Summary of Vaporizer Attributes
This section includes description of the second group of attributes applicable to vaporizers of CLs, APVs, EHs and HWOVs. This group is coded using three alphanumeric symbols for CLs or four alphanumeric symbols for APVs, EHs, or HWOVs.
Hyphen (-) is used in our classification system as a divider between the second and third groups of symbols. Continuing the example shown in Section 1.4 for a modular APV with a serviceable coil and a threaded connector, the first and second code groups (with the dividers between the first and the second and the second and the third groups) for APV of this category with a single-section clearomizer and high output, with external control, adjustable air flow, non-adjustable liquid feed and multiple upper coils, we designate this device with the following first two code groups and respective dividers:
