7、nd is identical with ISO 1437:1992 Rubber compounding ingredients Carbon black Determination of sieve residue, published by the International Organization for Standardization (ISO). This standard is a revision of BS 5293-6:1988 which is withdrawn. Cross-reference The Technical Committee has reviewed
8、 the provisions of ISO 565:1990, to which normative reference is made in the text, and has decided that they are acceptable for use in conjunction with this standard. A related British Standard to ISO 565 is BS 410:1986 Specification for test sieves. A British Standard does not purport to include al
9、l the necessary provisions of a contract. Users of British Standards are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations. Summary of pages This document comprises a front cover, an inside front cover, pages i and
10、 ii, pages 1 and 2, an inside back cover and a back cover. This standard has been updated (see copyright date) and may have had amendments incorporated. This will be indicated in the amendment table on the inside front cover. Licensed Copy: sheffieldun sheffieldun, na, Mon Dec 04 16:03:29 GMT+00:00
11、2006, Uncontrolled Copy, (c) BSI BS 5293-6:1992 BSI 08-19991 1 Scope This International Standard specifies a method for determining the water-wash sieve residue from regular, untreated carbon black for the rubber industry. It may not be applicable to oil-treated blacks because the oil could prevent
12、proper wetting of the black by water. 2 Normative reference The following standard contains provisions which, through reference in this text, constitute provisions of this International Standard. At the time of publication, the edition indicated was valid. All standards are subject to revision, and
13、parties to agreements based on this International Standard are encouraged to investigate the possibility of applying the most recent edition of the standard indicated below. Members of IEC and ISO maintain registers of currently valid International Standards. ISO 565:1990, Test sieves Metal wire clo
14、th, perforated metal plate and electroformed sheet Nominal sizes of openings. 3 Principle A known mass of carbon black is washed through a test sieve by a controlled flow of water, and the residue dried and weighed. The test sieve aperture is chosen from the range given in the appropriate material s
15、pecification. 4 Apparatus 4.1 Sieving apparatus (see Figure 1), comprising the following main items: 4.1.1 Test sieve, on which the residue is retained. Test sieves shall be of phosphor bronze or stainless steel, having the characteristics described in ISO 565, and shall have nominal apertures of 50
16、0 4m, 125 4m and 45 4m. 4.1.2 Funnel or container, into the bottom of which the test sieve fits. 4.1.3 Nozzle, fed with clean water under controlled pressure by which the carbon black is washed through the sieve. 4.1.4 Water pressure regulating device Figure 1 Schematic diagram of apparatus Licensed

The pipework downstream of the filter shall not be liable to
18、 corrosion by tap water (use copper or stainless steel, for example). NOTE 1Suitable apparatus includes the Gallie-Porrit type of apparatus and that recommended in ASTM D 1514-88, Test method for carbon black Sieve residue.
