LIFE-CYCLE COST ANALYSIS .
2-11.1
Include a life-cycle cost analysis in the comparison of design alternative s.
The expected equipment operating life must be based on an engineering assessment of
the realistic operational life. Do not use equipment warranty periods as the expected
service life unless the manufacturer provides convincing evidence that the equipment is
capable of this operational life.
