Requirements for performance and other essential characteristics including measuring apparatus. Recommended procedures for determining ions given in Appendix.

This British Standard specifies performance requirements and other requirements for ion-selective electrodes, reference electrodes and combination (dual) ion-selective electrodes in general laboratory use, and for ion-selective electrode meters for laboratory use.

NOTE 1 An outline of procedures used for determining ionic species (except hydrogen ion), and neutral species indirectly, using ion-selective electrodes, is given in Appendix A.

NOTE 2 Recommended tests of performance of electrodes are described in Appendix B.

NOTE 3 Instrument check tests are described in Appendix C.

NOTE 4 Appendix D covers standard reference solutions for direct potentiometry.

NOTE 5 The titles of the publications referred to in this standard are listed on the inside back cover. The numbers in square brackets represent the bibliographical references given in Appendix E.
