Rationale: This Aerospace Recommended Practice (ARP) consists of methodologies for the measurement of non-volatile particulate matter (nvPM) emissions sampled at the exit plane of aircraft gas turbine engines. The methods describe means of sampling and measuring particle mass concentration, particle number concentration and reporting of emissions indices through the use of an appropriate sampling system and instrumentation that goes beyond the measurements of visible obscuration as described in ARP1179 for Smoke Number (SN). This ARP allows for repeatable and traceable measurements of nvPM mass and number concentrations at the end of the prescribed sampling system, and it provides technical details for the measurement of nvPM emissions required for engine certification consistent with ICAO Annex 16 Volume II (see 2.1.3.14).1
