27、dization) 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
28、 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.The procedures used
29、 to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of
30、 the ISO/IEC Directives, Part 2 (see www.iso.org/directives).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. Details of any patent rights identified
31、during the development of the document will be in the Introduction and/or on the ISO list of patent declarations received (see www.iso.org/patents).Any trade name used in this document is information given for the convenience of users and does not constitute an endorsement.For an explanation on the

44、8:2017-03 EN ISO 2398:2016 (E)5 4 ClassificationHoses are designated as one of the following types, depending on their pressure rating.Type 1: Low pressure designed for a maximum working pressure of 1 MPa (10 bar)Type 2: Medium pressure designed for a maximum working pressure of 1,6 MPa (16 bar)Type
45、 3: High pressure designed for a maximum working pressure of 2,5 MPa (25 bar)These types can be subdivided into three classes depending on their oil resistance.Class A: Non-oil-resistantClass B: Normal oil resistanceClass C: Good oil resistanceThe types and classes above can also be further subdivid
46、ed into two categories, depending on their operating-temperature range.Categor y N-T (normal temperature): 25 C to +70 CCategor y L-T (low temperature): 40 C to +70 C5 Materials and constructionThe hose shall consist of a rubber lining, a reinforcement of natural or synthetic textile, applied by any
47、 suitable technique, and a rubber cover.The lining and cover shall be of uniform thickness, concentric to comply with the minimum thickness specified, and free from holes, porosity and other defects. The cover finish may be smooth or fabric-marked.6 Dimensions6.1 Inside diameters and tolerancesWhen
48、measured in accordance with ISO 4671, the inside diameters and their tolerances shall conform to the values specified in Table 1.DIN EN ISO 2398:2017-03 EN ISO 2398:2016 (E) 6 Table 1 Minimum and maximum inside diametersHose sizeMinimum internal diameter mmMaximum internal diameter mm4 3,25 4,755 4,25 5,756,3 5,55 7,058 7, 25 8,7510 9,25 10,7512,5 11,75 13,2516 15,25 16,7519 18,25
