New Porous Certified Reference Materials (CRMs); Method: Mercury Intrusion - Pressure range between 0.2 and 2 MPa; BAM-124 - BAM-P126

  • The main problem in the certification of pressure-volume curves for the high-pressure range of the mercury intrusion is the fact that the uncertainty of the pressure (x-axis) should not be neglected. Additionally, the use of pressure-volume curves from different laboratories using different apparatus leads to incomparability of these curves and requires a correction. This is known in the statistical literature as warping. The use of point wise intervals causes difficulties in the interpretation of the results. Such problems have been eliminated in the certification of pressure-volume curves of the new standards ERM®-FD123 and BAM-P124 to BAM-P126. These standards are reference materials for the comparatively low-pressure range of the mercury intrusion method. The materials BAM-P124 and BAM-P126 are made up as flat membranes. The production of these membranes (a-alumina ceramics) was carried out in the HITK, Hermsdorf, Germany.

The production of these membranes (a-alumina ceramics) was carried out in the HITK, Hermsdorf, Germany. The long ceramic tape was divided into 50 rectangular tapes. These tapes were sintered. Each of the tapes has been cut in 30 dies, numbered by a laser beam. Samples were assigned systematically covering all 50 tapes to allow for an optimal modelling of material inhomogeneities.zeige mehrzeige weniger
