ISO/PDTS 10303-1082 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 inter-preted 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.
The properties possessed by a product change during its life. This application module is concerned with the condition of a product at an instant.
The concept of state is valid for an individual product.
EXAMPLE - The product that is 'widget serial number 98/1234' was in the state 'widget serial number 98/1234 as delivered' until 1999-03-15.
On 1999-03-15, widget serial number 98/1234 was started up for the first time.
EXAMPLE - The product that is 'widget serial number 98/1234' was in the state 'widget serial number 98/1234 at maximum power on 1999-05-07' from 10:30 to 15:47 on 1999-05-07.
The concept of state is valid for a product specification or class of product.
EXAMPLE - Each individual product to the product specification 'widget type XYZ' is delivered in an individual state to the state specification 'widget type XYZ as delivered'.
An individual widget of type XYZ is no longer in a state to this specification once it has been started up for the first time.
EXAMPLE - Each individual product to the product specification 'widget type XYZ' can be in an individual state that is to the state specification 'widget type XYZ running at maximum power'.
An individual widget of type XYZ can be in an individual states to this specification on many different occasions.
This application module supports the definition of a state and its relationship to a product or class of product.
The following are within the scope of this application module:
the dependence of one state upon the simultaneous existence of another.
EXAMPLE - The existence of an individual state of specification 'widget type XYZ running at maximum power' depends upon the existence of an individual state of specificiation 'widget type rotor turning at 3000 rpm'.
EXAMPLE - The existence of an individual state of specification 'widget type XYZ vibrating' depends upon the existence of an individual state of specification 'widget type rotor turning with a speed between 2500 and 2600 rpm'.
The following are not within the scope of this application module:
NOTE - A property of a state is defined in the possession of property module. A property distribution over a space of states is defined in the property distribution module.
