Petrol vapour recovery during refuelling of motor vehicles

Petrol vapour recovery during refuelling of motor vehicles at service stations - Part 2: Test methods for verification of vapour recovery systems at service stations

For our customers we carry out authorised (eligible) measuring efficiency of petrol vapour recovery during refuelling of motor vehicles at service stations based on European Standard STN EN 16321-2. 

We are using three measurement principles:

1) Measurement principle with simulated petrol flow (dry test method)

2) Measurement principle with real petrol flow (wet test method A)
