Test method for assessing the performance of gas-phase air cleaning media and devices for general ventilation - Gas-phase air cleaning media Ingestion-build-78747 Land pollution1 Scope This part of ISO 10121 aims to provide an objective laboratory test method, a suggested apparatus, normative test sections and normative tests for evaluation of three different solid gas phase air cleaning media (GPACM) or GPACM configurations for use in gas phase air cleaning devices intended for general filtration applications. This part of ISO 10121 is specifically intended for challenge testing and not for general material evaluation or
