DIN 66136-1:2017-02

This document applies to the determination of the degree of dispersion, the specific metal surface area and the average crystallite size using chemisorption. The methods described in this document using platinum, palladium, nickel and copper as examples are particularly suitable for supported monometallic catalysts where the metal surface differs from the total surface, but also for other metal catalysts such as Raney catalysts. Information on the transfer to other metals can be found in Annex A. This standard has been prepared by Working Committee NA 005-11-43 AA "Partikelmesstechnik; Porositäts- und Oberflächenmessverfahren (SpA zu ISO/TC 24/SC 4/WG 3)" ("Particle characterization; Pore size distribution and porosity (Mirror Committee of ISO/TC 24/SC 4/WG 3)") at DIN Standards Committee Building and Civil Engineering (NABau).
