Respiratory protective devices — Methods of test and test equipment — Part 4: Determination of gas filter capacity and migration, desorption and carbon monoxide dynamic testing

Appareils de protection respiratoire — Méthodes d'essai et équipement d'essai — Partie 4: Détermination de la capacité d'un filtre à gaz et essais de migration, de désorption et dynamique au monoxyde de carbone

A new edition is under development: ISO/CD 16900-4.

Abstract / scope

ISO 16900-4:2011 specifies the test method for determining gas capacity of separate or integral gas and combined filters for respiratory protective systems.

ISO 16900-4:2011 includes the validation test at specified flow rates, a desorption test to access the ability of the filter to retain the adsorbed or absorbed gas, and carbon monoxide dynamic testing.
