CS-E 600 Tests - General

(a)All tests must be made with air intakes conforming to an acceptable design that is as representative of the powerplant intakes as is practicable.

(b)All tests must be made with acceptable representative jet pipes and propelling nozzles, except as permitted under CS-E 740(f)(4)(i). The approval of other jet pipes and / or propelling nozzles for particular installations will be considered individually as necessary.

(c)Unless otherwise required for specific tests, any optional air bleed must be closed during all relevant tests.

(d)In cases where dirt accumulates within the Engine due to the test house environment, it will be acceptable to clean the Engine internally at agreed intervals during the endurance test of CS-E 740 by an agreed method which does not involve stripping any part of the Engine or necessitate the removal of the Engine from the test bed.

(e)Engines for Rotorcraft. All tests must normally be made with the Engine mounted in the attitude in which it will be installed. (See AMC E 600(e)).
