New Guide for General Guidelines for Measuring Fire Extinguishing Agent Concentrations in Powerplant Compartments
1. Scope
This standard practice provides guidance for fire extinguishing agent concentration testing used in determining the distribution and concentration of fire extinguishing agents when discharged in an aircraft
powerplant compartment. The material was developed through open consensus of international experts in
general aviation and incorporates guidance from FAA AC 20-100 as well as other previously accepted practices.

Rationale
Halon is being phased out. This guide will be used to provide standards for the fire suppression concentration testing of non-Halon agents that will replace Halon in Powerplant fire suppression systems. The guide will provide the previously accepted test methodologies (sourced from AC 20-100, AC 23-16A and other relevant CAA advisory material). The initial issue of the guide will be published with the historical standards for Halon agents. Revisions of this guide will be published when concentration standards have been developed for alternative agents.
The title and scope are in draft form and are under development within this ASTM Committee.
