Description / Abstract:
1. 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.
1.1 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.
1.2 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.
