ISO/TC 24/SC 8 - Test sieves, sieving and industrial screens

ISO 3310-1:2016 specifies the technical requirements and corresponding test methods for test sieves of metal wire cloth. It applies to test sieves having aperture sizes from 125 mm down to 20 µm, in accordance with ISO 565.

ISO 9044:2016 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.

ISO 3310-2:2013 specifies the technical requirements and corresponding test methods for test sieves of perforated metal plate. It applies to test sieves having round holes, with sizes from 125 mm down to 1 mm, or square holes, with sizes from 125 mm down to 4 mm, in accordance with ISO 565.

Specifies technical requirements and test methods for perforated metal plate used for industrial screening purposes and supplied in flat or coiled form. 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.

Table 1 (millimetre sizes) gives principal sizes (R 10) from 1 to 125, and supplementary sizes: R 20 and R 40 from 1 to 125. Table 2 (micrometre sizes) gives principal sizes (R 10) from 5 to 800, and supplementary sizes: R 20 from 20 to 900, R 40 from 32 to 950. This second edition cancels and replaces the first edition (1972).

Gives terms and definitions in English and French to facilitate understanding of the terminology relating to test sieves and test sieving. This second edition cancels and replaces the first edition (1972).

Applies to metal wire cloth with square openings and perforated plates or sheets with square or circular openings. Tables include principal sizes and supplementary sizes. Sizes of 1 mm and above shall be expressed in millimetres and sizes below 1 mm in micrometres.

Tabulates values which are taken from the general list of combinations given in ISO 4783/1. Applies to aperture sizes from 16 mm to 0.02 mm. The wire cloth shall be designated in the following sequence by a) width of aperture, b) diameter of wire, c) material of wire, d) type of weave.

Tabulates a comprehensive range from which preferred groups of combinations may be chosen. The percentage open area of each combination is stated. The screens shall be designated in the following sequence by a) width of aperture, b) diameter of wire, c) material of wire, d) type of weave or type of crimp.

Describes the main factors affecting test sieving and the results obtained. Specifies general principles to be followed concerning apparatus, procedure and presentation of results. Applies to methods in which test sieves of woven wire cloth or perforated metal plate are used. This edition of ISO 2591-1 cancels and replaces in part ISO 2591:1973.

Describes three patterns using round (circular) and square perforations. The sizes of holes range down to 2 mm for square holes and to 0.5 mm for round holes. Five ratios of pitch to hole are specified which result in nominal open areas ranging from about 60 % to 23 %.

Specifies the diameters and the requirements and also tolerances and testing. Applies to wire with circular cross-section from 25 to 0.02 mm in diameter. The second edition cancels and replaces the first edition (ISO 4782:1981).

Describes three patterns using round (circular) and square perforations in low carbon steel plate of 3 mm thickness and above. The sizes of holes range from 125 to 3.15 mm inclusive. Five ratios of pitch to hole are prescribed which result in nominal open areas ranging from about 64 to 23 %.

The perforation of a plate is designated by 1: shape of the holes, 2. aperture size, 3. mutual arrangement of holes, 4. pitch, 5. orientation of the arrangement of the perforations relative to the edges of the plate. The code expresses the items of designation by symbols and magnitudes in the sequence above. The standard applies to perforated plates regardless of the plate material.

Tabulates values which are taken from the general list of combinations given in ISO 4783/1. Applies to aperture sizes from 125 to 1 mm. The screens shall de designated in the following sequence by a) width of aperture, b) diameter of wire, c) material of wire, d) type.
