This part of ISO 6353 gives specifications and indicates the test methods to be used for checking conformity with these specifications for a second series of reagents used in analytical chemistry the numbering system of which continues the first series specified in ISO 6353-2.

This document should be read in conjunction with ISO 6353-1, which describes the general test methods (GM) applicable to the requirements of the reagent specifications and gives such general information as is required for the correct use of the standard.

Particular attention is drawn to ISO 6353-1, clause 4, which describes the preparation of

- standard solutions (SS) at dilutions I, II and Ill;

- reagent solutions (RS);

- indicator solutions (IS).

In this part of ISO 6353, asterisked clause reference numbers refer to the 1982 edition of ISO 6353-l.
