1 BRITISH STANDARD BS EN ISO 1307:2008 Rubber and plastics hoses Hose sizes, minimum and maximum inside diameters, and tolerances on cut-to-length hoses ICS

2 National foreword This British Standard is the UK implementation of EN ISO 1307:2008. It is identical to ISO 1307:2006. It supersedes BS EN ISO 1307:1996 which is withdrawn. The UK participation in its preparation was entrusted to Technical Committee PRI/66, Rubber and plastics tubing, hoses and hose assemblies. A list of organizations represented on this committee can be obtained on request to its secretary. This publication does not purport to include all the necessary provisions of a contract. Users are responsible for its correct application. Compliance with a British Standard cannot confer immunity from legal obligations. This British Standard was published under the authority of the Standards Policy and Strategy Committee on 29 February 2008 Amendments/corrigenda issued since publication Date Comments BSI 2008 ISBN

7 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 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. ISO 1307 was prepared by Technical Committee ISO/TC 45, Rubber and rubber products, Subcommittee SC 1, Hoses (rubber and plastics). This fourth edition cancels and replaces the third edition (ISO 1307:1992), which has been technically revised. The revision includes classifying the hoses by type according to the manufacturing process, adding additional sizes, and changing the inside-diameter tolerances to minimum and maximum dimensions to be consistent with the latest hose standards. iii

9 Rubber and plastics hoses Hose sizes, minimum and maximum inside diameters, and tolerances on cut-to-length hoses 1 Scope This International Standard specifies the sizes of rubber and plastics hoses and the minimum and maximum inside diameters permitted for each hose size. For this purpose, hoses are divided into four types according to the process by which they are manufactured. The standard also specifies tolerances on cut-to-length rubber and plastics hoses for industrial and automotive applications. This standard is intended to be used with the relevant hoses product standard unless there is justification for using a different hose size or unless a hose size needs a different inside-diameter range for a particular application. 2 Hose sizes and ID tolerances by manufacturing type The sizes of rubber and plastic hoses and their respective inside-diameter ranges shall be in accordance with Table 1. Four types are specified, according to the process used to manufacture them: type A: hoses built using a rigid mandrel for inside-diameter control; type B: hoses built using a flexible mandrel for inside-diameter control (plus plastic hydraulic hoses made with or without a mandrel); type C: hoses built without using a mandrel (non-mandrel-built); type D: flexible extruded plastics hoses (type D does not include spiral-reinforced plastics suction and discharge hoses, which are classified as type C). 1
