Bibliography

Intends to: - give terminology, definitions and requirements for statements by manufacturers for analyzers, sensor units, and electronic units used for the determination of the electrolytic conductivity of aqueous solutions; - confirm performance tests for such analyzers, sensor units and electronic units; - specify basic documents to support the applications of quality assurance standards.

IEC 60746-3:2002 is intended to specify terminology, definitions and requirements for statements by manufacturers for analyzers, sensor units, and electronic units used for the determination of the electrolytic conductivity of aqueous solutions; to establish performance tests for such analyzers, sensor units and electronic units; to provide basic documents to support the applications of quality assurance standards.

This publication is to be read in conjunction with IEC 60746-1:2003.
