In order to validate the conformity of water, many reference systems have been set up. In this case, the Afnor NF – T90 – 210 standard is a protocol in the field of physicochemical analysis of water and its quality control.
Thus, the NF-T90-210 puts forward the various analyses to be carried out, the thresholds to be respected, etc… and makes it possible to evaluate in particular the exactitude and the fidelity of the results.
