TS IEC 60300-3-11

TS IEC 60300-3-11 is an application guide within dependability management for reliability centred maintenance (RCM). It provides guidance on how to use RCM techniques when developing an initial preventive maintenance program for equipment and structures. In general technical terms, RCM is a maintenance approach that bases maintenance decisions on what functions the asset must perform, how it can fail, and what the consequences of those failures may be, rather than relying only on fixed-interval servicing.

What reliability centred maintenance means

RCM is a systems-based maintenance philosophy aimed at directing maintenance effort to the functions and failure modes that matter most. In practice, it helps identify which functions need to be preserved, which failure modes are credible, what the effects of those failures are, and which maintenance tasks are actually worthwhile. This makes RCM especially relevant for complex equipment, infrastructure assets, and structural elements where a one-size-fits-all maintenance schedule is often inefficient or ineffective.

Where this standard is focused

• Developing preventive maintenance programs for equipment and structures
• Structuring maintenance tasks around functions, failure modes, and consequences
• Using RCM techniques as guidance for an initial program development effort
• Systematising maintenance decisions within dependability management

This document is an application guide for maintenance concept and decision-making, not a claim that it prescribes one mandatory maintenance recipe for every asset type. Its value is in helping users build a more reasoned, defensible, and functionally targeted maintenance program using RCM principles as the organising framework.
