The work of preparing I

20、nternational 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

21、 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 to develop this document and those intended for its further maintenance are described in the ISO/IEC Directi

22、ves, 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 the ISO/IEC Directives, Part 2 (see www.iso.org/directives).Attention is drawn to the possibility that some

23、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 during the development of the document will be in the Introduction and/or on the ISO list of patent declarati

24、ons 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 meaning of ISO specific terms and expressions related to conformity assessment, as well as information about

26、edition cancels and replaces the third edition (ISO 5774:2006), of which it constitutes a minor revision.The minor changes are as follows: Clause 2 has been updated: ISO 1746, ISO 4672 and ISO 11758 have been deleted and replaced by ISO 10619-1, 10619-2 and ISO 30013. Pressures have been specified i

27、n MPa and bar (with the units stated) and Table 5 has been amended accordingly. Also Clause 10 (Marking) has been slightly modified to make the information more complete. The term “type approval” has been replaced by “type test”. The error in Annex B, where, in the column “routine testing”, the proo

28、f pressure test was marked N.A. has been corrected. Proof pressure testing for each length of finished hose supplied has become normative as standard for nearly all other hose product standards. Also Annex C (informative) has been amended (this annex is for guidance only) and the recommendation for

29、production acceptance testing on tensile strength/elongation at break of lining and cover, change in length and diameter at proof pressure, adhesion, bending test has been changed from “N.A.” to “X”, in order to monitor the quality of manufacturers production more efficiently.iv ISO 2016 All rights
