Williams' 2013 challenger has passed the final FIA crash test ahead of its launch in Barcelona.
The Grove-based squad used their 2012 car during the first pre-season test at Jerez last week with the main focus being on aerodynamic and tyre evaluation.
However, Pastor Maldonado and rookie Valtteri Bottas will get their first taste of the FW35 at the second test at the Circuit de Catalunya next week after the car was given the green light during the final inspection last Thursday.
The FW35 will officially be launched at 9am (GMT +1) at the Barcelona circuit next Tuesday.
