本SAE推荐规程规定了用于测试中型单位置内燃机上火花熄灭器的设备和程序，这些内燃机通常用于可运输、固定和车辆应用，如公路卡车、农业拖拉机、工业拖拉机、其他移动设备和摩托车。本文件提供了两种测试方法（实验室测试和发动机测试），可用于评估火花塞。它还包括屏蔽型装置的特殊要求和屏蔽型火花放电器的耐久性试验程序。

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.
