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 document 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).
ISO draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed patent rights
in respect thereof. As of the date of publication of this document, ISO had not received notice of (a) patent(s)
which may be required to implement this document. However, implementers are cautioned that this may not
represent the latest information, which may be obtained from the patent database available at
www.iso.org/patents.www.iso.org/patents. ISO shall not be held responsible for identifying any or all such
patent rights.
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.

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

This document was prepared by Technical Committee ISO/TC 45, Rubber and rubber products, Subcommittee
SC 1, Rubber and plastics hoses and hose assemblies, in collaboration with the European Committee for
Standardization (CEN) Technical Committee CEN/TC 218, Rubber and plastics hoses and hose assemblies, in
accordance with the Agreement on technical cooperation between ISO and CEN (Vienna Agreement).
This fourth edition cancels and replaces the third edition (ISO 8028:2017), which has been technically revised.
The main changes are as follows:
— — subclause 8.1subclause 8.1 and Table A.2 has(merged with Table A.1) have been re-written to clarify
the conditions for the number of test samples;
— — subclause 8.2subclause 8.2 has been re-written to make appropriate minimum bend radius and to
confirm the Electrical-continuity requirements after the impulse test;
— — subclause 8.3subclause 8.3 has been re-written to citatecite appropriate subclauses in ISO 8031;
—
— — in Clause 12,Clause 12, year of publication has been deleted, and change the unit of working pressure
to MPa as a main unit has been changed;

FINAL DRAFT INTERNATIONAL STANDARD ISO/FDIS 8028:2024(E)

Rubber and/or plastics hoses and hose assemblies for airless paint
spraying — Specification
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 safety and health practices.
1 Scope
This document specifies the requirements for four types of hose and hose assemblies for use in airless paint
spraying. The four types are differentiated by burst pressure and operating temperature, and can be
constructed from rubber or plastic materials, or a combination of rubber and plastic material.

4 Types of hose and hose assemblies
Four types of hose and hose assemblies are specified, as follows:
— — Type A: Assemblies designed for a maximum working pressure of 20 MPa (200 bar), intended for
spraying paints containing solvents at temperatures from –20 °C to +50 °C;
— — Type B: Assemblies designed for a maximum working pressure of 36 MPa (360 bar), intended for
spraying paints containing solvents at temperatures from –20 °C to +50 °C;
— — Type C
