Scope

This document gives the results of inter-laboratory testing to compare the accuracy and convenience of the official EC method for porosity measurement (given in Annex B) with two non-standardized alternative methods (given in Annexes C and D) already used in some participating laboratories.
Three products, with a porosity between 1 % and 7 %, have been used in the inter-laboratory trials.
