ISO/PDTS 10303-1074 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 possession of a property by a product, state or activity.
A property can be associated with the following:
This means that an observable or measurable aspect of the whole life of a product has the property.
EXAMPLE - The product that is 'widget serial number 98/1234' lasted for 10000 load cycles. The number of cycles before breaking for the product life is a measurable aspect that has the value '10000 load cycles to break'.
A properties that does not change during the life of a product can be treated in the same way.
EXAMPLE - The product that is 'widget serial number 98/1234' has 5 bolt holes. The number of bolt holes is a measurable aspect that has the value '5 bolt holes'.
Strictly speaking this property value is a variation of number of bolt holes with state during the lifetime of the product that is constant.
This means that an observable or measurable aspect of a product in a state has the property.
EXAMPLE - The product that is 'widget serial number 98/1234' has a mass of 10 Kg in its as delivered state. The mass is a measurable aspect of the state 'widget serial number 98/1234 as delivered'.
EXAMPLE - The product that is 'widget serial number 98/1234' has a temperature that varies from point to point within the body of the product at maximum power on 1999-05-07. The temperature distribution is a measurable aspect of the state 'widget serial number 98/1234 at maximum power on 1999-05-07'.
This means that an observable or measurable aspect of a whole activity performed by a product has the property.
EXAMPLE - The product that is 'widget serial number 98/1234' pumps 1000 tonnes of water during its pumping activity on 1999-05-07. The mass of water pumped is a measurable aspect of the activity 'widget serial number 98/1234 pumping during 1999-05-07'.
EXAMPLE - The product that is 'widget serial number 98/1234' has a temperature that varies from point to point within the body of the product and from time to time during its pumping activity on 1999-05-07. The time varying temperature distribution is a measurable aspect of the activity 'widget serial number 98/1234 pumping during 1999-05-07'.
This application module supports the relationship between a product, state or activity and a property.
The following are within the scope of this application module:
the possession of a property by the whole life of an individual product;
EXAMPLE - The individual product that is 'widget serial number 98/1234' lasted for 10000 load cycles. The property value '10000 load cycles to break' is possessed by the product.
EXAMPLE - The individual product that is 'widget serial number 98/1234' has 5 bolt holes. The property value '5 bolt holes' is possessed by the product throughout its life.
This property value is a variation of number of bolt holes with state during the lifetime of the product that is constant.
the possession of a property by a state in the life of an individual product;
EXAMPLE - The individual product that is 'widget serial number 98/1234' has a mass of 10 Kg in its as delivered state. The property value '10 Kg' is possessed by the state 'widget serial number 98/1234 as delivered'.
EXAMPLE - The individual product that is 'widget serial number 98/1234' has a temperature that varies from point to point within the body of the product in its running state on 1999-05-07. The temperature distribution is possessed by the state 'widget serial number 98/1234 running on 1999-05-07'.
the possession of a property by an activity in the life of an individual product;
EXAMPLE - The individual product that is 'widget serial number 98/1234' pumps 1000 tonnes of water during its pumping activity on 1999-05-07. The property value '1000 tonnes of water pumped' is possessed by the activity 'widget serial number 98/1234 pumping during 1999-05-07'.
EXAMPLE - The individual product that is 'widget serial number 98/1234' has a temperature that varies from point to point within the body of the product and from time to time during its pumping activity on 1999-05-07. The time varying temperature distribution is possessed by the activity 'widget serial number 98/1234 running on 1999-05-07'.
the possession of a property by the whole life of each member of a class of product;
EXAMPLE - Each member of the product design that is 'widget type XYZ' is predicted to last for 10000 load cycles. The property value '10000 load cycles to break' is possessed by the product design.
EXAMPLE - Each member of the product design that is 'widget type XYZ' is deemed to have 5 bolt holes. The property value '5 bolt holes' is possessed by the product design.
the possession of a property by each member of a class of state;
EXAMPLE - Each member of the product design that is 'widget type XYZ' is predicted to have a mass of 10 Kg in its as delivered state. The property value '10 Kg' is possessed by the class of state 'widget type XYZ as delivered'.
EXAMPLE - Each member of the product design that is 'widget type XYZ' is predicted to have a particular variation of temperature from point to point within its body when in its running state. This temperature distribution is possessed by the class of state 'widget type XYZ running'.
the possession of a property by each member of a class of activity;
EXAMPLE - Each member of the product design that is 'widget type XYZ' is predicted to have a start up activity that lasts for 12 seconds. The property value 12 seconds is possessed by the class of activity that is 'widget type XYZ start up'.
EXAMPLE - Each member of the product design that is 'widget type XYZ' is predicted to have a particular variation of temperature from point to point within its body and from state to state within its start up activity. This temperature distribution with respect to state and position within the body is possessed by the class of activity that is 'widget type XYZ start up'.
the possession of a behaviour by the whole life of each member of a class of product;
EXAMPLE - The individual product 'spring with serial number S_1234' is predicted to have the specified load/extension behaviour. Each state of this spring is predicted to have a load property and an extension property that lies on the curve.
the possession of a behaviour by the whole life of each member of a class of product.
EXAMPLE - Each member of the product design that is 'spring type XYZ' is predicted to have the specified load/extension behaviour. Each state of each member of the class is predicted to have a load property and an extension property that lies on the curve.
