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 of the voluntary nature of standards, the meaning of ISO specific terms and

expressions related to conformity assessment, as well as information about ISO's adherence to the

World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT), see www .iso .org/

iso/ foreword .html.

This document was prepared by Technical Committee 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 13775-1:2015), which has been

technically revised.
The main changes compared to the previous edition are as follows:
— normative references updated;
— addition of clause 3.
A list of all parts in the ISO 13775 series can be found on the ISO website.

Introduction

This document defines the requirements of extruded thermoplastic tubing/hoses for non-fuel

applications for automotive use. In addition, it can also be applied as a classification system to enable

original equipment manufacturers (OEMs) to detail a “line call-out” of tests for specific applications

where these are not covered by the four main types (see example in Annex A). In this case, the tubing or

hose would not carry any marking showing this document, but may detail the OEM’s own identification

markings as shown on their part drawings.

DRAFT INTERNATIONAL STANDARD ISO/DIS 13775-1:2021(E)
Thermoplastic tubing and hoses for automotive use —
Part 1:
Non-fuel applications
1 Scope

This document specifies the test requirements and the test methods for extruded thermoplastic tubing

and hoses for use in vehicles powered by internal-combustion engines, excluding use in air braking

systems (see ISO 7628), fuel lines (see ISO 13775-2), and high-pressure hydraulic systems. This

document is intended especially for use by original equipment manufacturers (OEMs).

WARNING — Persons using this document should be familiar with normal laboratory practice.

This document 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 regulatory conditions.

3 Terms and definitions

For the purposes of this document, the terms and definitions given in ISO 8330 apply.

ISO and IEC maintain terminological databases for use in standardization at the following addresses:

— IEC Electropedia: available at http:// www .electropedia .org/
4 Classification and materials

The product shall consist of an extruded thermoplastic material with or without an integral

reinforcement. The product may also have an inner veneer to impart improved fluid resistance and/or

heat resistance. It may also have an extruded outer cover to improve environmental resistance and/or

flame resistance. The outer cover is not necessarily bonded to the tubing or hose.

Four types of tubing and hose for specific applications are specified as follows:

— Type 1: Tubing or hose for vacuum and electronic control;
— Type 2: Tubing or hose for coolant systems;
— Type 3: Tubing or hose for screen/headlamp wash systems;
— Type 4: Tubing or hose for exhaust gas recirculation systems.
5 Dimensions
Diameters and wall thicknesses shall be as given in Table 1.

The wall thickness shall be the sum of the individual thicknesses of the various elements in the

construction of the tubing or hose. The thickness of each individual element shall be such that it is able

to carry out its own function and the total function of the tubing or hose.
