Abstract

Specifies the maximum surface temperatures of motor vehicle exhaust systems to minimize the likelihood of bush fires, and includes the test method for determining the surface temperature. The test method simulates hard driving conditions which are followed by a cooling down period during which temperatures of the exhaust system surfaces are recorded at specific intervals.

Scope

This Standard specifies the maximum surface temperatures of vehicle exhaust systems to minimize the likelihood of grass and forest fires due to contact of vegetation with the exhaust system. The method for determining the surface temperature is given in Appendix A.
