Mercedes, Force India and Toro Rosso have become the latest teams to try out the Halo safety device.
Nico Rosberg, Nico Hulkenberg and Carlos Sainz ran the unit in Friday practice at Spa with Mercedes driver setting the fastest time of Practice One for this weekend's Belgian GP with the device attached to his W07 car.
Although the sport has scrapped plans to introduce the cockpit protection component for next season, the FIA, the sport's governing body, still want the Halo to be brought in for 2018.
Rosberg said: "The team have done a great job on the Halo. It doesn't disturb me when driving. I could go fast straight away and even set the best time of the session with it this morning, so I think that was a success."
Red Bull's Daniel Ricciardo also ran the Halo on Friday at Spa. The former world champions had previously trialled the unit during a test session at Silverstone in July.
"From a visibility point of view, it wasn't too bad," reported Red Bull boss Christian Horner. "There were some restrictions around the side but it is a work in progress."
