API RP 1543 (R2019)

Aviation fuels pass through a variety of storage and handling facilities from refinery to airport. As aviation fuels are stored and transported in storage and transportation systems where contact with non-aviation products may occur (e.g. multi product pipelines, non dedicated ship or barge) a fuel quality monitoring program is required in addition to equipment, operating, inspection and maintenance standards. The purpose of this practice is to ensure the fuel remains on specification. This recommended practice (RP) was developed to provide guidance on the development of an aviation fuel monitoring and testing program (fuel quality monitoring program) for aviation fuel from point of manufacture to delivery the airport. " Proper handling" entails documenting and testing aviation fuel quality as product is transported throughout the supply chain to maintain the original product specification.
