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 pm-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.
