CEN/TS 17633:2022

This document specifies the manufacturing quality testing of e-liquids for vaping products in their fully produced form "finished e-liquid" at the point of manufacture, whether containing nicotine or not.
This document is intended to be read in conjunction with FprEN 17647 and FprEN 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.
