INTRODUCTION
Reliability – centred maintenance (RCM) is based on the following precepts:
- A failure is an unsatisfactory condition. There are two types of failures: Functional failures, usually reported by operating engineering staff, and potential failures, usually discovered by maintenance engineering staff.
- The consequences of a functional failure determined the priority of maintenance effort.
A reliability – centred maintenance programme includes only those tasks which satisfy the criteria for both applicability and effectiveness. The applicability of a task is determined by the characteristics of the item, and its effectiveness is defined in terms of the consequences the task is designed to prevent.
