This part of ISO 15859 specifies limits for the composition of kerosine and establishes the sampling and test requirements applicable for the verification of the kerosine composition. This part of ISO 15859 is applicable to kerosine propellant intended for use in fuel in propellant systems of space systems as well as in both flight hardware and ground support facilities, systems and equipment. It may be applied to influent or effluent kerosine. This part of ISO 15859 is applicable to any sampling operation required to ensure that, when the fluid enters the launch vehicle or spacecraft, the fluid composition complies with the limits provided hereafter or with any technical specification agreed to for a particular use.
