12、 BS ISO 7654:1998 BSI 05-1999iii 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 technical committees. Each member body inte
13、rested 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 closely with the International Electrotechnica
14、l Commission (IEC) on all matters of electrotechnical 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 least 75 % of the member bodies casting a vote. In
15、ternational Standard ISO 7654 was prepared by Technical Committee ISO/TC 22, Road vehicles, Subcommittee SC 7, Injection equipment and filters for use on road vehicles. This third edition cancels and replaces the second edition (ISO 7654:1991), which has been technically revised. Annex A forms an in
16、tegral part of this International Standard. Annex B is for information only. Descriptors: Road vehicles, internal combustion engines, diesel engines, fuel filters, form specifications, connecting dimensions, mounting dimensions, dimensional tolerances.

18、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 clause 2. The alternative filter design is specified in Annex A and should be used if
19、an inner sealing is required. The corresponding filter heads are specified in ISO 7310, ISO 7311 and ISO 7577 (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 tolerances of the filter shall be
20、 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 dimension 0,5 mm min. shown in X shall be measured after tightening the fil
21、ter in accordance with the filter manufacturers recommendations. In cases where moulded sealing rings are used, this dimension may be 0; 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 design shall be identif
22、ied 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 fuel filter; b) size o
23、f 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.

25、BS ISO 7654:1998 BSI 05-19993 Annex A (normative) Spin-on filters with inner sealing In cases where an additional sealing ring (inner sealing) at the connecting thread is required, the alternative design shown in Figure A.1 and Figure A.2 should be used by mutual agreement between manufacturer and u
26、ser. 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 shall be at the discretion of the manufacturer, depending on material and shape. The shape of the sealing
27、 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 be so joined as to necessitate the replacement of all three parts simultaneously. Figure A.1 Dimensions
