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.

2. Notes to Table 1

2.   Notes to Table 1

Note 1

:

Uncertainty of measurement is a non-negative parameter characterising the dispersion of the quantity values being attributed to a measurand, based on the information used. The performance criterion for measurement uncertainty (k = 2) is the percentage of the parametric value stated in the table or any stricter value. The uncertainty of measurement shall be estimated at the level of the parametric value, unless otherwise specified.

Note 2

:

If the value of uncertainty of measurement cannot be met, the best available technique should be selected (up to 60 %).

Note 3

:

The method determines total cyanide in all forms.

Note 4

:

The value for the uncertainty of measurement is expressed in pH units.

Note 5

:

Reference method: EN ISO 8467.

Note 6

:

The performance characteristics for individual pesticides are given as an indication. Values for the uncertainty of measurement as low as 30 % can be achieved for several pesticides, while higher values up to 80 % may be allowed for a number of pesticides.

Note 7

:

The performance characteristics apply to individual substances, specified at 25 % of the parametric value in Part B of Annex I.

Note 8

:

The performance characteristics apply to individual substances, specified at 50 % of the parametric value in Part B of Annex I.

Note 9

:

The uncertainty of measurement should be estimated at the level of 3 mg/l of the total organic carbon (TOC). EN 1484 Guidelines for the determination of TOC and dissolved organic carbon (DOC) shall be used for the specification of the uncertainty of the test method.

Note 10

:

The uncertainty of measurement should be estimated at the level of 1,0 NTU (nephelometric turbidity units), in accordance with EN ISO 7027 or another equivalent standard method.
