ISO/PDTS 10303-1078 was prepared by Technical Committee ISO/TC 184, Industrial automation systems and integration, Subcommittee SC4, Industrial data.
This International Standard is organized as a series of parts, each published separately. The parts of ISO 10303 fall into one of the following series: description methods, integrated resources, application interpreted constructs, application modules, application protocols, abstract test suites, implementation methods, and conformance testing. The series are described in ISO 10303-1. A complete list of parts of ISO 10303 is available from the Internet:

Annexes A and B form an integral part of this part of ISO 10303. Annexes, C, D, E, aand F are for information only.
This application module is concerned with the standard instances of property space that are necessary for structural analysis. The nature of a property value possessed by a structure as a whole, or by a point within a structure, can be specified by reference to a standard instance of property space defined by this part of ISO 10303.
NOTE - Each standard instances of property space defined by this part of 10303 has a definition that refers to ISO 10303-104:2000.
This part of ISO 10303 is enables property values within a property space defined by ISO 10303-104:2000 to be recorded even when they are not associated with a finite element analysis.
EXAMPLE - Position is a standard instance of property space that is necessary for structural analysis.
EXAMPLE - Displacement is a standard instance of property space that is necessary for structural analysis.
EXAMPLE - Elastic strain is a standard instance of property space that is necessary for structural analysis.
EXAMPLE - Elasticity is a standard instance of property space that is necessary for structural analysis.
EXAMPLE - Stress is a standard instance of property space that is necessary for structural analysis.
This application module defines a useful set of standard instances of property space that are relevant to structural analysis.
NOTE - A property value is a class that an individual physical object can be a member of. The class indicates the nature of an observable or measurable aspect of the individual physical object.
The isotropic elasticity with a Young's modulus of 200 MPa and a Poisson's ratio of 0.3 is a property value. The points within a widget of type XYZ_123 at its operating temperature of 150 degrees Celsius are members of this property value.
A property space is a class that a property value can be a member of. The class indicates the nature of the physical phenomenon that is the criterion for the property value.
Elasticity is a property space. The isotropic elasticity with a Young's modulus of 200 MPa and a Poisson's ratio of 0.3 is a member of this property space.
The following are within the scope of this application module:
spaces of structural properties that can be possessed by a point within a solid volume of matter;
EXAMPLE - Elasticity is a property space.
EXAMPLE - Density is a property space.
spaces of structural properties that can be possessed by a fibre, that is within a solid volume of matter in the form of a shell and that extends from the top to the bottom surface of the shell;
EXAMPLE - Thickness is a property space.
EXAMPLE - 2D bending moment tensor is a property space.
EXAMPLE - Mass per unit shell area is a property space.
spaces of structural properties that can be possessed by a cross section, that is within a solid volume of matter in the form of a beam;
EXAMPLE - Cross section area is a property space.
EXAMPLE - 2D bending moment vector is a property space.
EXAMPLE - Mass per unit beam length is a property space.
spaces of structural properties that can be possessed by a solid volume of matter as a whole.
EXAMPLE - Volume is a property space.
EXAMPLE - Mass is a property space.
EXAMPLE - Total absorbed strain energy is a property space.
The following are not within the scope of this application module:
NOTE - The relationship between a property value and a property space that indicates the nature of the property value is defined in the property space application module.
NOTE - A property value is defined in the independent property definition application module. The numerical identification a property value with respect to a unit of measure is supported by the property identification application module.
