The FIA is unlikely to sanction the dilution of the recently-decreed 2009 testing ban, set to take effect shortly before the Australian Grand Prix and run throughout the season.
The ban was introduced with the agreement of the F1 teams' FOTA alliance, but concerns about the troubled development of KERS systems has sparked suggestions that up to three official tests may be exempted this season.
It is reported that the teams will argue for the tests on the grounds that the KERS concerns could lead to mass retirements from early races this season.
But all the FOTA members would have to unanimously vote for the modification, and Max Mosley told journalists on Wednesday that the FIA would "probably not agree".
"But obviously we'll have to listen to the proposal from FOTA," he said in London.
