A-2 Porous material density determinations
The density of a porous (oil impregnated part) can be made with the balance. Weigh the part (dry) prior to oil
impregnation and record its weight. You must also know the density value of the oil to be used in immersing the
part before starting. In this procedure, you will follow the method for solid density measurements using water.
