It supersedes BS4552-3:1992 which is withdrawn. The UK participation in its preparation was entrusted
3、 by Technical Committee MCE/21, Filters for gases and liquids, to SubcommitteeMCE/21/6, Filters for volatile liquid fuels, which has the responsibility to: aid enquirers to understand the text; present to the responsible international/European committee any enquiries on the interpretation, or propos
4、als for change, and keep the UK interests informed; monitor related international and European developments and promulgate them in the UK. A list of organizations represented on this subcommittee can be obtained on request to its secretary. Cross-references The British Standards which implement inte

A British Standard does not purport to inc
6、lude all the necessary provisions of a contract. Users of British Standards are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations. Summary of pages This document comprises a front cover, an inside front cover, page

10、e 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 technical committees. Each member body interested in a subject for which a technical committ
11、ee 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 closely with the International Electrotechnical Commission (IEC) on all matters of electrotechn
12、ical standardization. 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 least75% of the member bodies casting a vote. International Standard ISO7654 was prepared by Techni
13、cal Committee ISO/TC22, Road vehicles, Subcommittee SC7, Injection equipment and filters for use on road vehicles. This third edition cancels and replaces the second edition (ISO7654:1991), which has been technically revised. Annex A forms an integral part of this International Standard. Annex B is
14、for information only. Descriptors: Road vehicles, internal combustion engines, diesel engines, fuel filters, form specifications, connecting dimensions, mounting dimensions, dimensional tolerances.iv blankBSISO7654:1998 BSI 05-1999 1 1 Scope This international Standard specifies the mounting and con
15、necting dimensions for spin-on fuel filters, with and without an inner sealing, to be used with diesel (compression-ignition) engines. The preferred design of spin-on fuel filters are those without an inner sealing, and they are specified in clause2. The alternative filter design is specified in Ann
16、ex A and should be used if an inner sealing is required. The corresponding filter heads are specified in ISO7310, ISO7311 and ISO7577 (see Annex B). 2 Dimensions and tolerances Details not specified in this International Standard are left to the manufacturers choice. 2.1 The dimensions and tolerance
17、s of the filter shall be in accordance with Figure 1. The shape of the sealing ring shown in X shall be such that effective sealing is ensured. The dimensions of the compressed sealing ring shall be within the sealing surface shown in Figure 2. The dimension0,5mmmin. shown in X shall be measured aft
18、er tightening the filter in accordance with the filter manufacturers recommendations. In cases where moulded sealing rings are used, this dimension may be0; i.e.,metal contact between the sealing surface to which the filter is attached and the face of the spin-on filter is allowed. This special desi
19、gn shall be identified on the filter with necessary fitting instructions. 2.2 The dimensions and tolerances of the sealing surface and connecting thread shall be in accordance with Figure 2. 3 Marking Spin-on fuel filters may optionally be marked as follows: a) designation of filter type: diesel fue
20、l filter; b) size of connecting thread, for example,M16 1,5; c) instructions for installation. The appearance and position of this marking on the filter body are left to the discretion of the manufacturer.

22、e design shown in Figure A.1 and Figure A.2 should be used by mutual agreement between manufacturer and user. All other dimensions and specifications not shown in Figure A.1 and Figure A.2 are in accordance with Figure 1 and Figure 2 respectively. The free height of sealing ring shown in Figure A.1
23、shall be at the discretion of the manufacturer, depending on material and shape. The shape of the sealing rings shall be such that effective sealing is ensured. The dimensions of the compressed inner sealing ring shall be within the sealing surface shown in Figure A.2. Filter and sealing rings shall
24、 be so joined as to necessitate the replacement of all three parts simultaneously. Figure A.1 Dimensions of filter with inner sealing d d s M16 1,5 22,5max. M24 1,5 30,5max.
