ISO 11894-1:2013

ISO 11894-1:2013 describes a test method for the determination of ionic conductivity of oxide-ion-conducting solid electrolytes by the 4-terminal method with alternating current (AC 4-terminal method). ISO 11894-1:2013 applies to solid electrolytes which have oxide ionic transference numbers higher than 0,99. The applicable conductivity range shall be 1 to 1,000 S m−1. Values expressed in this International Standard are in accordance with the International System of Units (SI).
