| Name | Data Type | Unit / Valid values | Required | Definition |
|---|---|---|---|---|
| body material | Text |
— | Optional | Is a possessed aspect being a role of the substance of an artefact when used to construct the artefact from. Therefore the substance should be in a solid state at the conditions at which the artefact exists. |
| cold differential test pressure | Number |
bar gauge | Optional | Is the pressure at which the pressure relief valve is adjusted to open on the bench. It includes corrections for back pressure and/or temperature |
| constant back pressure | Number |
bar gauge | Optional | A back pressure that does not change under any conditions of operation. |
| design specification | Text |
— | Optional | A specification according to which an item is intended to be designed |
| fluid name | Text |
— | Optional | The name of the product in liquid or gas phase. |
| fluid phase | Text |
— | Optional | Specify if the fluid is in liquid, gas or both phases. |
| lower limit design temperature | Number |
degree celsius | Optional | The lowest temperature at which a functional or physical object is designed. |
| nominal inlet diameter | Number |
millimetre | Optional | Is a diameter by which a quantitative diameter is referred to. Typically a standardized value with defined tolerances. |
| nominal outlet diameter | Number |
millimetre | Optional | Is a diameter by which a quantitative diameter is referred to. Typically a standardized value with defined tolerances. |
| normal operating dynamic viscosity | Number |
millipascal second | Optional | The dynamic viscosity at which a functional or physical object is expected to operate normally. |
| normal operating mass flow rate | Number |
kilogram per hour | Optional | The mass flow rate at which a functional or physical object is expected to operate normally. |
| normal operating pressure | Number |
bar gauge | Optional | A pressure at which a functional or physical object is expected to operate normally. |
| normal operating temperature | Number |
degree celsius | Optional | A temperature at which a functional or physical object is expected to operate normally. |
| orifice area calculated | Number |
square millimetre | Optional | An orifice area that is calculated. |
| relief bellows | Boolean |
— | Optional | Is a collection of items each of which is a relief bellow. |
| safety integrity level | Text |
— | Optional | A relative level of risk-reduction provided by a safety function, or to specify a target level of risk reduction |
| set pressure | Number |
bar gauge | Optional | A pressure at which an object is activated. |
| spring material specification | Text |
— | Optional | Is a specification which describes the applicable materials for one or more items. |
| test medium | Text |
— | Optional | The medium used for testing purpose. |
| test pressure | Number |
bar gauge | Optional | A pressure to which an object should be subjected to test for leakage and structural integrity. |
| upper limit operating temperature | Number |
degree celsius | Optional | A temperature that is the highest temperature at which a functional or physical object is expected to operate. |
| variable back pressure | Number |
bar gauge | Optional | A back pressure that varies due to changes in operation of one or more pressure relief valves connected into a common discharge header. |
