Gaseous preparationsI11.2

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.

Table IA

Classification of the substance

Classification of the preparation

T+

T

Xn

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%

The R phrases denoting risk shall be assigned to the preparation in accordance with the following criteria—

  1. i

    the label shall include one or more of the above mentioned R phrases according to the classification used,

  2. 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.
