This standard specifies requirements on carrying out interlaboratory trials for external quality control of laboratories. With respect to the purpose the standard differs from DIN 38402-41 and DIN 38402-42, which are used for quantitative statements about reliability of analytical methods. In this standard requirements are specified for the organizer of interlaboratory trials as well as on planning, carrying out and evaluation of interlaboratory trials for external quality control of laboratories.

The standard describes a chemical method for an exclusiontest for strong chelating agents in waste water. The basis for the method is the weakening of the colour intensity of a red coloured complex in a solution by the strong chelating agents. Result of the analysis is a yes or no-statement about the existence of these agents.
