Scope

This CEN report gives the results of inter-laboratory testing to compare the accuracy and convenience of the official EC method for porosity measurement (given as Annex B) with two non-standardized alternative methods (given as 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.
