Abstract:	This article discusses recent developments in materials and test method standards in the field of powder metallurgy. The Metal Powder Industries Federation (MPIF) and the Metal Powder Producers Association (MPPA) are responsible for maintaining and developing these standards. The article highlights changes made to material standards, such as the addition of data for different alloys and the inclusion of new sinter hardened materials. It also discusses the Test Methods Assurance Program (TMAP), which allows participating companies to compare the accuracy of their test results with others in the industry. Additionally, the article mentions updates made to specific test method standards, such as tensile properties and particle size analysis. The given text provides information on recent developments in materials and test method standards by the Metal Powder Industries Federation (MPIF). The text includes data tables and descriptions of various standards, such as MPIF Standard 43 for apparent hardness of powder metallurgy (PM) products, MPIF Standard 46 for tap density of metal powders, MPIF Standard 58 for surface roughness of PM products, and MPIF Standard 75 for flow rate of metal powders using the Carney flowmeter funnel. The text also mentions the need for interlaboratory studies to determine the precision of these test methods. The text discusses various developments in materials and test method standards in the field of powder metallurgy. It mentions the availability of a certified calibration powder for Carney flow rate testing and the development of a new standard for determining ejection stresses for un [Extracted from the article]
