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.

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.
The current edition contains 45 standards covering terminology and recommended methods of test for metal powders, powder metal and metal injection molded parts, metallic filters, and powder metallurgy equipment.
General Information VI provides details (QR codes and Internet links) on viewing educational video clip demonstrations of the working mechanics of a number of cited test methods.
Powder Press Safety Standards
The 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.
Note: 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.
