## CS-E 330 Tests - General

A single Engine must be used for all the tests except that, if so desired, the vibration, calibration, and detonation tests may be made on Engines of the same type as the Engine used for the other tests so long as there is essential similarity to that Engine. The vibration tests may be made during preliminary development of the type provided that the design standard and power rating of the Engine used do not differ essentially from the prototype.
