Miljøstyrelsens 12. Mikrobiologiske Metodeafprøvning

1. Summary

Material and methods

In May 1998 The Danish Environmental Protection Agency accomplished the twelfth microbiological trial with participation of 32 laboratories. The aim of the trial was an evaluation of the draft standard: "Enumeration of aerobic microorganisms in hot domestic water". The material to be analysed consisted of 8 samples (1-8), which were identical in pairs, except sample 7 and 8. All samples were analysed for aerobic microorganisms according to the draft standard.
