What is BS 7591-4 - Porosity and pore size distribution of materials about?
Pore size is commonly expressed as `pore diameter'. The pore diameter is calculated from the applied gas pressure, which causes the liquid-filled pores to be emptied, resulting in a flow of gas through the sample. BS 7591-4 is an international standard that discusses the test methods for porosity and pore size distribution of materials . BS 7591-4 describes the evaluation of pore size characteristics (such as mean, maximum, and the distribution of pore sizes) that allow the flow of liquid from one side of the wetted structure to the other. It is a comparative and usually non-destructive test.
