There sure is. According to EASA Certification Specification Engine CSE 510 under “Safety Analysis” one of the failure definitions regarded as Hazardous Engine Effects is the non-containment of high energy debris.

And in CSE 520 “Strength”

(c) (1) The strength of the Engine must be such that the shedding of compressor or turbine blades, either singly or in likely combinations, will not result in a Hazardous Engine Effect

(d) Design consideration must be given to avoiding the risk of major rupture of Engine casings (particularly those which are subjected to high pressure loads) in the event of a local Failure in the casing or damage to the casing arising, for example, from a torching flame following a combustion system Failure.

So in a nutshell Rolls Royce, this is a big FAIL.
