API RP 1543:2009

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 to 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. Mandatory requirements in this standard are designated by the word 'shall.' Recommendations are designated by the word 'should.' Optional items are designated by the word 'may.' This standard incorporates by reference a number of other standards and RPs that need to be referred. The distinction between mandatory, recommended and optional provisions in the referenced documents are not changed by nature of their reference in this standard. The values stated for this standard are in U.S. (USC) customary units.
