Foreword

ISO (the International Organization for Standardization) is a worldwide federation of national standards institutes (ISO member bodies). The work of developing International Standards is carried out through ISO technical committees. Every member body interested in a subject for which a technical committee has been set up 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.

Draft International Standards adopted by the technical committees are circulated to the member bodies for approval before their acceptance as International Standards by the ISO Council.

International Standard ISO 4783/3 was developed by Technical Committee ISO/TC 24, Sieves, sieving and other sizing methods, and was circulated to the member bodies in December 1979.

It has been approved by the member bodies of the following countries :

Canada Ireland Spain

Egypt, Arab Rep. of Netherlands Switzerland

France Portugal United Kingdom

Germany, F.R. Romania USA

India South Africa, Rep. of USSR

No member body expressed disapproval of the document.\

1   Scope and field of application

This part of ISO 4783 tabulates preferred combinations of aperture size and wire diameter for pre-crimped or pressure welded wire screens for industrial purposes which are taken from the general list of aperture/wire combinations given in ISO 4783/1.

It applies to wire screens of aperture size from 125 to 1 mm.

NOTE — This is the first International Standard on pre-crimped or pressure welded wire screens for industrial purposes; these specifications are a compromise which takes account of existing national standards. ISO Member Bodies are earnestly requested to rationalize further in order to reduce the number of wire diameters per aperture width within the next 5 years without excluding the option of increasing the numbers of preferred apertures.

Part 2 of this International Standard gives the preferred combinations for woven-wire cloth.
