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.

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 water, weak aqueous chemical solutions and abrasive solids and slurries.
If there is a special requirement for resistance to deleterious chemicals, this is a matter for agreement
between the supplier and the purchaser.

thermoplastics hoses for suction and discharge of aqueous
materials — Specification
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 health and
safety practices and to ensure compliance with any national regulatory conditions.
1 Scope
This International Standard specifies the requirements for three types of helical-thermoplastic-
reinforced thermoplastics hoses for suction and discharge of water, weak aqueous chemical solutions
and abrasive solids and slurries, for use in the ambient temperature range from −10 °C to 55 °C.
The three types of hose are for light-, medium- and heavy-duty applications.
The types of hoses covered in this International Standard are not intended for use with flammable or
combustible materials, nor with aromatic solvents.
NOTE Hoses of a similar construction for suction and discharge for fire-fighting are specified in ISO 14557.
