1. The concentration limits fixed in the following tables, expressed as a weight/weight percentage, determine the classification of the preparation in relation to the individual concentration of the substances present whose classification is also shown.
Classification of the substance | Classification of the preparation | ||
---|---|---|---|
N, R50-53 N, R51-53 R52-53 | N,R50-53 see Table 1b | N, R51-53 See Table 1b Cn ≥25% | R52-53 see Table 1b 2.5%≤ Cn <25% Cn≥25% |
For preparations containing a substance classified with N, R50-53, the concentration limits and the resulting classification given in Table 1b are applicable.
LG50 or EC50 value (“L(E)C50”) of substance classified as N, R50-53 (mg/l) | Classification of the preparation | ||
---|---|---|---|
N, R50-53 N, | R51-53 | R52-53 | |
0.1 <L(E)C50 ≤1 | Cn ≥ 25% | 2.5% ≤ Cn <25% | 0.25% ≤ Cn <2.5% |
0.01 <L(E)C50 ≤0.1 | Cn ≥ 2.5% | 0.25% ≤ Cn <2.5% | 0.025% ≤ C*subn; <0.25% |
0.001 <L(E)C50 ≤0.01 | Cn ≥ 0.25% | 0.025% ≤ Cn <0.25% | 0.0025% ≤ Cn <0.025% |
0.0001 <L(E)C50 ≤0.001 | Cn ≥ 0.025% | 0.0025% ≤ Cn <0.025% | 0.00025% ≤ Cn <0.0025% |
0.00001 <L(E)C50 ≤0.0001 | Cn ≥ 0.0025% | 0.00025% ≤ Cn <0.0025% | 0.000025% ≤ Cn <0.00025% |
For preparations containing substances with a lower LC50 or EC50 value than 0.00001 mg/l, the corresponding concentration limits are calculated accordingly (in factor 10 intervals).
LC50 or EC50 value (“L(E)C50”) of substance classified either as N, R50 or as N, R50-53 (mg/l) | Classification of the preparation N, R50 |
---|---|
0.1 L(E)C50 ≤1 | Cn≥ 25% |
0.01 L(E)C50 ≤0.1 | Cn≥ 2.5% |
0.001 L(E)C50 ≤0.01 | Cn≥ 0.25% |
0.0001 L(E)C50 ≤0.001 | Cn≥ 0.025% |
0.00001 L(E)C50 ≤0.0001 | Cn≥ 0.0025% |
For preparations containing substances with a lower LC50 or EC50 value than 0.00001 mg/l, the corresponding concentration limits are calculated accordingly (in factor 10 intervals).
Classification of the substance | Classification of the preparation R52 |
---|---|
R52 | Cn ≥25% |
Classification of the substance | Classification of the preparation R53 |
---|---|
R53 | Cn ≥25% |
N, R50-53 | Cn ≥25% |
N, R51-53 | Cn ≥25% |
R52-53 | Cn ≥25% |

Impact Assessments generally accompany all UK Government interventions of a regulatory nature that affect the private sector, civil society organisations and public services. They apply regardless of whether the regulation originates from a domestic or international source and can accompany primary (Acts etc) and secondary legislation (SIs). An Impact Assessment allows those with an interest in the policy area to understand:
