Your comments on this draft are invited and will assist in the preparation of the consequent standard. Comments submitted will be reviewed by the relevant BSI committee before sending the consensus UK vote and comments to the international secretariat, which will then decide appropriate action on the draft and the comments received. If no comments are received to the contrary, then the UK will approve this draft. If the international standard is approved, it is possible the text will be published as an identical British Standard. UK Vote Please indicate whether you consider the UK should submit a negative (with reasons) or positive vote on this draft. Submission The guidance given below is intended to ensure that all comments receive efficient and appropriate attention by the responsible BSI committee. Annotated drafts are not acceptable and will be rejected. All comments must be submitted, preferably electronically, to the Responsible Committee Secretary at the address given on the front cover. Comments should be compatible with Version 6.0 or Version 97 of Microsoft® Word for Windows, if possible; otherwise comments in ASCII text format are acceptable.

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 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 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 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 possibility 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. International Standard ISO 12151-1 was prepared by Technical Committee ISO/TC 131, Fluid power systems, Subcommittee SC 4, Connectors and similar products and components. This second edition would cancel and replace the first edition (ISO 12151-1:1999), which would have been technically revised. ISO 12151 consists of the following parts, under the general title Connections for hydraulic fluid power and general use Hose fittings: Part 1: Hose fittings with ISO 8434-3 O-ring face seal ends Part 2: Hose fittings with ISO 8434-1 and 8434-4 24 degree cone connector ends with O-rings Part 3: Hose fittings with ISO 6162-1 or ISO 6162-2 flange ends Part 4: Hose fittings with ISO 6149-2 and ISO 6149-3 stud ends Part 5: Hose fittings with ISO 8434-2 37 degree flared ends Part 6: Hose fittings with ISO 8434-6 60 degree cone ends Annex A of this part of ISO 12151 is for information only.

NOTE 1 Materials other than carbon steel may be supplied as agreed between the manufacturer and user. NOTE 2 For hose fittings used in hydraulic and pneumatic braking systems on road vehicles (as defined in the scope of ISO/TC 22), see ISO 4038, ISO 4039-1 and ISO 4039-2. These hose fittings (see Figure 1 for a typical example) are for use in hydraulic fluid power systems with hose that meets the requirements of the respective hose standards and in general applications with suitable hose.
