ISO 10630:1994(en) Industrial plate screens — Specifications and test methods
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.
Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.
International Standard ISO 10630 was prepared by Technical Committee ISO/TC 24, Sieves, sieving and other sizing methods, Subcommittee SC 7, Industrial plate screens.
1 Scope
This International Standard specifies technical requirements and test methods for perforated metal plate used for industrial screening purposes and supplied in flat or coiled form.
It applies to perforated plates of low carbon steel according to ISO 7805-1 and ISO 7805-2 with nominal sizes of holes from 1 mm for round holes and 4 mm for square holes up to 125 mm according to ISO 2194, and with a maximum plate thickness of 12,5 mm.
2 Normative references
The following standards contain provisions which, through reference in this text, constitute provisions of this International Standard. At the time of publication, the editions indicated were valid. All standards are subject to revision, and parties to agreements based on this International Standard are encouraged to investigate the possibility of applying the most recent editions of the standards indicated below. Members of IEC and ISO maintain registers of currently valid International Standards.

3 Definitions
For the purposes of this International Standard, the following definitions apply.
3.1
plate
Flat rolled material for the manufacture of perforated metal plate, 3 mm to 12,5 mm thick, the edges of which are allowed to deform freely during rolling, supplied in flat form and generally in rectangular shape, but also in any other shape according to a design sketch.1) 3.2
sheet
Flat rolled material for the manufacture of perforated metal plate, less than 3 mm thick, the edges of which are allowed to deform freely during rolling, supplied in flat form and generally in rectangular shape, but also in any other shape according to a design sketch.1) 3.3
coil
Flat rolled sheet for the manufacture of perforated metal plate, the edges of which are allowed to deform freely during rolling and which immediately after the final rolling pass is wound into regular superimposed laps.
3.4
perforated plate
Screening surface consisting of a plate with uniform holes in symmetrical arrangement. The holes may be square, slotted, circular or of other regular geometrical shape.
3.5
plate thickness
Thickness of the plate before perforation.
3.6
feed direction
Direction in which a plate or sheet was fed through the perforating press.
3.7
punch side
Surface of a perforated plate which the punch entered.
3.8
hole size
Diameter of a round hole or distance between opposite sides of a square hole of a perforated metal plate.
3.9
pitch
Distance between corresponding points of two adjacent holes in a perforated plate.
3.10
bridge width
bar
Distance between the nearest edges of two adjacent holes in a perforated plate.
3.11
margin
Distance between the outside edges of the outside rows of holes and the edges of a perforated plate.
3.12
percentage open area
Ratio, expressed as a percentage, of the total area of the holes to the total area of the perforated part of the plate (excluding any non-perforated parts).
3.13
roller levelling
Cold mechanical operation on a perforated metal plate to promote flattening.
