TS EN 62550

TS EN 62550 is the standard addressing spare parts provisioning for products, equipment and systems so that continuity of operation can be sustained in their intended application. Its focus is the planning and management of spare parts as part of supportability activities that influence dependability performance.

The technical role of spare parts provisioning

Spare parts provisioning is a core logistics and maintenance-planning discipline that helps restore assets after failure, keep maintenance timely, and preserve service continuity over the useful life of equipment. It is not just about holding inventory; it also involves part identification, compatibility, interchangeability, availability, lead time, and deciding what level of provision is appropriate for the expected operating context. This standard sets out requirements for that subject.

What this standard covers

• It addresses requirements for spare parts provisioning as part of supportability activities.
• It is aimed at sustaining continuity of operation for products, equipment and systems in their intended application.
• It focuses on spare-parts management issues that affect dependability performance.
• It provides a technical framework for why parts planning matters in maintenance and operations continuity.

In general technical terms, spare-parts strategies often include safety stock for critical components, consideration of long procurement times, management of obsolescence and alignment between maintenance tasks and logistics. A well-defined spare-parts approach helps reduce the impact of unexpected interruptions and supports equipment availability. This standard provides the requirements framework for that purpose.

The document is presented as the European adoption linked to EN 62550:2017 and IEC 62550.
