XB/T 607-2011 (English Version) PDF

Scope: This standard specifies the semi-quantitative determination method of lanthanum, cerium, zirconium, barium and aluminum content in gasoline vehicle exhaust purification catalyst coating materials, as well as the determination method of particle size, shedding rate, thickness, specific surface area and porosity. This standard is applicable to the semi-quantitative determination of lanthanum, cerium, zirconium, barium and aluminum content in gasoline vehicle exhaust purification catalyst coating materials, as well as the determination of particle size, shedding rate, thickness, specific surface area and porosity. The measurement range is particle size 1μm~100μm; shedding rate 0.05%~20%; thickness 0.05mm~1.00mm; specific surface area greater than 1m²/g; porosity 1%~100%.
