From kilograms to obligation
What a given charge means for the CO₂ equivalent and for the check interval.
| Charge | CO₂ equivalent | Leak check |
|---|---|---|
| 2 kg | 0.012 t | This is not a fluorinated greenhouse gas. The F-gas Regulation imposes no leak check here; other rules on safety and pressure equipment may still apply. |
| 5 kg | 0.03 t | This is not a fluorinated greenhouse gas. The F-gas Regulation imposes no leak check here; other rules on safety and pressure equipment may still apply. |
| 10 kg | 0.06 t | This is not a fluorinated greenhouse gas. The F-gas Regulation imposes no leak check here; other rules on safety and pressure equipment may still apply. |
| 25 kg | 0.15 t | This is not a fluorinated greenhouse gas. The F-gas Regulation imposes no leak check here; other rules on safety and pressure equipment may still apply. |

In CertiFlow
When you book a charge with this refrigerant, the CO₂ equivalent is calculated using the GWP above and fixed at that moment. A later change to the table does not alter your history.
