Spain and Great Britain are set to each hold two-day Formula 1 in-season tests in 2016,Autosport has learned.
Barcelona’s Circuit de Catalunya and British Grand Prix venue Silverstone will be the hosts.
The Tuesday and Wednesday tests will take place following the Spanish GP, on May 17-18, and the British GP, on July 12-13.
The 2016 F1 sporting regulations allow for two team tests of no more than two consecutive days duration.
They must take place at circuits where a grand prix has just been held and begin no less than 36 hours later.
The regulations add that each team must allocate at least two of the four days for young driver testing.
Barcelona and the Red Bull Ring hosted in-season tests last year, and Silverstone was last used for F1 testing in 2014.
The running will be in addition to the two pre-season tests, which take place in Barcelona between February 22-25 and March 1-4.
There will also be a number of days dedicated to tyre testing to allow Pirelli to test rubber for the planned 2017 rule revamp, though these dates are to be confirmed.
