Definitions related to material efficiency

Scope

Standardisation Request M/543 requires the following: "Definition of parameters and methods relevant for assessing durability, upgradability and ability to repair, re-use and re-manufacture of products". Hence, this Technical Report "Definitions related to material efficiency" will constitute a collection of common terms used in deliverables prepared in accordance with M/543. The purpose of such a collection is to provide a single definition of key terms used in different deliverables from the CEN-CENELEC TC10.
The source of the terms and definitions can be documents developed in the various working groups of the CEN-CENELEC TC10 or any text referenced by such documents.
In case of discrepancies between multiple definitions for the same term, this Technical report will recommend a preferred definition.
