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 ).

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;
• 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.

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.
