Classification of the substance
Classification of the preparation
N, R50-53
N, R51-53
R52-53
For preparations containing a substance classified with N, R50-53, the concentration limits and the resulting classification given in table 1b are applicable.

see Table 1b
see Table 1b
N, R51-53
Cn ≥ 25%
2.5% ≤ Cn < 25%
