T.1.6 Thermal Protection

T.1.6.1 When seated in the normal driving position, sufficient heat insulation must be provided to ensure that the driver will not contact any metal or other materials which may become heated to a surface temperature above 60°C.

T.1.6.2 Insulation may be external to the cockpit or incorporated with the Driver’s Seat or Firewall.

T.1.6.3 The design must address all three types of heat transfer between the heat source (exhaust pipe, coolant hose/tube) and the panel that the driver could contact (seat or floor):

a. Conduction Isolation by one of the following:

 No direct contact between the heat source and the panel

 A heat resistant, conduction isolation material with a minimum thickness of 8 mm between the heat source and the panel.

b. Convection Isolation by a minimum air gap of 25 mm between the heat source and the panel

c. Radiation Isolation by one of the following:

 A solid metal heat shield with a minimum thickness of 0.4 mm

 Reflective foil or tape when combined with conduction insulation.
