Thermoplastic tubing and hoses for automotive use — Part 1: Non-fuel applications

ISO 13775-1:2015 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 part of ISO 13775 is intended especially for use by original equipment manufacturers (OEMs).

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 second edition cancels and replaces the first edition (ISO 13775-1:2000), which has been
technically revised.
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
Annex A, Annex B, and Annex F of this part of ISO 13775 are for information only.

Introduction
This part of ISO 13775 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 part of ISO 13775, but may detail the OEM’s own
identification markings as shown on their part drawings.

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 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.
4 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.

5 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).
