23、33:2017 (E)3 ForewordISO (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 f
24、or 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
25、 all matters of electrotechnical standardization.The procedures used 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.
26、 This document was drafted in accordance with the editorial rules of 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
27、 or all such patent rights. Details of any patent rights identified 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 use

31、ers, between cover and outer lamination (thin layer of material outside the cover for protection) and between lining and inner lamination (thin layer of material inside the lining to reduce permeation of fluid into the lining). It covers all bore sizes and the following types of hose construction: w
32、oven textile fabric; braided textile fabric; knitted textile fabric; circular-woven textile fabric; textile spiral; textile cord; wire braid; wire spiral; hoses containing a supporting helix.Adequate adhesion between the various components of a hose is essential if it is to perform satisfactorily in
33、 service.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

37、etween reinforcement layers, between cover and outer lamination and between lining and inner lamination is measured under specified conditions.5 Apparatus5.1 GeneralA test machine having the following characteristics is required:5.2 Test machineThe machine shall be power driven, equipped with a suit
38、able dynamometer, capable of maintaining a substantially constant rate of traverse of the moving head during the test and fitted with an autographic recorder. It shall comply with the requirements for class 0,5 or 1 of ISO 5893.An inertialess dynamometer shall be used.5.3 GripsThe grips shall be cap
39、able of holding the test piece without slippage.Self-tightening grips are recommended.For strip test pieces, provision shall be made to maintain the strip in the appropriate plane of the grips during the test, for example, by attaching sufficient weights to the free end of the test piece or by fitti
40、ng a supporting plate, coated with a low-friction material, such as polytetrafluoroethylene (PTFE), to the non-driven grip.5.4 MandrelFor testing ring test pieces (type 6 and type 8), a mandrel shall be provided that is a close sliding fit in the test piece. This mandrel shall be capable of being fi
41、tted into the driven head of the machine so that it will rotate freely during the test.6 Test pieces6.1 Types of test piece6.1.1 GeneralEight types of test piece are specified to cover the range of hose constructions and bore sizes normally encountered (see Figures 1 to 8).6.1.2 Type 1Strip, cut fro

43、.5 Type 4Strip, 160 mm half the hose circumference or 10 mm, whichever is smaller.6.1.6 Type 5Strip, 160 mm long half the hose circumference.6.1.7 Type 6Ring, 35 mm 2 mm wide.6.1.8 Type 7Strip, cut along a reinforcing helix, 25 mm 0,5 mm wide or the maximum obtainable.6.1.9 Type 8Ring, 25 mm 0,5 mm
44、wide.6.2 Test piece selectionUnless specified in the particular product standard or otherwise agreed between the interested parties, the type of test piece shall be selected from Table 1. Results obtained with different test pieces and/or hoses of the same construction but of different diameters are

47、 Type 3, 6 or 8 Type 3, 6 or 8aIf the determination of adhesion is affected by difficulty in obtaining a cleanly separating interface because of fraying of the yarns, indicate this in the test report.bDetermination is impracticable below 12,5 mm bore size since insufficient test piece width is avail
48、able.cDetermination is impracticable since the wire braid or spiral layers tend to disintegrate and the result is in any case significantly affected by the forces required to bend the wires.DIN EN ISO 8033:2017-04 EN ISO 8033:2017 (E)7 Hose construction Adhesion betweenHose nominal bore size, dmmd 20 20 d 50 50 dWire braidWire spiralLining a
