Dangerous Goods Labelling/SF6 Filling Quantity
Overview of dangerous goods labelling
According to ADR (= European agreement concerning the international transport of dangerous goods by road), the forwarder is subject to all labelling obligations.
Transport of 600 l pressure gas vessels
When filling 600 l pressure vessels with SF6 or SF6 gas mixtures, please note that the filling quantity depends on the composition of the gas mixture:
Filling quantity depending on the SF6 percentage and test pressure (ph) of the pressure vessel
|SF6 percentage; residual air||Filling degree at 70 bar test pressure [kg/l]||Filling degree at 100 bar test pressure [kg/l]|
|≥ 99,9 %||1,06||1,23|
|≥ 99,0 %||1,02||1,20|
|≥ 95,0 %||0,83||1,09|
|≥ 90,0 %||0,62||0,94|
|≥ 80,0 %||0,37||0,66|
You have a gas mixture with a percentage of 96.2 SF6 and want to fill it into a 600 l pressure vessel with a test pressure of 70 bar.
Maximum filling degree: 0.83 kg/l
Maximum filling quantity = filling degree x Pressure vessel volume
= 0.83 kg/l x 600 l = 498 kg.
It is allowed to fill the pressure vessel with 498 kg SF6/air mixture.
The values of the table are guide values. To determine the exact filling degree, please contact us, stating the percentage actually measured.
