PART 5Methods of analysis relating to chemical parameters
SECTION 1Methods of analysis
Minimum performance characteristics18
1
For the purpose of paragraph 17(a), a method of analysis for a parameter specified in the first column of the table in Section 2 (minimum performance characteristics for a method of analysis) is a method of analysis that complies with minimum performance characteristics if it is a method of analysis that—
a
is capable of measuring concentrations equal to the parametric concentration of that parameter with a limit of quantification of 30% or less of the relevant parametric concentration,
b
has an uncertainty of measurement that does not exceed the percentage of the parametric concentration for the parameter specified in the second column of the table,
c
in the case of benzo(a)pyrene, complies, where relevant, with the requirement specified in the third column of the table, and
d
in the case of cyanide, complies with the requirement specified in the fourth column of the table.
2
In the case of a parameter specified in the first column of the table in Section 2, where a method of analysis that complies with the requirements of sub-paragraph (1) is used to determine whether the concentration of that parameter exceeds the concentration specified for that parameter in the table in Part 3 of Schedule 2, the result of the analysis carried out using that method of analysis must be expressed using at least the same number of significant figures as the number of significant figures used to specify that parametric concentration in the table in Part 3 of Schedule 2.
