16、odification. BS EN ISO 8130-1:2010 BSI 2011 11 ScopeThis part of ISO8130specifies a method for the determination of particle size distribution by sieving. It discriminates between particles in the size range from324m to3004m.The method can also be used as an abbreviated procedure, i.e. for the deter

17、mination of the residue on one single sieve only (“go”/“no go” test).2 Normative referencesThe following standards contain provisions which, through reference in this text, constitute provisions of this part of ISO8130. At the time of publication, the editions indicated were valid. All standards are

18、subject to revision, and parties to agreements based on this part of ISO8130are encouraged to investigate the possibility of applying the most recent editions of the standards indicated below. Members of IEC and ISO maintain registers of currently valid International Standards.ISO 565:1990, Test sie

The frame and the mesh of the test sieves shall be of met

20、al. The range of nominal mesh apertures shall be between324m and3004m and shall comply with the requirements of ISO565for supplementary sizes (see Annex A). The test sieve shall be covered with a transparent lid.The choice of mesh apertures (see Annex A) will depend on the circumstances. If the appr

21、oximate particle size distribution of a sample is known, it is necessary to use only those test sieves that are appropriate to that particle size range. It is also permissible to restrict the choice of test sieves to those that give sufficient data for a specific purpose. Appropriate details shall b

In the base of the casing shall be an outlet (to which an extractor fan is connected), and an air inlet to permit the injection of air.The air

23、 inlet is connected to a jet rotating at20r/min to25r/min and consisting of a slot-shaped nozzle arranged radially beneath and very close to the sieve mesh. When the jet rotates, it blows air continuously through the mesh, preventing the coating powder particles from blocking the test sieve. The air

24、 is extracted through the outlet, drawing the finer particles through the sieve.The flow of air is controlled by adjusting a slot at the outlet.3.3 Timer (e.g. stopwatch), recording to the nearest1s or better. It may be with a switch fordisconnecting the motor from the sieve apparatus (3.2).3.4 Bala

26、 described in ISO842.5 Preparation of the test sieves5.1 Using the magnifying glass (3.6), check that the test sieve is clean and undamaged and is not blocked by material used in a previous determination.5.2 If it is necessary to clean the test sieve, clean it using the ultrasonic system (3.7).6 Pro

27、cedureCarry out the determination in duplicate.6.1 Weigh, to the nearest0,01g, the test sieve (3.1) with its transparent lid.6.2 Weigh, to the nearest0,01g, a20g test portion of the sample, except when using a test sieve of mesh aperture less than904m where a10g test portion is taken.6.3 Secure the

28、selected test sieve in position in the sieve apparatus (3.2) and transfer the test portion to the test sieve. Secure the transparent lid, reduce the pressure in the apparatus by (2 0,3) kPa1) and initiate the rotation of the nozzle. Unless otherwise specified, operate the apparatus for (300 15) s.1)

If any ma

30、terial becomes attached to the frame and/or the transparent lid, lightly tap either or both with the mallet (3.5) to dislodge the attached powder.NOTE 1Difficulties may be experienced in sieving extremely fine materials. The addition of a suitable, extremely fine sieving aid (pyrogenic silica or pyr

31、ogenic alumina may be suitable) to the sample at the level of0,2%(based on the initial mass of the test portion) should aid the process. No correction is required for the mass of this additional material as it will pass through the sieve.6.4 At the end of the test period, allow the air pressure to s

32、lowly equalize with that of the room. Remove the lid and the test sieve together with the retained material and weigh to the nearest0,01g.6.5 To determine the particle size distribution by mass determine the mass retained on the test sieve of the smallest aperture chosen as described in the introduc

33、tion. Repeat the procedure described in6.1 to6.4 using a fresh test portion for each size of test sieve, in ascending order, in the range (see3.1) to be reported.NOTEThis diagram illustrates the functioning of the apparatus and is schematic only.Figure 1 Air-jet sieve apparatusBS EN ISO 8130-1:2010E
