Organization: SAE
Publication Date: 1 October 2020
Status: active
Page Count: 12
scope:

This SAE Recommended Practice establishes equipment and procedures for testing spark arresters used on medium-size, single-position internal combustion engines, normally used in transportable, stationary, and vehicular applications, such as highway trucks, agricultural tractors, industrial tractors, other mobile equipment, and motorcycles. This document provides two methods of testing (laboratory testing and engine testing) which may be used to evaluate a spark arrester. It also includes special requirements for screen type devices and an endurance test procedure for screen type spark arresters.

Purpose-

This document provides a method of testing to evaluate spark arresters for compression ignition or spark ignition internal combustion engines. It is not intended to establish the performance level required for adequate fire protection, nor does it cover applications requiring flame arresting, exhaust gas cooling, or isolation from explosive gases.

Spark Arrester Application-

Spark arresters qualified by an engine test should be used on only engines of the same design and size (or smaller) and which do not exceed the calculated flow rate of the test engine by more than 15%. Calculated flow rate shall be determined at maximum power engine speed or at maximum governed engine speed, whichever is lower.

This document has been established to cover most medium sizes and type of engines and engine applications. Arresters tested under this procedure should not be used above their rated flow unless tested and found to be adequately effective at the intended flow.
