ADR special packing provision BB2
RID/ADR only: UN 1203 may use IBCs only if its actual vapour pressure stays within 110 kPa (50 °C) or 130 kPa (55 °C).
UN 1203 may be carried in IBCs under IBC02 only when its actual vapour pressure is no higher than 110 kPa measured at 50 °C, or no higher than 130 kPa measured at 55 °C. This applies even though special provision 534 in 3.3.1 would otherwise govern the vapour pressure of the product. The provision is specific to RID and ADR.
| Value | Applies when |
|---|---|
| 110 kPa | maximum actual vapour pressure at 50 °C |
| 130 kPa | maximum actual vapour pressure at 55 °C |
Note. Appears only in IBC02.
Refers to: 3.3.1; special provision 534.
