The proposed tests should be conducted with the. diesel in i
- its actual operational configuration, in so far. as practi-cable.
Exceptions to this -procedure (such as cranks installed to turn the:-unit over and venting prior to start) should be reviewed to determine the extent to which they affect the val _idity of the tests.
