Piping, Ducting and Cable Trays : Standard Component Attributes : Insulation Specification Attribute
Insulation Specification Attribute
Keywords:
ISPEC
Description:
This attribute points to an insulation Specification. It is automatically cascaded down from the Branch ISPE setting, but can also be set on an individual basis. In conjunction with the Branch TEMPERATURE attribute, the ISPE insulates the Component and the Tube from its Leave point.
Examples: 
ISPE /I500-HAV
The Current Component and Tube from its Leave p-point will be insulated according to the named Specification. (The temperature parameters required to determine insulation thickness will be obtained from the Branch element.)
ISP NULREF
The Component and Tube from its Leave p-point will be uninsulated.
Note:
If a whole Branch is to be insulated, the Branch ISPE should be set before Components are created. This setting will then cascade down to all new Components.
