, grade selection, chemistry, proof testing, typical property values and processes, which may affect the part application. These standards are cross referenced with ASTM and ISO standards. Click here to view the Newsletter on ISO Standards in Powder Metallurgy

Methods of Test

The Standard Test Methods for Metal Powders and Powder Metallurgy Products has been developed to provide guidance for PM technology users and suppliers. They have been adopted in cooperation with member trade associations through committees comprised of technical experts responsible for developing standards within their areas of expertise and proposing them to the MPIF membership. Before a standard can be issued as an official MPIF standard, it must be approved by the MPIF membership as a whole. The standards have all been adopted under this procedure.

This new 2012 edition contains 42 standards covering terminology and recommended methods of test for metal powders, powder metal and metal injection molded parts, metallic filters, and powder metallurgy equipment. The new edition contains 3 new standards (Std. 67—Guide to Sample Preparation for the Chemical Analysis of the Metallic Elements in PM Materials, Std. 68Guide to Temperature Profiling a Continuous Mesh-Belt Sintering Furnace and Std. 69Guide for the Determination of the Porosity in Powder Metallurgy Products Using Automated Image Analysis), revisions—some major in scope—to 26 other standards and new or updated Precision Statements for 7 standards.

Powder Press Safety Standards

This American National Standard for Machine Tools—Metal Powder Compacting Presses: Safety Requirements for Construction Care and Use was prepared in conjunction with MPIF and the B11.16 subcommittee of ANSI. The standard was developed to eliminate injuries to personnel associated with presses used in powder metallurgy, by establishing safety requirements for the construction, safeguarding, care and use of PM presses.
