TS EN 60300-3-11

TS EN 60300-3-11 is an application guide within dependability management for applying reliability centred maintenance (RCM). It addresses how to develop failure management policies for equipment and structures using RCM analysis techniques, providing a structured way to base maintenance decisions on function, failure modes and operational consequences rather than on routine or generic intervals alone.

In general technical terms, RCM is a maintenance philosophy that examines what an asset is supposed to do, how that function can fail, and what the impact of failure would be on operations. The objective is to choose the most suitable preventive, condition-based, inspection, or corrective actions for each failure scenario instead of applying the same maintenance treatment to every item. This makes RCM widely relevant where reliability, availability, safety and maintenance resources must be balanced.

How this guide frames RCM analysis

• The standard gives guidance for developing maintenance policies through RCM analysis.
• Its scope includes both equipment and structures.
• It notes that maintenance activities related to preventive maintenance, as recommended in the related standards, may be implemented using this guide.
• The edition is described as applying across all industries and as defining a revised RCM algorithm and analysis approach.
• It serves as an application guide linked to IEC 60300-3-10, IEC 60300-3-12 and IEC 60300-3-14.

For organisations that need a disciplined maintenance decision process, this document provides a common RCM framework that can be adapted to different industrial contexts. Its value lies in helping users distinguish critical functions from less consequential ones, so maintenance effort can be directed where it is most effective. Rather than prescribing a narrow, asset-specific routine, it supports a methodical reliability-based approach suitable for broader use.
