Mining – Air quality control systems for operator enclosures — Performance requirements and test methods
Standard identically adopts ISO 23875:2021 (+ Amd 1:2022) which specifies performance and design requirements for air quality control systems for operator enclosures and their monitoring devices. The design specifications are universal in their application and do not contemplate specific mining environments. They are intended to meet identified parameters of both pressurization and respirable particulate and carbon dioxide concentrations.
