periodical inspection - Opis:
- The paper deals with the problem of choosing an appropriate inspection interval for monitoring of safety related control systems in machinery. According to international standards the safety related systems are categorized according to their Safety Integrity Levels or Performance Levels, depending on their reliability parameters. Extremely simple, approximate models have been proposed in order to provide practitioners without reliability training with useful tools for the determination of inspection policies. The method(s) based on the required availability of the system. The paper presents some practical examples of systems of categories B, 1 and 3, respectively. The frequencies of periodical inspection are calculated for: system monitoring closure of the door, behind which a dangerous element moves slowly, system of monitoring the access door on the automated production line and system, in which a light curtain is employed to monitor the access to the dangerous zone of an automatic assembly machine.
