BS EN ISO 23875:2022 PDF

Scope: 1 Scope This document 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. This document also specifies test methods to assess such parameters and provides operational and maintenance instructions. Recommendations are made for operational integration of the air quality control system . Gases and vapours that can be a hazard in the work environment outside of the operator enclosure are excluded from this document.
