ISO 9044 pdf download.Industrial woven wire cloth — Technical requirements and testing 1 Scope This International Standard defines terms regarding industrial woven wire cloth for screening purposes and specifies tolerances, 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 1 431 5. 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. 2 Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of this International Standard.
