ČSN P CEN/TS 17633

This document specifies the manufacturing quality testing of e-liquids for vaping products in their fully produced form, i.e. "finished e-liquid", at the point of manufacture, whether containing nicotine or not. This document is intended to be read in conjunction with EN 17647 and EN 17648. NOTE - Testing for undesirable constituents is outside the scope of this document because their presence in final e-liquid is limited by controls at the ingredient level. The maximum level of undesirable constituents is set in the ingredient specification and monitored by testing at a frequency determined appropriate by the manufacturer.
