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.

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. 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 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 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 ISO’s 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 third edition cancels and replaces the second edition (ISO 6808:1999), which has been technically

revised with the following changes:
— Throughout the document: Nominal bore was changed to hose size.
— Throughout the document: ISO 1817 Oil No. 3 was changed to IRM 903 oil.

— ISO 471, ISO 1746, and ISO 4672 were replaced by ISO 23529, ISO 10619-1, and ISO 10619-2,

respectively.
— Terms and definitions clause was added.
— Type 1 and Type 2 maximum working pressures at 45 °C were corrected.
— Hose construction for electrical bonding was updated.
— Tables 4 and 5: Note b was added.
— 7.2 and Table 5: Changed 55 °C to 45 °C.
— 9.3: Electrical bonding was redefined.
— 9.4: Added electrical wall resistance clause.

Introduction

This International Standard has been prepared to provide minimum acceptable requirements for

the satisfactory performance of polymer-reinforced thermoplastics hoses for suction and discharge

applications, conveying kerosene, heating oil, diesel fuel, and lubricating oils. These hoses are neither

suitable for conveying automotive or aviation fuel nor suitable for metered delivery of any liquid.

The list of hose sizes given in Tables 1 and 2 is not intended to be restrictive and will not preclude the

manufacture of sizes outside the preferred-number range (the basis of the tables) and which might be

the subject of individual national standards.

WARNING — Persons using this International Standard should 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 safety and

health practices and to ensure compliance with any national regulatory conditions.

1 Scope

This International Standard specifies the requirements for two types of polymer-reinforced

thermoplastics hose and hose assembly for suction and discharge applications with kerosene, heating

oil, diesel fuel, and lubricating oils in the temperature range –10 °C to +45 °C.

NOTE The hoses can be stored in a static condition at –30 °C to +65 °C without damage by climatic conditions.
