Use of any
33、 other particle size analysis equipment will obtain different results. Other particle size analysis instruments may be acceptable for analysis of test dust products specified in ISO 12103-1, if suitability and correlation is determined between the Microtrac S3500TMand the other analyser. Use of part
34、icle size analysis instruments other than the Microtrac S3500TMwill require a modified particle size analysis procedure.The Microtrac Model S3500TMemploys use of three light scattering lasers that are combined to produce the resulting particle size distribution data. A tri-laser system uses precise
35、angular measurement of scattered light through a full 180 angular range with three lasers and two detector arrays. Analysis of scattered light to determine particle size employs a Mie based unified angular scattering theory with a dynamic range of 0,02 microns to 2 800 microns (see Table A.1).Normal
36、ly, it is not acceptable to publish a manufacturers name or equipment identification. However, due to the close tolerance of the specified particle size limits and variation between instruments by multiple manufacturers, one particle size analysis instrument was defined for this specification.Partic
37、le size distribution specified limits shown in Table 2 were derived from sample analysis of PTI manufactured test dust produced prior to May 1994 using three separate Microtrac Model S3500TMlight scattering analysers.Table A.1 Microtrac Model S3500TMspecificationsItem SpecificationMeasuring range 0,

43、tain a clean vial and add the required representative sample quantity based on Table A.2.Table A.2 Microtrac S3500TMSample WeightsISO grade Sample amount in mgISO ultrafine 14-16ISO fine 29-31ISO medium 39-41ISO coarse 54-56c) Add one drop of dispersant to the vial. It is very important that dispers
44、ant used does not create bubbles.d) Add approximately 10 ml distilled water to the vial and mix by gently moving the vial in a circular motion. Avoid creating bubbles.e) Place sample vial and contents in an external low power ultrasonic bath, having a water depth of 2 cm, for 30 s. The ultrasonic ba
45、th should be in the range of 50 W to 100 W, 50 kHz to 80 kHz.
