Electronic cigarette testing in the United States includes testing items such as nicotine, propylene glycol, glycerol, nitrosamines, diethylene glycol, phthalates, 2,3-butanedione, total lead, and soluble heavy metals. What does the US e-cigarette certification program include? The electronic cigarette certification projects are as follows:

1、 Normal Test for E-liquid

Propylene Glycol/Vegetable Glycerin

Detection method: Determination of propylene glycol and glycerol in electronic cigarette oil (C-F&C-1420-TP);

1.2. Nicotine

Detection method: Determination of nicotine content in electronic tobacco oil (C-F&C-1419-TPNicotine free);

1.3. Diethylene glycol

Detection method: determination of diethylene glycol content in electronic cigarette oil (C-F&C-1417-TP);

1.4. Nitrosamines

Test method: Phthalate esters in electronic cigarette oil. Determination of nitrosamine content (C-F&C-1418-TP);

1.5. Diacetyl (2,3-butanedione)

Determination of 2,3-butanedione in electronic cigarette oil (C-F&C-1421-TP);

1.6. Phthalates (17m)

Phthalate esters in electronic cigarette oil. Determination of nitrosamine content (C-F&C-1418-TP);

1.7. Heavy metal (As, Pb, Hg, Cr, Ni, Cdetc)

Determination of soluble heavy metal content in electronic tobacco oil (C-F&C-1423-TP).

All testing methods are certified by CNAS.
