RELIABILITY SCORING CRITERIA
50.1 basis. This scoring criteria is based on the reliability
scoring procedure approved by the Department of the Army. w It was
extracted from the "XM204 Howitzer Scoring Criteria Plan dated
May 1973. The Failure Scoring Procedure (see 50.2) provides for
the use of the Failure definition (see 60.1.3) which is amplified
(see 50.1.1). Failure modes (see 50.1.2], Degraded modes of
Operation (see 50.1.3) and Failure exclusions (see 50.1.1.1)
pertaining to the cannon provide additional failure scoring
guidelines as specified in the "XM204 Howitzer Scoring Criteria
Plan" dated May 1973.
50.1.1
Failure definition amplification.
50.1.1.1 The following are not considered as reliability
failures:
a.
Scheduled replacement of parts before failure.
b.
An incipient malfunction corrected during scheduled
preventive maintenance on the part in question provided a
