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. 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.
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, 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 8.1 and Table A.2 (merged with Table A.1) have been re-written to clarify the conditions for the
number of test samples;
— subclause 8.2 has been re-written to make appropriate minimum bend radius and to confirm the
Electrical-continuity requirements after the impulse test;
— subclause 8.3 has been re-written to cite appropriate subclauses in ISO 8031;
— in Clause 12, year of publication has been deleted, and the unit of working pressure to MPa as a main unit
has been changed;
— Annex B has been deleted;
— the Normative references have been updated.
Any feedback or questions on this document should be directed to the user’s national standards body. A

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.
