T/CRAAS 438.2-2020 Performance test method for air purification materials and devices used for general ventilation pollutants in gaseous form - Part 2: Air purification devices (GPACD)

Scope

Main technical content: T/CRAA 438.2-2020 specifies a set of performance testing methods for gaseous pollutant air purification devices. The determination of the performance of purification materials is described in T/CRAA 438.1-2020. This standard aims to provide an objective testing method to evaluate the performance of full-scale gaseous pollutant air purification devices (GPACD) used in general filtration, regardless of the materials or technologies used. One of the objectives of this standard is to avoid confusing device test data with material parameters. The advantage of this approach is that purification device customers can focus solely on product price and performance, while suppliers can adopt objective standard testing methods without disclosing product confidential information or manufacturing techniques. This standard does not favor any specific supplier of testing equipment and does not provide specific design requirements for testing equipment. It only stipulates effective performance testing. The standard cites various design examples currently in use. As long as it is used for general ventilation, whether for civilian or non-civilian purposes, and can be installed on a test bench, this standard can also be used for testing devices such as scrubbers, absorbers, non-adsorption equipment, and packed towers, and provides effective evaluation. This standard does not apply to nuclear energy and military applications.
