3 Terms and definitions

3.1 Terms defined in ISO 10303-1

For the purposes of this document, the following terms defined in ISO 10303-1 apply:

3.2 Other terms and definitions

For the purposes of this document, the following definitions apply:

3.2.1
physical quantity space; property space; property type

set of values or magnitudes for a physical phenomenon

NOTE    A physical quantity space is a class that a physical quantity value can be a member of. Whether or not a physical quantity value is a member of the class is determined by the nature of the physical phenomenon that is observed or measured.

3.2.2
physical quantity value; property value; independent property definition

magnitude of an aspect of a physical thing that can be observed or measured, or deduced from observations or measurements

NOTE    A physical quantity value is a class that a physical thing is can be a member of. Whether or not a physical thing is a member of the class is determined by the observation or measurement.

3.2.3
property; characteristic

function from a set of physical objects to a physical quantity space

NOTE    A property distribution is a mapping from a particular set of physical objects, which can be distributed with respect to space, time or both.
