9、 Method using flow injection analysis (FIA) (D 2)”: Method DIN EN ISO 14403-1 D 2 During work on the revision ISO 14403:2002-03 has been divided into two parts. DIN EN ISO 14403-1 covers the new method using flow injection analysis (FIA), the text has been adjusted accordingly and the title has been

10、 changed. The method using continuous flow analysis (CFA) as specified in ISO 14403:2002 is now dealt with in DIN EN ISO 14403-2. The DIN Standards corresponding to the International Standards referred to in this document are as follows: ISO 3696 DIN ISO 3696 ISO 5667-3 DIN EN ISO 5667-3 ISO 5725-2

11、DIN ISO 5725-2 ISO 8466-1 DIN 38402-51 ISO 8466-2 DIN ISO 8466-2 Expert assistance and specialized laboratories will be required to perform the analysis described in this standard. Existing safety regulations are to be taken into account. Depending on the objective of the analysis, a check shall be

12、made on a case-by-case basis as to whether and to what extent additional conditions will have to be specified.
