MEL — Master Equipment List

The authoritative register of equipment assets within a facility or organization.

Definition

A Master Equipment List (MEL) is the authoritative register of equipment assets maintained throughout the asset lifecycle. It provides a unique record for each equipment item, including identification, classification, location and other key attributes used to support engineering, operations, maintenance and asset management activities.

Why It Matters

The Master Equipment List provides the definitive inventory of equipment assets used across engineering, operations and maintenance systems.

In Practice

The Master Equipment List commonly serves as the primary source for equipment master data within enterprise asset management and computerized maintenance management systems and is synchronized with related engineering and business systems where appropriate.

Common Misuse

A Master Equipment List records the organization's equipment assets, whereas Master Data Management governs the quality and consistency of the data maintained within that register and other enterprise systems.
