The work of preparing Interna
8、tional 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
9、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 Directives,
10、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 of t
11、he 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 declarations
12、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 IS
13、Os adherence to the WTO principles in the Technical Barriers to Trade (TBT) see the following URL: Foreword - Supplementary information The committee responsible for this document is ISO/TC 45, Rubber and rubber products, Subcommittee SC 1, Rubber and plastics hoses and hose assemblies. This second
14、edition cancels and replaces the first edition (ISO 13363:2004), which has been technically revised with the following changes: class B hoses to be of rubber materials only; the abrasion test has been removed until a new abrasion test standard has been developed and the corresponding International S
15、tandard published. It also incorporates the Technical Corrigendum ISO 13363:2004/Cor.1:2008.iv ISO 2016 All rights reserved INTERNATIONAL ST ANDARD ISO 13363:2016(E) Rubber and plastics hoses for marine-engine wet-exhaust s y st ems Specification WARNING Persons using this International Standard sho
16、uld be familiar with normal laboratory practice. This International Standard does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user to establish appropriate health and safety practices and to ensure compliance with any national r
17、egulatory conditions. 1 Scope This International Standard specifies requirements for three types and two classes of hose. The hoses are intended for use in marine-engine wet-exhaust systems (where the exhaust gases are mixed with the discharge of cooling water). It does not apply to outboard motor/p
18、ersonal water craft. The three types are the following: type 1: a softwall hose, made of oil-resistant material, with a synthetic-fabric reinforcement; type 2: a hardwall hose, made of oil-resistant material, with a synthetic-fabric reinforcement with a helical wire embedded in it; type 3: a hose or
19、 tube (flexible connector), made of oil-resistant material, with or without a reinforcement or cover, intended for use in short lengths in locations where the connector is protected from mechanical damage. The two classes are the following: class A: intended for diesel engines; class B: intended for
20、 petrol engines and for diesel engines with a very high exhaust temperature. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
