CS-E 150 Tests - General Conduct of Tests

(a)The fuel and oil used for all tests must normally be chosen from those specified by the Applicant, but, where it may have relevance to the results of any particular test, the actual fuel and oil to be used (including any additives) must be justified. (See AMC E 150(a))

(b)During all tests, only servicing and minor repairs must be permitted except that major repairs or replacement of parts may be resorted to, provided that the parts in question are subjected to an agreed level of penalty testing.

(c)Except where declared by the Applicant, no artificial means of increasing the humidity of the ambient air must be employed.

(d)For all tests, parameters relevant to the purpose of the test must be agreed and recorded at appropriate times during the test. Where possible, Engine conditions must be allowed to stabilise before observations are taken. In particular, observations taken less than 3 minutes after a change of Engine conditions must not be included in assessment of performance, unless the rating cannot be used for more than 3 minutes.

(e)Adjustments made in compliance with CS-E 140(c) must be checked and unintended variations from the original settings recorded after each test.

(f)All test bed equipment and all measuring equipment used for tests must be appropriately calibrated.
