ISO 09044:2016 pdf download.Industrial woven wire cloth — Technical requirements and tests
1 Scope
This International Standard defines terms regarding industrial woven wire cloth for screening purposes and specifies maximum permissible error, requirements, and test methods. It applies to industrial woven wire cloth with square apertures, made of steel, stainless steel, or non- ferrous metals (see ISO 4783-2). It does not apply to woven wire cloth coated after weaving nor does it apply to pre-crimped and welded wire screens which are covered in ISO 4783-3 and ISO 14315. It is of limited application to woven wire cloth used for purposes other than screening which may necessitate other requirements. The alternative requirements may be agreed between the purchaser and the supplier at the time of placing the order.

4 Requirements
4.1 Aperture width and wire diameter combination
Unless otherwise agreed between the supplier and the purchaser, the aperture width and wire diameter combination shall be selected from ISO 2194, ISO 4782, ISO 4783-1, or ISO 4783-2, as appropriate.
4.2 Maximum permissible errors on aperture width
The maximum permissible errors on aperture width are given in Table 1.
In Table 1 and Formulae (1) to (7), the suffix “i”, used with the symbols denotes “industrial wire cloth”.
In Formulae (1) to (8), X i , Y i , s 0 , and w are expressed in micrometres.
NOTE Nominal apertures in Table 1 lower than 1 mm are in µm, higher or equal in mm.
