Organization: SAE
Publication Date: 1 October 2020
Status: active
Page Count: 9
scope:

This SAE Recommended Practice establishes equipment and procedures for the evaluation of the effectiveness and other performance characteristics of spark arresters or turbochargers used on the exhaust system of large engines normally used in a railroad locomotive, stationary power plant, and other similar applications. This document does not cover applications requiring flame arresting, exhaust gas cooling, or isolation from explosive gases. Two test methods are presented: a laboratory test using ambient air (cold test) and an engine test using exhaust gases (hot test). The hot test is preferred.

Arresters tested by the provisions of this document can be expected to perform as tested when tilted no more than 45 degrees from their normal position. Test results from a spark arrester or turbocharger evaluated by the hot test can be applied to different engines of similar design, provided the data shows it to be effective in the applicable flow ranges.

Certain design and performance characteristics, which represent current requirements by regulatory agencies for qualification and approval under this document, are listed in Appendix A.

Purpose-

The purpose of this document is to provide a standard method of testing to evaluate spark arresters or turbochargers as spark arresters for use with large compression ignition internal combustion engines.

This document provides a method to evaluate the effectiveness of various spark arresters, but is not intended to establish the performance level required for adequate fire protection (see Appendix A).
