ISO 4829-2 : 1988 (El Foreword ISO (the International Organization for Standardization) is a worldwide federation of national Standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Esch member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, govern- mental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization Draft International Standards adopted by the technical committees are circulated to the member bodies for approval before their acceptance as International Standards by the ISO Council. They are approved in accordance with ISO procedures requiring at least 75 % approval by the member bodies voting. International Standard ISO 4829-2 was prepared by Technical Committee ISO/TC 17, S teeL Users should note that all International Standards undergo revision from time to time and that any reference made herein to any other International Standard implies its latest edition, unless otherwise stated.

Reagents supplied in glass bottles, once opened, may absorb moisture and become reactive to glassware. Alkaline reagents, e.g. sodium carbonate and sodium Peroxide, are particularly susceptible. To avoid the risk of significant contamination arising from this Source, it is recommended that only freshly opened bottles of all reagents be used for the preparation of reagent solutions. In addition, only water prepared by distillation shall be used for the preparation of reagent solutions and throughout the pro- cedure. Water demineralized by ion-exchange shall not be used as it may contain significant amounts of colloidal silica. To avoid adventitious contamination, the water shall be prepared, as required, for the specific purpose, and collected in po
