CHEMICAL PARAMETERS
Part I: Directive requirements - prescribed concentration or values
1 The parametric value refers to the residual monomer concentration in the water as calculated according to specifications of the maximum release from the corresponding polymer in contact with the water. This is controlled by product specification. | ||
2 See also the nitrate-nitrite formula in regulation 4(c). | ||
3 For these purposes, “pesticides” means—
| ||
4 “Pesticides total” means the sum of the concentrations of the individual pesticides detected and quantified in the monitoring process. | ||
5 The specified compounds are—
| ||
6 The parametric value applies to the sum of the concentrations of the individual compounds detected and quantified in the monitoring process. | ||
7 The specified compounds are—
