TS EN IEC 60300-3-10

TS EN IEC 60300-3-10 is an application guide within dependability management that addresses the basic principles of maintainability and maintenance activities. Applied to equipment, software, services and structures, it explains what maintainability means in practice, how maintenance should be planned across the life cycle, and how technical and financial decision-makers can assess these topics together.

How maintainability and maintenance fit together

Maintainability is the degree to which an item can be maintained or restored efficiently, while maintenance is the set of actions taken to keep it in, or return it to, a required state. In general technical terms, these are closely linked to reliability, availability and supportability. Design choices such as accessibility and ease of disassembly matter on one side, while planned and corrective maintenance, spare parts, tools, training and information management matter on the other.

What this guide focuses on

• The value and nature of maintainability and maintenance characteristics
• Interfaces with reliability, availability and supportability, including life-cycle trade-offs
• The elements of maintainability and maintenance programmes
• Application of these programmes throughout the life cycle
• Techniques for ensuring requirements are met
• Management of maintainability and maintenance data and information

This second edition is a technical revision that replaces the first edition published in 2001. It adds more guidance on establishing a maintenance programme and removes some guidance on support and supportability, which has been moved to IEC 60300-3-14. The result is a guide that treats maintenance not as an isolated operational task, but as a life-cycle discipline shaped by design, procurement, operation and long-term support decisions.
