This International Standard specifies a method for the determination of the following six water-soluble organic complexing agents in the concentration range from 0,5 micrograms/litre to 200 micrograms/litre:

• EDTA (ethylenedinitrilotetraacetic acid);
• NTA (nitrilotriacetic acid);
• DTPA (diethylenetrinitrilopentaacetic acid);
• MGDA (methylglycinediacetic acid);
• ?-ADA (?-alaninediacetic acid);
• 1,3-PDTA (1,3-propylenedinitrilotetraacetic acid).

The method is applicable to drinking, ground, surface and waste water.
