Definition: Insulated wagon

Category: Transport

Covered wagon the body of which is built with insulating walls, doors, floor and roof, to limit heat exchange between the interior of the wagon and the outside so that the overall coefficient of heat transfer (K coefficient), allows the equipment to be assigned to one or other of the following two categories:

- IN = Normally insulated: characterized b - y a K coefficient equal to or less than 0.7 W/m 2°C
- IR = Heavily insulated: characterized by a K coefficient equal to or less than 0.4 W/m 2°C

Covered wagon of which the body is built with insulating walls, doors, floor and roof, by which the heat exchanges between the inside and outside of the body can be so limited that the overall coefficient of heat transfer (K coefficient), is such that the equipment is assignable to one or other of the following two categories:

IN = Normally insulated equipment - characterised by a K coefficient equal to or less than 0.7 W/m² °C
IR = Heavily insulated equipment - characterised by a K coefficient equal to or less than 0.4 W/m² °C
