JIS Z 8901 Class 17 Calcium Carbonate Heavy

About JIS Z 8901 Class 17 Calcium Carbonate Heavy

JIS Z 8901 Class 17 Heavy Calcium Carbonate is a standardized test powder formulated in accordance with the Japanese Industrial Standard Z 8901, Class 17. This material is used for testing and calibration of filtration systems, air cleaning devices, and particle handling equipment, particularly where high-density, inorganic particle simulation is required.

This grade consists primarily of finely milled heavy calcium carbonate (CaCO) with controlled particle size distribution and high chemical purity. It is chemically stable, non-reactive, and ideal for both dry and wet testing procedures.

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.

Superior Purity and Quality

With a remarkable 99% purity level, our Calcium Carbonate Heavy complies with JIS Z 8901 Class 17 standards. Its exceptional quality ensures precise outcomes in laboratory experiments and industrial testing, offering consistent results across a range of scientific and technical applications.


Optimal Storage and Stability

Benefit from extended shelf life thanks to stable performance under dry, sealed storage. Keeping the product away from moisture and contaminants maintains its high purity and effectiveness, ensuring reliable results when needed for both research and industrial use.
