ASTM B311 Standard Test Procedure for Density Testing of Low-Porosity Powder Injection Molding Materials

/ / Published in CIE test methods, Science and Research

ASTM B311 is an important standard for determining the density of low-porosity powder metallurgy (PM) materials. This test is based on the principle of water displacement and is particularly valuable for quality control of high-density PM materials and cemented carbides. The method is especially suitable for materials with less than two percent porosity, making it ideal for precision applications in air…
