This international Standard specifies the mounting and connecting 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 clause 2. The alternative filter design is specified in annex A and should be used if an inner sealing is required.

The corresponding filter heads are specified in ISO 7310, ISO 7311 and ISO 7577 (see annex B).
