GB/T 45504-2025 Nanotechnologies—Nanostructured porous alumina as catalyst support for vehicle exhaust emission control—Characteristics and measurement methods
Abstract
This document specifies the measurement characteristics of nano-structured porous alumina powders used as catalyst carriers for automotive exhaust emission control, and describes the corresponding measurement methods. Based on agreements between the relevant parties, this document includes the key characteristics that need to be measured and additional characteristics recommended for measurement, and recommends measurement methods for each characteristic.
This document is applicable to the measurement of the nano-structured porous alumina characteristics of gasoline-powered vehicles, and is not applicable to the characterization of characteristics related to health, environmental, and safety issues.
