3.—(1) Solid and liquid preparations: For substances that produce severe effects after repeated or prolonged exposure (R48), the individual concentration limits specified in Table III determine, when appropriate, the classification of solid and liquid preparations and shall determine the particular risk phrases which shall be assigned to them.
| Classification of the substance | Classification of the preparation | |
|---|---|---|
| T | Xn | |
(*) In accordance with the approved classification and labelling guide and depending on the classification, the risk phrases R20 to R28 are also to be assigned to indicate route of administration or means of exposure. | ||
| T with R48 | conc. ≥ 10% R48(*) obligatory | 1% ≤ conc. < 10% R48(*) obligatory |
| Xn with R48 | conc. ≥ 10% R48(*) obligatory | |
(2) Gaseous preparations: For gases that produce severe effects after repeated or prolonged exposure (R48), the individual concentration limits specified in Table IIIA determine, when appropriate, the classification of gaseous preparations and shall determine the particular risk phrases which shall be assigned to them.
| Classification of the substance (gas) | Classification of the gaseous preparation | |
|---|---|---|
| T | Xn | |
(*) In accordance with the approved classification and labelling guide and depending on the classification, the risk phrases R20, R23 or R26 are also to be assigned to indicate route of administration or means of exposure. | ||
| T with R48 | conc. ≥ 5% R48(*) obligatory | 0.5% ≤ conc. < 5% R48(*) obligatory |
| Xn with R48 | conc. ≥ 5% R48(*) obligatory | |
