Product Code:SAE ARP4418
Title:Procedure for Sampling and Measurement of Engine Generated Contaminants in Bleed Air Supplies From Aircraft Engines Under Normal Operating Conditions
Issuing Committee:E-31 Aircraft Exhaust Emissions Measurement Committee
Scope: The following individual engine compressor generated contaminants are addressed by this SAE Aerospace Recommended Practice (ARP): a. carbon dioxide; b. hydrogen fluoride; c. organic material; d. carbon monoxide; e. acrolein; f. respirable particles; g. oxides of nitrogen; and h. formaldehyde. For reference purposes, information is also given on the current maximum allowable engine bleed air concentration limits for each of these contaminants, as stated in the latest issue of AIR4766. Recommended techniques for the sampling and sample transfer are given, together with the specific analytical methodology and acceptable alternate referenced analytical methodology for each of the above contaminants. Recommendations are also made for an engine test format and for the allowance of ambient air quality on the engine measured contaminant concentration levels. The previous list of contaminants are considered appropriate for the certification and passenger safety requirements of both civil and military aircraft.
