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 have been updated (Clause 2);
— Clause 3 has been added.
A list of all parts in the ISO 13775 series can be found on the ISO website.
Any feedback or questions on this document should be directed to the user’s national standards body. A

Introduction
This document defines the requirements for extruded thermoplastic tubing/hoses for non-fuel
applications for automotive use. In addition, it can 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 referring to this document but may detail the OEM’s own identification markings
as shown on their part drawings.

Non-fuel applications
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.
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).

3 Terms and definitions
For the purposes of this document, the terms and definitions given in ISO 8330 apply.
ISO and IEC maintain terminology databases for use in standardization at the following addresses:
— ISO Online browsing platform: available at https:// www .iso .org/ obp
— IEC Electropedia: available at https:// 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.

6 Requirements
The following tests shall be selected for each application of the tubing or hose based on the performance
requirements of the finished product. All tests shall be carried out without the unbonded protective
cover.
a) Burst pressure: When determined in accordance with ISO 1402, the minimum burst pressure for
all constructions shall be 2 MPa gauge (20 bar).
b) Proof pressure: When determined in accordance with ISO 1402, the proof pressure for all
constructions shall be 1 MPa gauge (10 bar).
c) Cold impact resistance: After cold impact testing at −40 °C in accordance with ISO 7628:2010, 9.3,
all constructions shall show no evidence of external fracture or cracking and shall meet the burst
