IEC 60746-2:2003 specifies terminology, definitions and requirements for statements by manufacturers for analyzers, sensor units and electronic units used for the determination of the pH of aqueous solutions; to establish performance tests for such analyzers, sensor units and electronic units. It provides basic documents to support the applications of quality assurance standards ISO 9001, ISO 9002 and ISO 9003.
This publication is to be read in conjunction with IEC 60746-1:2003.
