performance characteristic

physical quantity that is related to a critical property (ISO 6707-1:2014, 9.1.3)

Note 1

In some cases, the performance characteristic can be the same as the critical property, e.g. gloss. On the other hand, if the critical property is strength, for instance, thickness (ISO 6707-1:2014, 9.2.24) or mass can be utilized as a performance characteristic, working as an indirect measure (ISO 6707-1:2014, 9.1.7) of strength.
