24、 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
25、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. International Standards are drafted in acc
26、ordance with the rules given in the ISO/IEC Directives, Part 3. 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. Attention
27、 is drawn to the possibility that some of the elements of this International Standard may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. International Standard ISO 4610 was prepared by Technical Committee ISO/TC 61, Plastics, Subcomm
28、ittee SC 9, Thermoplastic materials. This second edition cancels and replaces the first edition (ISO 4610:1977), which has been modified as follows: emulsion-polymerized PVC has been included in the scope; a second obligatory measurement has been included; a precision statement, based on current tes
29、t data, has been included.

30、ieve retention and particle size distribution of preferably free-flowing vinyl chloride homopolymer and copolymer resins prepared by the “suspension”, “bulk” and “emulsion” polymerization processes. Control of these characteristics can help to ensure consistency of supply and predictable processing

For dated references, subsequent amendments to, or revisions of, any of these publications do not apply. However, parties
32、 to agreements based on this International Standard are encouraged to investigate the possibility of applying the most recent edition of the normative document indicated below. For undated references, the latest edition of the normative document referred to applies. Members of ISO and IEC maintain r

Generally, shall be used for each sieve analysis. For fine-particle resins,
35、 which for the purpose of this International Standard are defined as between and , smaller quantities are more convenient, for example . 5 Sample preparation Unless otherwise agreed, analyse the sample as received (i.e. as delivered). If the sample is not analysed on the day of receipt, it shall be
36、kept in a sealed container under ambient conditions. To prevent difficulty in sieving caused by electrostatic charging of the resin, add an antistatic agent, for example by mass of -alumina, unless otherwise specified, to the resin at the start of the analysis. 25 g 80 m 100 m 10 g 0,5 % ENISO4610:2

The choice of mesh aperture depends on the requirements and the particle size distribution of the resin to
38、 be examined. NOTE A suitable method of cleaning sieves is to use an ultrasonic cleaning device containing water and a detergent. 6.2 Air-jet sieve apparatus (see Figure 1), consisting of a casing designed to contain a sieve (6.1), in the lower part of which are an outlet, to which suction may be ap
39、plied, and an air inlet. The casing shall be covered with a preferably transparent lid.

40、2 All rithgs rreseved 3 The air inlet shall be fitted with a rotating jet consisting of a slot-shaped nozzle arranged radially beneath and very close to the sieve, so that when in rotation it blows air continuously through the sieve to keep the particles suspended. The exhaust air pulls the finer pa
41、rticles through the sieve. The flow of air can be controlled by adjusting the working pressure, measured at the outlet; this may be achieved by means of an adjustable slot on the vacuum attachment.

43、(see 6.1) into the sieve apparatus (6.2). Weigh, to the nearest , the material to be sieved, transfer it onto the sieve, and place the cover on the sieve apparatus. Regulate the flow of air to give a partial vacuum of (for example by means of the adjustable slot on the vacuum attachment see 6.2). Op
44、erate the motors of the sieve apparatus and the vacuum device for for each sieving test. If during the sieving process a deposit becomes visible under the lid, sieving shall be interrupted and the deposit brushed down onto the sieve. The accuracy and precision of the method are not as good when the
45、screen residue is small (less than , for example). In such cases it is of interest to extend the sieving time (to or even ). However, for referee (in particular for designation) purposes, the value obtained after shall be used. After switching off the motors, weigh the residue on the sieve to the ne
46、arest (for example by weighing the sieve and its contents and subtracting the tare). Repeat the procedure, as necessary, with sieves of different mesh aperture. 8 Expression of results Calculate the sieve retention , as a percentage, from the equation where is the mass, in grams, of sample used for
