Summary of overall device attributes

Category (symbol 1-1)

1.1 Introduction category (symbol 1-1)

In our classification system, power supply is assigned an individual category (P) without breakdown into smaller subtypes while the vaporizer or the vaping device category is determined as a combination of unit type (vaporizer, CL, APV, EH, HWOVs or HDs) and subtype (refillability for vaporizers, CLs, APVs and EHs; and coil serviceability for vaporizers, APVs and EHs). As discussed in Introduction, both coil serviceability and refillability are characteristics of vaporizers; however, they are included into the overall device attribute category since they are primary factors that determine the entire vaping device design.

The only serviceable part of a serviceable unit is a coil-and-wick assembly and a serviceable unit is a unit with serviceable coil(s). Term “serviceable unit” is used sometimes hereinafter for brevity as a short description of a unit with serviceable coil(s).

Both disposable units and units with disposable cartridges are classified as non-refillable, while all partially serviceable and serviceable units are refillable. Therefore, only four combinations of serviceability and refillability (non-serviceable non-refillable, non-serviceable refillable, partially serviceable (always refillable) and serviceable (always refillable)) are possible for vaporizers, APVs and EHs. All CLs are non-serviceable.

HWOVs are divided into subcategories that can use dry herb substance, wax or oil, or only wax or oil as a consumable.

Based on these comments, we introduce three subtypes for vaporizers, 2 subtypes for CLs and 4 subtypes for vaporizers, APVs and EHs. This symbol includes no further breakdown of HWOVs or power supplies into subcategories.

Therefore, ‘Category’ is designated with the following 20 alphabetic options under the first symbol of the Overall Device Attribute group:

B – Cig-a-like, non-refillable
C – Cig-a-like, refillable

D – Vaporizer, with non-serviceable coil(s), non-refillable
E – Vaporizer, with non-serviceable coil(s), refillable

F – Vaporizer, with partially serviceable coil(s)
G – Vaporizer, with serviceable coil(s)

H – E-hookah, with non-serviceable coil(s), non-refillable
I – E-hookah, with non-serviceable coil(s), refillable

J – E-hookah, with partially serviceable coil(s)
K – E-hookah, with serviceable coil(s)

L – APV, with non-serviceable coil(s), non-refillable
M – APV, with non-serviceable coil(s), refillable
N – APV, with partially serviceable coil(s)

O – APV, with serviceable coil(s)
U – APV, without Coil(s), Refillable (Instead of a classical coil, an ultrasonic membrane is used)
T – APV, with Coil at U-sonic Membrane, Refillable

P – Power supply
V – Herbal vaporizer
W- Wax and Oil vaporizers
Y- Hybrid Devices

As shown in the introduction, “X” is reserved for coding the ‘Inapplicable’ option. This option cannot be used for symbol 1-1 as any device should fall under one or another category. However, we are not going to use “X” in the future for future expansion of the option list for symbol 1-1, because this option is solely allocated for coding the ‘Inapplicable’ option for other symbols.

1.1.1 Evaporators / Vaporizers (Es)

The Evaporator category includes units designed to convert e-liquid into vapor.

D – Vaporizers, with Non-Serviceable Coil(s), Non-Refillable
These devices do not allow for service of their coil(s) or tank refill with e-liquid. When the tank pre-filled by the manufacturer is spent, it can either be replaced, or the entire vaporizer should be disposed of.

E – Vaporizers, with Non-Serviceable Coil(s), Refillable
These devices do not allow for service of their coil(s) and allow for tank refill with e-liquid.

F – Vaporizers, with Partially Serviceable Coil(s) (always Refillable)
When a coil element of this unit loses its functionality after expiration of its service life, a unit atomizer can be replaced and unit service may continue. These devices allow for tank refill with e-liquid.

G – Vaporizers, with Serviceable Coil(s) (always Refillable)
These devices allow both for service of its coil(s) and/or tank refill with e-liquid.

1.1.2 Power supply (Ps) assemblies

P – Power Supplies

The Power Supply category includes modules designed to supply electric power to vaporizers. A vaping device can be powered by a variety of power supplies. For example, the most common APVs involve the use of 3.7 V rechargeable lithium batteries, which deliver a noticeably higher voltage than that found in a typical cig-a-like battery. It is also possible to use multiple batteries and controls to increase voltage even higher. These multiple batteries are usually connected to a push button switch that controls power delivery to the connector that a vaporizer is joined to.

1.1.3 Conventional-look devices (CLs)

Conventional-look ENDS (cig-a-likes) are devices that, in their appearance, resemble conventional tobacco products such as cigarettes, cigars, cigarillos and/or little cigars.


B – Conventional-Look Devices (CLs), Non-Refillable

These devices do not allow for tank refill with e-liquid. When the tank pre-filled by the manufacturer is spent, it can either be replaced, or the entire CL should be disposed of.


C – Conventional-Look Devices (CLs), Refillable

These devices allow for tank refill with e-liquid.

