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.

This document was prepared by Technical Committee ISO/TC 131, Fluid power systems, Subcommittee SC 5, Control products and components.

This third edition cancels and replaces the second edition (ISO 5782-1:1997), which has been technically revised.

The main changes compared to the previous edition are as follows:

• 4.2.2 has been modified to include common port forms described in Annex A;
• 4.4 has been added for optional filter efficiency and reference to air purity in Annex B;
• Annex A has been added which describes the port forms from ISO 1179:1981;
• Annex B has been added describing codes for air purity from ISO 8573-1 with typical applications.

A list of all parts in the ISO 5782 series can be found on the ISO website.

Introduction

In pneumatic fluid power systems, power is transmitted and controlled through air under pressure within a circuit. Where mechanical filtration of the air media is desired, filters are components designed to remove solid and liquid contaminants from compressed air.

1 Scope

This document specifies which characteristics of compressed air filters are to be included in the supplier's literature.

It also specifies product-marking requirements.

This document is applicable to compressed air filters, constructed from light alloys (aluminium, etc.), zinc diecast alloys, brass, steel and plastic, with a rated pressure of up to 1 600 kPa (16 bar) and a maximum temperature of 80 °C, designed to remove solid and liquid contaminants from compressed air by mechanical means.
