1.1 This test method covers the determination of density for powder metallurgy (PM) materials containing less than tWo percent porosity and for cemented carbides. This test method is based on the water displacement method.
NoreE 1- -A test specimen that gpains mass when immersed in wacer indicmes the specimen cootains surface connected porosity. Unsealed surfaoe porosity will absorb wacer and cause density values higher than the true value. This test method is nort applicable if this problem ocurs.
