Scope This Japanese Industrial Standard specifies both: the test powders(1) which can be used for the dust separation

9、 test of a dust sepa- rator or an air filter, for the function test of various testers, and for wear test; and the test particles(2) which can be used for the calibration of light-scattering automatic particle counter, the test of particle collecting rate for super high performance air filter, and t

10、he calibration of an automatic counter of particulate materials floating in air. Notes ( 1 Test powders Powders are classified into test powders 1 and test powers 2, and powders 1 is for the separation test of a dust separator or air filter, for the function test of various testers, has a constant c

Test powders 2 is for the verification of apparatus relating to powder and for the operating function test and the wear test of various testers against powders, has a constant characteristics, and has typical characteristics of gener

(2) Test particles Test particles are classified into test particles 1 and test particles 2, and test particles 1 is polystyrene group particles. of styrene, and is monodispersed system which has the same sized solid particles and synthesized by emulsion polymeri- zation. Usually, they ar

Otherwise, they are sprayed or mixed with dry air to evaporate water, and prepared for fine particles for test. Particles 1 mainly consists Test particles 2 is fine particles
