Test methods for assessing the performance of gas-phase air cleaning media and devices for general ventilation - Part 2: Gas-phase air cleaning devices (GPACD) (ISO 10121-2:2013)

This technical specification establishes the methodological framework for evaluating general ventilation materials and equipment specifically designed for gas phase purification. As the second installment in a series, it focuses exclusively on the assessment of Gas Phase Adsorption Canisters for Device, commonly referred to as GPACD. The document outlines standardized procedures to ensure consistent and reliable testing of such devices under various conditions. It provides detailed guidance on the selection of test gases, the configuration of ventilation systems, and the calculation of performance metrics. By adhering to this framework, manufacturers and laboratories can assess the efficiency and operational stability of purification units intended for respiratory protection and environmental control. The approach ensures that evaluation results are comparable across different testing environments and facilitate the verification of device capabilities against established safety and performance benchmarks without requiring specific institutional approval references.
