T3/T4
Temperature range (3,000 h)
T3 -40 °C to +125 °C
T4 -40 °C to +150 °C
ISO 6722
Masterbatch designed to colour cables of temperature class T3 and T4. Cables of class T3 are highly exposed to significant heat from radiation sources and are expected to function under environmental temperatures ranging from -40 to +125 °C.
Their typical application is close to the engine. Cables of class T4 are exposed to considerable heat from radiation and conduction and are expected to function under environmental temperatures ranging from -40 to +150 °C. Their typical application is in the engine oil circuit.
