6、-2 : 1989 Industrial wire screens and woven wire cloth - Guide to the choice of aperture size and wire diameter combinations Part 2: Preferred combinations for woven wire cloth Foreword IS0 (the International Organization for Standardization) is a worldwide federation of national standards bodies (I

7、S0 member bodies). The work of preparing International Standards is normally carried out through IS0 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, gov

8、ern- mental and non-governmental, in liaison with ISO, also take part in the work. IS0 collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. Draft International Standards adopted by the technical committees are circulated to

9、 the member bodies for approval before their acceptance as International Standards by the IS0 Council. They are approved in accordance with IS0 procedures requiring at least 75 % approval by the member bodies voting. International Standard IS0 4783-2 was prepared by Technical Committee ISO/TC 24, Si

10、eves, sieving and other sizing methods. This second edition cancels and replaces the first edition (IS0 4783-2 : 19811, of which it constitutes a minor revision. IS0 4783 consists of the following parts, under the general title Industrial wire screens and woven wire cloth - Guide to the choice of ap

11、erture size and wire diameter combi- nations : - Part 1 : Generalities - Part 2: Preferred combinations for woven wire cloth - Part 3: Preferred cornbinations for pre-crimped or pressure-welded wire screens 1 Scope This part of IS0 4783 tabulates preferred combinations of aper- ture size and wire di

12、ameter for industrial woven wire cloth which are taken from the general list of aperturelwire combi- nations given in IS0 4783-1. It applies to woven wire cloth of aperture size from 16 mm to 0.02 mm. NOTE - This is the first International Standard on woven wire cloth for industrial purposes; these

13、specifications are a compromise which takes account of existing national standards. IC0 Member Bodies are earnestly requested to rationalize further in order to reduce the number of wire diameters per aperture width within the next five years without excluding the option of increasing the number of

14、preferred apertures. IS0 4783-3 gives the preferred combinations for pre-crimped or pressure-welded wire screens. 2 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this part of IS0 4783. At the time of publication, the e

All standards are subject to revision, and parties to agreements based on this part of IS0 4783 are encouraged to investigate the possibility of applying the most recent editions of the standards listed below.
