Using the Cone Calorimeter to Predict FMVSS 302 Performance of Interior and Exterior Automotive Materials 2006-01-1270

Forty-eight materials from parts used inside and outside the passenger compartment of six motor vehicles were tested according to FMVSS 302. All samples passed the test although the FMVSS 302 test requirements do not apply to exterior materials. The same materials were also tested in the Cone Calorimeter (ASTM E 1354) at three heat fluxes.
The FMVSS 302 performance diagram developed earlier on the basis of Cone Calorimeter data for 18 exterior materials from two vehicles appears to have more general validity for solid plastic parts, regardless whether they are taken from locations inside or outside of the passenger compartment.
The previously-developed performance diagram is not applicable to plastic foams and fabrics. Additional criteria are proposed to predict whether a foam or fabric is likely to pass the FMVSS 302 test based on ignition time and peak heat release rate measured in the Cone Calorimeter at a heat flux of 35 kW/m2.
