Scope

This standard specifies the semi-quantitative determination methods for the contents of lanthanum, cerium, zirconium, barium, and aluminum in the coating materials of exhaust gas purification catalysts for gasoline vehicles, as well as the determination methods for their particle size, shedding rate, thickness, specific surface area, and porosity.
This standard applies to the semi-quantitative determination of the contents of lanthanum, cerium, zirconium, barium, and aluminum in the coating materials of exhaust gas purification catalysts for gasoline vehicles, as well as the determination of their particle size, shedding rate, thickness, specific surface area, and porosity. The measurement range is particle size of 1 μm to 100 μm; shedding rate of 0.05% to 20%; thickness of 0.05 mm to 1.00 mm; specific surface area greater than 1 m2/g; and porosity of 1% to 100%.
