The FIA will send its own observers to the Formula 1 young driver test later this month to ensure that current racers do not work on car developments.
Motor racing's governing body has agreed to a change of the testing regulations that will allow teams to use their regular drivers to help out with tyre work at the Silverstone test from July 17-19.
The move comes on the back of the multiple Pirelli tyre failures at the British Grand Prix, and should help Pirelli find a solution that will eradicate the problems it has suffered so far this year.
But with the FIA making it clear that the experienced drivers are only allowed to work on the emergency tyre programme, it plans to send its own officials to the test.
These observers will check the running programmes of every team to ensure any car development work is only done by the 'young' drivers who will still be present at the test.
Pirelli has still yet to announce the result of its investigation of what went wrong at Silverstone to cause the series of failures.
The company is expected to announce later on Tuesday that it will bring the Kevlar-belted tyres that were trialled at the Canadian Grand Prix to Germany this weekend.
A bigger change of specification will then come in time for the Hungarian GP, with teams able to test these tyres at Silverstone.
Pirelli also has two further private tests planned in the next few weeks, with the FIA having told its motorsport director Paul Hembery at Silverstone that it would be willing to allow the tyre company to use a 2013 car if it is required.
