Guide with the aim of providing detailed and comprehensive guidance on a coordinated programme of within-laboratory and between-laboratory quality control to ensure the achievement of results of adequate and specified accuracy in the analysis of waters and associated materials. The Technical Report applies to the chemical and physiochemical analysis of natural waters (including sea water), waste water, raw water meant for producing potable water. It is not meant for application to the analysis of sludges and sediments and does not address the biological or microbiological examination of water.
