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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3.
Draft International Standards adopted by the technical committees are circulated to the member bodies for voting.
Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this part of ISO 13775 may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights.
International Standard ISO 13775-1 was prepared by Technical Committee ISO/TC 45, Rubber and rubber
products, Subcommittee SC 1, Hoses (rubber and plastics).
ISO 13775 consists of the following parts, under the general title Thermoplastic tubing and hoses for automotive
use:
� Part 1: Non-fuel applications
� Part 2: Petroleum-based-fuel applications
Annexes A and B of this part of ISO 13775 are for information only.

Introduction
This specification defines the requirements of extruded thermoplastic tubing/hoses for non-fuel applications for
automotive use. In addition, it may 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 ISO specification number, but may detail the OEM’s own identification markings as shown on their part
drawings.
INTERNATIONAL STANDARD ISO 13775-1:2000(E)
Thermoplastic tubing and hoses for automotive use —
Part 1:
Non-fuel applications
WARNING — Persons using this part of ISO 13775 should be familiar with normal laboratory practice. This
part of ISO 13775 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 part of ISO 13775 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 7628-2), fuel lines (see ISO 13775-2) and high-pressure hydraulic systems. This specification is intended
especially for use by original equipment manufacturers (OEMs).
2 Normative references

3 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 h
