prEN 17633

This document specifies the quality testing of e-liquids for vaping products in their fully produced form (“finished e-liquid”), whether containing nicotine or not. It is also applicable to testing of e-liquids when extracted from prefilled cartridges and similar e-liquid presentations to consumers. This document is intended to be read in conjunction with CEN documents WI 00437001, General principles for manufacturing, filling and holding e-liquids for prefilled containers or products, and WI 00437023, E-liquid Ingredients. 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.
