1.2 The concentration limits expressed as a volume/volume percentage in Table IA determine the classification of the gaseous preparations in relation to the individual concentrations of the gas(es) present whose classification is also shown.
| Classification of the substance (gas) | Classification of the preparation | ||
|---|---|---|---|
| T+ | T | Xn | |
The R phrases denoting risk shall be assigned to the preparation in accordance with the following criteria— (i) the label shall include one or more of the above mentioned R phrases according to the classification used, (ii) in general, the R phrases selected should be those applicable to the substance(s) present in the concentration which gives rise to the most severe classification. | |||
| T+ with R26, R27, R28 | concentration ≥ 1% | 0.2% ≤ concentration <1% | 0.02% ≤ concentration < 0.2% |
| T with R23, R24, R25 | concentration ≥ 5% | 0.5% ≤ concentration < 5% | |
| Xn with R20, R21, R22 | concentration ≥ 5% | ||
