Application module: Property identification | ISO/TS 10303-1085:2005(E) © ISO |
TECHNICAL SPECIFICATION | ISO/TS 10303-1085:2005(E) |
This part of ISO 10303 specifies the application module Property identification. The following are within the scope of this part of ISO 10303:
the unit of measure used to identify a physical quantity instance;
EXAMPLE 1 The unit of measure Kelvin is a mapping from the space of temperatures to the space of real numbers.
the coordinate system used to identify a physical quantity instance;
the encoding rule used to identify a physical quantity instance;
EXAMPLE 2 A strain can be represented by an array of 6 numbers using the mathematical or the engineering convention.
EXAMPLE 3 A direction can be represented by a normalised array of 3 numbers which are its direction cosines, or by two Euler angles.
the specification of the identification method for compound property spaces such as (pressure, temperature, density) or (position, temperature), with respect to the identification methods for the individual component physical quantity spaces.
The following are outside the scope of this part of ISO 10303:
a physical quantity instance;
NOTE 1 A physical quantity instance is within the scope of the Independent_property_definition application module.
a physical quantity space;
NOTE 2 A physical quantity space is within the scope of the Property_space application module.
a maths value;
NOTE 3 A maths value is within the scope of the Maths_value application module.
a maths space.
NOTE 4 A maths space is within the scope of the Maths_space application module.
