The current version of the standard addresses filtering respirators for particulate matter only.  It is anticipated that future work will create content for Canadian respirator performance standards covering gas/vapour filtering respirators, atmosphere-supplying respirators and Chemical-Biological-Radiological-Nuclear protective respirators.  For this reason, there are clauses in the document reserved for future use.

This document solely covers product performance:  requirements for the respirator certification process, manufacturer quality control/documentation and auditing are described in separate documents.  Respirator selection, use and care is covered by CSA Z94.4.
