Application module: Independent property definition | ISO/TS 10303-1099:2005(E) © ISO |
TECHNICAL SPECIFICATION | ISO/TS 10303-1099:2005(E) |
This part of ISO 10303 specifies the application module Independent property definition. The following are within the scope of this part of ISO 10303:
an observable or measurable quantity;
NOTE 1 This concept is called a 'physical quantity instance'.
EXAMPLE 1 The temperature of 400 degrees Celsius is a physical quantity instance.
NOTE 2 A physical quantity instance is a class that has members. The members of 400 degrees Celsius are all objects that have this temperature.
the physical quantity space that contains a physical quantity instance;
NOTE 3 A physical quantity space contains different physical quantity instances for the same physical phenomenon.
EXAMPLE 2 Temperature is a physical quantity space. The physical quantity instance that is the temperature of 400 degrees Celsius is a member of this space.
the symmetry of a physical quantity instance;
EXAMPLE 3 Isotropic is a symmetry of a physical quantity instance. The physical quantity instance that is the elasticity with Young's modulus of 210000 MNm-2 and Poisson's ratio of 0.3 has isotropic symmetry.
The following are outside the scope of this part of ISO 10303:
a property distribution over a set of parts or features within a product, or a set of states within an activity;
a relationship between an physical quantity instance and an individual product or activity, or a class of product or activity;
NOTE 4 These relationships are within the scope of the Possession_of_property and Property_condition application modules.
a numerical description of physical quantity instance with respect to a scale.
NOTE 5 The description of the physical quantity instance 400 degrees Celsius by the number 400 with respect to the Celsius scale, is within the scope of the Property_identification application module.
