The specification of compositional relationships between materials. The specification of a material as a component of a typical material or another material.

end_time (O, K, I: ndt_date_tod)

End time of the association. Inherited from transient_association.


start_time (O, K, I: ndt_date_tod)

Start time of the association. Inherited from transient_association.


characterize (M, K: material) (0881)

This describes the material whose composition is being described. Each component_material must characterize one material.


incorporate (M, K: material(component_of_material))

This describes another material that is a component of the material whose composition is being described. Each component_material must incorporate one material.


description (O, I: ndt_comment)

A description of the transient association. Inherited from transient_association.


duration (O, I: ndt_time)

Defines the duration of the association expressed in any valid units of time. Inherited from transient_association.


caused_by (O, I: activity(cause_association))

Specifies the activity which establishes this association. Each component_material may be caused by one activity. Inherited from transient_association.


data_collection (I, V: SET[0:?] data_collection(collection_content))

Indicates the data collections that include this instance of E and P data. Each component_material may be a member of one or more data_collection. Inherited from e_and_p_data.


graphical_element (I, V: SET[0:?] graphical_element(depicted_object))

Specifies one or more graphical elements which are depicting this data item. Each component_material may be depicted by one or more graphical_element. Inherited from e_and_p_data.


pty_mass_fraction (V: SET[0:?] pty_mass_fraction(component_material))

Each component_material may have a property of one or more pty_mass_fraction.


pty_mole_fraction (V: SET[0:?] pty_mole_fraction(component_material))

Each component_material may have a property of one or more pty_mole_fraction.


pty_volume_fraction (V: SET[0:?] pty_volume_fraction(component_material))

Each component_material may have a property of one or more pty_volume_fraction.


ref_transient_period (O, I: ref_transient_period) (1222)

The type of period over which the property applies, such as day, month, quarter, cumulative, etc. Inherited from transient_association.


terminated_by (O, I: activity(terminate_association))

Specifies the activity which established the termination of a transient association between two objects. Each component_material may be terminated by one activity. Inherited from transient_association.


uncertainty_class (O: uncertainty_class(component_material))

Indicates the degree of confidence or certainty associated with this composition. Each component_material may be classified by one uncertainty_class.

Local rules:

Uniqueness Constraint (0881)
end_time, start_time, characterize, incorporate
[I: transient_association] Instance Value Constraint (1259)
If REF_TRANSIENT_PERIOD is EVENT, then both START_TIME and END_TIME must either be blank or be identical.
[I: transient_association] Instance Value Constraint
If REF_TRANSIENT_PERIOD is either YEAR TO DATE, MONTH TO DATE or CUMULATIVE, then END_TIME must be instantiated.
[I: transient_association] Instance Value Constraint
If REF_TRANSIENT_PERIOD is ANNUAL, SEMIANNUAL, QUARTER, MONTHLY, DAILY, or HOURLY, then either both START_TIME and END_TIME are blank or both must be instantiated.
Supertype path(s):
e_and_p_data > association > transient_association > material_composition > component_material.
