This SAE Recommended Practice establishes equipment and test procedures for determining the performance of spark arrester exhaust systems of multiposition engines (< 19 kW) used in portable applications, including hand-held, hand-guided, and backpack mounted devices. It is not applicable to spark arresters used in vehicles or stationary equipment. This document provides a method of evaluating the potential of multiposition small engine exhaust systems to ignite vegetative fuels.
