Measurement of pore size distribution in bricks or granular raw materials.

This Section of BS 1902-3 describes a method for the measurement of pore size distributions of solid and granular refractory material. The method can be used to measure pore diameters in the approximate range 0.006 µm to 600 µm.

NOTE 1 The assumed model in this method has all the pores parallel sided and of circular cross section; the results are reported as equivalent pore diameters. A model for pores of different cross section, e.g. elliptical, can be derived by making appropriate adjustments to the mathematics.

NOTE 2 This method is unsuitable for materials that:

  1. contain volatile compounds which give off vapours when placed under vacuum;
  2. contain metals that amalgamate with mercury.

NOTE 3 The titles of the publications referred to in this standard are listed on the inside back cover.