1.1.4 Advance personal vaporizers (APVs)

APVs are the devices that combine a vaporizer and a power supply assembly within a single housing and do not resemble, in their appearance, conventional tobacco products such as cigarettes, cigars, cigarillos and/or little cigars.


L – Advance Personal Vaporizers (APVs), with Non-Serviceable Coil(s), Non-Refillable

These devices do not allow for service of their coil(s) and do not allow for tank refill with e-liquid. When the tank pre-filled by the manufacturer is spent, it can either be replaced or the entire unit should be disposed of.


M – Advance Personal Vaporizers (APVs), with Non-Serviceable Coil(s), Refillable

These devices do not allow for service of their coil(s) and allow for tank refill with e-liquid.


N – Advance Personal Vaporizers (APVs) with Partially Serviceable Coil(s) (always Refillable)

When a coil element of this unit loses its functionality after expiration of its service life, a unit atomizer can be replaced and unit service can continue. These devices allow for tank refill with e-liquid.


O – Advance Personal Vaporizers (APVs), with Serviceable Coil(s) (always Refillable)

These devices allow both for service of their coil(s) and/or tank refill with e-liquid.


U – Advance Personal Vaporizers (APVs), without Coil(s), Refillable

This option includes devices that do not have a classic coil or a wick. As a vapor generator, an ultrasonic membrane is used that converts the liquid into an aerosol. These devices allow for tank refill with liquid.


T – Advance Personal Vaporizers (APVs), with Non-Serviceable Coil at U-sonic Membrane, Refillable

This option includes devices that do not have a classic coil or a wick. As a vapor generator, an ultrasonic membrane is used that converts the liquid into an aerosol. To spray a viscous liquid with an ultrasonic membrane, it is heated by means of a coil. The coil is not serviceable. These devices allow for filling the reservoir with e- liquid.

1.1.5 E-Hookahs (EHs)

E-Hookahs are devices that resemble, in their function, conventional hookahs.


H – E-Hookahs (EHs), with Non-Serviceable Coil(s), Non-Refillable

W – Wax and Oil Vaporizers

This code is assigned to Oil and Wax vaporizers of various types. This is a device designed for vaping a wax or oil blend. Various mechanisms of heat transfer (thermal conductivity, convection or thermal radiation) are used in the wax vaporizers to heat wax and oils blends.

1.1.7 Devices that combine in one case AVPs and Herbal vaporizer -Hybrid Device (HDs)

Y – Hybrid Devices

This code is assigned to Hybrid Devices of various types. A hybrid device is a device in which two different technologies are combined, one of which is based on the evaporation of a liquid, and the other is based on the heating of a dry plant substance. As a result, the vaporized vape is mixed with the active substance, which is released by heating a dry plant substance.

Architecture (symbol 1-2)

1.2 Introduction (symbol 1-2)

We define architecture as a combination of device modularity (single-piece or modular) for vaporizers and all five vaping device classes (CLs, APVs, EHs, HWOVs and HDs) and a type of connector between the unit vaporizer and power supply for vaporizers, power supplies, CLs, APVs and EHs. It is designated with ten numeric options assigned to the second symbol of the Overall Device Attribute group.


The meaning of the “Single-Piece” and “Modular” terms is different for vaporizers and each class of the vaping devices. Specifically, when this option is selected for a vaporizer, it means that this vaporizer is built as a single-piece unit. When the same option is selected for a vaping device, it means that this vaping device is built as a single-piece unit. For example, a refillable single-piece vaporizer with non-serviceable coil and a coaxial connector of subcategory E2 can be used as a major component of a refillable modular single-piece APV with non-serviceable coil and a coaxial connector of subcategory M5.


Since the coding system is different for different major components and vaping device classes, we begin code description with listing codes for each device category:


Es

1 – Single-Piece, Without Connector

Summary of overall device attributes

Content

1.3 Summary

This chapter includes a description of the first attribute group that is applicable to all the devices of each class. The first three symbols of our coding system are allocated to this attribute group for each device class. The other two attribute groups are discussed in Chapters 2 and 3 for CLs, APVs, EHs, HWOVs, and HDs. Attributes of vaporizers and power supplies discussed in Chapters 2 and 3, respectively and coded as individual units are identical to their attributes when coded as major components of vaping devices.


Forward slash (/) is used in our classification system as a divider between the first and second group of symbols. For example, the first code group with a divider from the second group for a modular APV with a serviceable coil and a threaded connector is


O7/…


Codes presented in this chapter allow us for distinguishing between disposable and multiple-use devices. Specifically, single-piece non-refillable devices are disposable, while single-piece refillable and modular devices are multiple-use ones.


In the next two chapters, we discuss attributes of vaporizers and power supplies for all the five vaping device classes (CLs, APVs, EHs, HWOVs and HDs). Following the concept outlined in Introduction, when coding vaporizers or power supplies as individual units, we use the same codes when coding them within APV coding procedure as major APV components.
