Definition: ability of a product or material to function as required, under specified conditions of use, maintenance, repair and update until a limiting state prevents its functioning

Notes on definition:

• Note 1 to entry: Durability can be expressed in units appropriate to the part or product concerned (e.g., operating cycles, distance run). The units should always be clearly stated.
• Note 2 to entry: Durability is influenced by reliability, maintenance, repair, and updates (e.g., in software).

CLEPA comments:

• Comment 1: Ecodesign for Sustainable Products Regulation (ESPR)6 defines durability as the “ability of a product to maintain over time its function and performance under specified conditions of use, maintenance and repair”. The ISO definition is the same with additional notes.
