1. Chemical and indicator parameters
1. Chemical and indicator parameters For the parameters set out in Table 1 of this Annex, the method of analysis used shall, as a minimum, be capable of measuring concentrations equal to the parametric value with a limit of quantification, as defined in point (2) of Article 2 of Commission Directive 2009/90/EC (1), of 30 % or less of the relevant parametric value and an uncertainty of measurement as specified in Table 1 of this Annex. The result shall be expressed using at least the same number of significant figures as for the parametric value referred to in Parts B and C of Annex I to this Directive. The uncertainty of measurement laid down in Table 1 shall not be used as an additional tolerance to the parametric values set out in Annex I.
