The work of preparing International Sta

13、ndards 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, governmental and non-governmental, in liaison with ISO, also

14、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 Directives, Part 2. The main task of technical committees

15、 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 bodies casting a vote. Attention is drawn to the possibi

16、lity 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 15859-1 was prepared by Technical Committee ISO/TC 20, Aircraft and space vehicles, Subcommittee SC 14, Space systems and operatio

17、ns. ISO 15859 consists of the following parts, under the general title Space systems Fluid characteristics, sampling and test methods: Part 1: Oxygen Part 2: Hydrogen Part 3: Nitrogen Part 4: Helium Part 5: Nitrogen tetroxide propellants Part 6: Monomethylhydrazine propellant Part 7: Hydrazine prope

19、he 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 of launch vehicles, spacecraft and ground support equipment. The fluid compositio

20、n 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. The fluid sampling and test methods are acceptable methods for verification of the

21、fluid composition limits. BSISO158591:2004INTENRATIONAL TSANDADR IS-95851 O1:(4002E)1Space systems Fluid characteristics, sampling and test methods Part 1: Oxygen 1 Scope This part of ISO 15859 specifies the limit values for the composition of oxygen and establishes the sampling and test requirement

This part of ISO 15859 is applicable to oxygen, used in both flight hardware and ground facilities, systems and equipment, of the following types and grades. Type I: gaseous Grade A: standard, purging/pressurization, Grade CB: crew breathi

23、ng, Grade F: fuel-cell; Type II: liquid Grade A: oxidizer, Grade B: oxidizer, Grade F: fuel-cell. This part of ISO 15859 is applicable to influents only within the specified limits herein. This part of ISO 15859 is applicable to any sampling operation required to ensure that, when the fluid enters t

24、he launch vehicle or spacecraft, the fluid composition 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.

BSISO158591:2004ISO 15859-1:2004(E) 35 Procurement The types and grades of oxygen specified in Clause 1 should be pro

32、cured in accordance with an applicable national or international standard. 6 Fluid sampling CAUTION Oxygen is an oxidant. Human contact with liquid oxygen will result in severe injury. Care should be taken in the handling and storage of liquid oxygen to prevent contact with the human body and with m

33、aterials that are not compatible with oxygen. Care should also be taken to prevent high concentrations of gaseous oxygen in confined spaces where ignition of combustible materials may occur. 6.1 Plan In order to ensure that the fluid composition complies with the limits specified in this part of ISO

34、 15859, a fluid sampling plan should be established by all the involved operators, 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 spec

35、ify the sampling points, the sampling procedures, the sampling frequency, the sample 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 oxygen delive

36、red to the flight vehicle interface shall be sampled and verified by the supplier responsible for providing the oxygen 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 c

37、ustomer. 6.3 Sampling points Unless otherwise specified, sampling shall be conducted at the fluid storage site or the flight vehicle interface. 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 q

38、uantity in a single sample container shall be sufficient to perform the analysis for the limiting characteristics. 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 cond

39、itions. BSISO158591:2004ISO 15859-1:2004(E) 4 6.6 Number of samples The number of samples shall be in accordance with one of the following: a) one 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 t

40、he applicable sampling plan, the fluid storage container shall not be refilled after the sample is taken. 6.8 Gaseous samples Gaseous samples shall be a typical specimen from the gaseous oxygen supply. Samples shall be obtained in accordance with one of the following. a) By filling the sample contai

41、ner and storage containers at the same time, on the same manifold, and under the same conditions and with the same procedure. b) By withdrawing a sample from the supply container through a suitable connection into the sample container. No pressure regulator shall be used between the supply and the s

42、ample containers. (Suitable valves are permissible.) For safety reasons, the sample container and sampling system shall have a rated service pressure at least equal to the pressure in the supply container. c) By connecting the container being sampled directly to the analytical equipment using suitab

43、le pressure regulation to prevent over-pressurizing this equipment. 6.9 Liquid samples (vaporized) Vaporized liquid samples shall be a typical specimen from the liquid oxygen supply. Samples shall be obtained by flowing liquid from the supply container into or through a suitable container in which a

44、 representative liquid sample is collected and then completely vaporized. 6.10 Rejection When any sample of the fluid tested in accordance with Clause 7 fails to conform to the requirements specified in this part of ISO 15859, the fluid represented by the sample shall be rejected. Disposal of the re

45、jected fluid shall be specified by the customer. 7 Test methods 7.1 General The supplier will ensure, by standard practice, the quality level of oxygen. If required, alternate test methods are described in 7.3 to 7.16. Other test methods not listed in this part of ISO 15859 are acceptable if agreed

46、upon between the supplier and the customer. These tests are a single analysis or a series of analyses performed on the fluid to ensure the reliability of the storage facility to supply the required quality level. This can be verified by analysis of representative samples of the fluid from the facili

47、ty at appropriate intervals as agreed upon between supplier and the customer. Tests may be performed by the supplier or by a laboratory agreed upon between the supplier and the customer. The analytical requirements for the tests shall include the determination of all limiting characteristics of oxyg

BSISO158591:2004ISO 15859-1:2004(E) 57.2 Parameters of analysis The parameters for analytical techniques contained in 7.3 to 7.16 are the following: a) purity and impurity contents shall be expressed as a percentage by volume (volume fraction, %) unless otherwise noted; b) calibration gas standa

49、rds containing the applicable gaseous components may be required to calibrate the analytical instruments used to determine the limiting characteristic levels of the fluid; c) if required by the customer, the accuracy of the measuring equipment used in preparing these standards shall be traceable to an est
