JIS Z 8901 Class 5 Fly Ash

About JIS Z 8901 Class 5 Fly Ash

JIS Z 8901 Class 5 Fly Ash Test Dust is astandardized, lab-grade dust designed to simulate real-world particulatecontamination from combustion processes, especially in power andindustrial sectors. Class 5 represents a coarser version of fly ashdust, with a broader particle size distribution than Class 10, making itsuitable for durability, clogging, and ingress testing in harshenvironments.

Composed mainly of silica, alumina, and iron oxide,this dust is stable, flowable, and compliant with JIS Z 8901 Class 5specifications.

Scope : This Japanese Industrial Standard specifies both: the test powders which can be used for the dust separatio n test of a dust separtation test of a dust separator or an air filter, for the function test of various testers, and for wear test; and the test particles, 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 the calibration of an automatic counter of particulate materials floating in air.
Test Powder Class 4 and Class 9 The quality of test powders class 4 and class 9 (Talc) shall conform to the following items.Particle Density : Particle density shall be the value of 2.7 g/cm3 to 2.9 g/cm3 when measured according to the method in test.
