14、ber bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmen
15、tal and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Direc
16、tives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodi
17、es casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 15859-8 was prepared by Technical Committee ISO/TC 20, Aircraft and space vehi
18、cles, Subcommittee SC 14, Space systems and operations.

20、h site may involve a number of operators and supplier/customer interfaces, from the fluid production plant to the delivery to the launch vehicle or spacecraft. The purpose of ISO 15859 is to establish uniform requirements for the components, sampling and test methods of fluids used in the servicing
21、of launch vehicles, spacecraft and ground support equipment. The fluid composition limits specified are intended to define the purity and impurity limits of the fluid for loading into the launch vehicle or spacecraft. The fluid sampling and test methods are intended to be applied by any operator. Th
22、e fluid sampling and test methods are acceptable methods for verification of the fluid composition limits.

23、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 syste
24、ms 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 co
25、mposition complies with the limits provided hereafter or with any technical specification agreed to for a particular use. 2 Normative references The following referenced documents are indispensable for the application of this document.

42、s, from the production to the space vehicle interface, and approved by the final user. Sampling activities and test methods shall comply with all safety regulations and rules applicable to that task. This plan shall specify the sampling points, the sampling procedures, the sampling frequency, the sa
43、mple size, the number of samples, the test methods, and the responsibilities of any involved operator. 6.2 Responsibility for sampling Unless otherwise provided in an applicable technical specification, the kerosine delivered to the flight vehicle interface shall be sampled and verified by the suppl
44、ier responsible for providing the kerosine to the flight vehicle. The supplier may use his/her or any other resources suitable for the performance of the verification tests specified herein unless otherwise directed by the customer. 6.3 Sampling points Unless otherwise specified, sampling shall be c
45、onducted at the fluid storage site. 6.4 Sampling frequency Sampling shall be performed annually or in accordance with a time agreed upon by the supplier and the customer. 6.5 Sample size The quantity in a single sample container shall be sufficient to perform the analysis for the limiting characteri
46、stics. If a single sample does not contain a sufficient quantity to perform all of the analyses for the required quality verification test, additional samples shall be taken under similar conditions. 6.6 Number of samples The number of samples shall be in accordance with one of the following: a) one
47、 sample per storage container; b) any number of samples agreed upon by the supplier and the customer. 6.7 Storage container Unless otherwise provided by the applicable sampling plan, the fluid storage container shall not be refilled after the sample is taken.
