适用范围：This European Standard describes two methods for determination of the bulk density and open porosity of ceramic matrix composites with fibrous reinforcement. Two methods are described and are designated as Methods A and B, as follows : — method A : determination of bulk density only by measurement of dimensions and mass ; — method B : determination of bulk density and open porosity by liquid displacement. NOTE Method B is not suitable for the determination of the open porosity for materials which are known to have an average pore size of greater than 200 μm.
