BS 7310:1990

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.

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