Remarks Welding fumes (not otherwise classified) 5 SKC 225-8-01-1 or 225-8-04 polyvinyl 1,5 180 Grav 25 4,9 IRSST 48-1 chloride filter 902 PVC filter-37 914 PVC filter-25 For evaluating welding fumes, if personal sampling must be done inside the mask, use an adaptor available from SKC Cat. No. 225-600. If metals must be analyzed, use a preweighed MCE filter (code 916 or 913) Additional information is available in Info-Labo 91-03. The weight measurement method for dusts is by definition non-specific.
