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 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.
This fourth edition cancels and replaces the third edition (ISO 8028:2017), which has been technically
revised.
The main changes compared to the previous edition are as follows:
— Clause 8.1 and Table A.2 has been re-written to clarify the conditions for the number of test samples.
— Clause 8.2 has been re-written to make it appropriate minimum bend radius and requirements.
— In Clause 13, year of publication has been deleted and change the unit of working pressure to MPa
as a main unit.
— Update the Normative References.
Any feedback or questions on this document should be directed to the user’s national standards body. A
complete listing of these bodies can be found at www.iso.org/members.html.

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.
2 Normative references

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 200 bar (20 MPa), intended for
spraying paints containing solvents at temperatures from –20 °C to +50 °C.
— Type B: Assemblies designed for a maximum working pressure of 360 bar (36 MPa), intended for
spraying paints containing solvents at temperatures from –20 °C to +50 °C.
— Type C: Assemblies designed for a maximum working pressure of 2
