2、155-2:2002 This Draft for Development, having been prepared under the direction of the Engineering Sector Policy and Strategy Committee, was published under the authority of the Standards Policy and Strategy Committee on 17 December 2002 BSI 17 December 2002 ISBN 0 580 40963 5 National foreword This
3、 Draft for Development reproduces verbatim ISO/TS 11155-2:2002. This publication is not to be regarded as a British Standard. It is being issued in the Draft for Development series of publications and is of a provisional nature because technology in this area is still being developed and this docume
4、nt provides a basis on which industry can work. It should be applied on this provisional basis, so that information and experience of its practical application may be obtained. Comments arising from the use of this Draft for Development are requested so that UK experience can be reported to the inte
5、rnational organization responsible for the Technical Specification. A review of this publication will be initiated not later than 3 years after its publication by the international organization so that a decision can be taken on its status at the end of its 3-year life. Notification of the start of
6、the review period will be made in an announcement in the appropriate issue of Update Standards. According to the replies received by the end of the review period, the responsible BSI Committee will decide whether to support the conversion into an international standard, to extend the life of the Tec
7、hnical Specification for another 3 years or to withdraw it. Comments should be sent in writing to the Secretary of BSI Subcommittee MCE/21/2, Air filters for air supply to I.C. engines and compressors not on aircraft, at British Standards House, 389 Chiswick High Road, London W4 4AL, giving the docu
8、ment reference and clause number and proposing, where possible, an appropriate revision of the text. A list of organizations represented on this committee can be obtained on request to its secretary. Cross-references The British Standards which implement international publications referred to in thi

16、led Copy, (c) BSI IS/OTS -55111:22002(E) vi I SO 2002 All irthgs ersedevr Foreword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO te
17、chnical 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 take part in the work. ISO collaborates close
18、ly 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 3. The main task of technical committees is to prepare International Standards. Draft
19、 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. In other circumstances, particularly when there is an urgent market requiremen
20、t for such documents, a technical committee may decide to publish other types of normative document: an ISO Publicly Available Specification (ISO/PAS) represents an agreement between technical experts in an ISO working group and is accepted for publication if it is approved by more than 50 % of the
21、members of the parent committee casting a vote; an ISO Technical Specification (ISO/TS) represents an agreement between the members of a technical committee and is accepted for publication if it is approved by 2/3 of the members of the committee casting a vote. An ISO/PAS or ISO/TS is reviewed after
22、 three years with a view to deciding whether it should be confirmed for a further three years, revised to become an International Standard, or withdrawn. In the case of a confirmed ISO/PAS or ISO/TS, it is reviewed again after six years at which time it has to be either transposed into an Internatio
23、nal Standard or withdrawn. Attention is drawn to the possibility that some of the elements of this part of ISO/TS 11155 may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO/TS 11155-2 was prepared by Technical Committee ISO/TC 22,
24、Road vehicles, Subcommittee SC 7, Injection equipment and filters for use on road vehicles. ISO/TS 11155 consists of the following parts, under the general title Road vehicles Air filters for passenger compartments: Part 1: Test for particulate filtration Part 2: Test for gaseous filtration Annex A
