ABSTRACT

This standard specifies the Brunauer, Emmett, multi-molecular layer Teler (BETNSA) adsorption theory multi-point method to determine the total surface Product, as well as the external surface area measured by statistical thickness surface area of \u200b\u200bthe adsorption method. This standard applies to carbon black for rubber, dye black, acetylene black and precipitated hydrated silicon dioxide (silica).
