Was the A330 actually certified for the flight plan it filed?

It seems based on the first BEA report that at FL350 the temperatures were EXPECTED to be lower than. -40C and there is nothing unusual about that I assume, yet according to Appendix 4 of the second (interim) report this was the very limit of the Certification of the Pitot tubes.

So, if the pitot tubes are not certified below -40C, then how can the A330 be, or are we just relying on "Ice will not be a problem below -40C" ?

After all the previous examples of Incorrect Airspeed, below -40C, why did we have to wait for this loss before recommending that the certification needed adjusting to encompass what is after-all a fairly routine temperature range?
