Coil Configuration and Heater Type (Symbol 2-4)

Full category name: Vaporizer Attributes of Cig-a-likes (CLs), Advanced Personal Vaporizers (APVs), E-Hookahs (EHs) and Herbal Vaporizers (HWOVs) (Group 2)

2.4      Coil Configuration and Heater Type (Symbol 2-4)

There are currently nine numerical options defining coil quantity and location that are assigned to the fifth and last symbol of the Vaporizer group code:

1 – Single Lower Coil for CLs, APVs, EHs, or HDs (Lp)

2 – Multiple Lower Coils for CLs, APVs, EHs or HDs (Lp)

3 – Single Upper Coil for CLs, APVs, EHs or HDs (Lp)

4 – Multiple Upper Coils for CLs, APVs, EHs or HDs (Lp)

5 – Single Inserted Coil for CLs, EHs or HDs (Lp)

6 – Multiple Inserted Coils for CLs, APVs, EHs or HDs (Lp)

7 – Coils absent for CLs, APVs, EHs or HDs (Lp)

(Instead of a classical coil an ultrasonic membrane is used)

8 – Coil and Ultrasonic membrane for APVs, EHs or HDs (Lp)

9 – Mash Coil for APVs, EHs or HDs (Lp)

This symbol is applicable to all the four vaping device classes. 

Numeric options (0 ) are reserved for any future expansions of our classification system.

 

2.4.1     Coil Configuration of CLs, APVs, EHs and HDs (Lp)

Applicability of these options is determined by their tank type coded with symbol 2-1.  For example, options 1 through 4 are applicable to clearomizers and capsules and options 5 and 6 are applicable to built-in tanks, cartomizers and capsular tanks.

1 – Single Lower Coil

This option includes devices with a single coil submerged into the tank liquid.

 

2 – Multiple Lower Coils

This option includes devices with multiple coils submerged into the tank liquid.

 

3 – Single Upper Coil

This option includes devices with a single coil located above the liquid level in the tank and soaked with an e-liquid through a wick.

 

4 – Multiple Upper Coils

This option includes devices with multiple coils located above the liquid level in the tank and soaked with an e-liquid through a wick.

 

5 – Single Inserted Coil

This option includes devices with a single coil inserted from the power supply side in a porous tank filling material soaked with an e-liquid.

 

6 – Multiple Inserted Coils

This option includes devices with multiple coils inserted from the power supply side in a porous tank filling material soaked with an e-liquid.

 

7 – Coils absent (Instead of a classical coil, an ultrasonic membrane is used)

This option includes devices in which there is no classic coil or wicking. As a vapor generator, an ultrasonic membrane is used that converts the liquid into an aerosol.

8 – Coil and Ultrasonic membrane

This option includes devices that do not have a classic coil or wicking. As a vapor generator, an ultrasonic membrane is used that converts the liquid into an aerosol. To liquefy a viscous fluid, a pre-heating coil is used.

9 – Mash Coil

This option includes devices that do not have a classic coil or wicking. As a vapor generator, an ultrasonic membrane is used that converts the liquid into an aerosol. To liquefy a viscous fluid, a pre-heating coil is used.
