Technical testing

Puff Count Test

This test aims to count maximum puffs from one cartridge, pod, or device. This method includes the requirements found necessary for the generation and collection of e-cigarette aerosol for analytical data.

Puff count is a group of tests. The first is a simple puff count with or without adjusting the number of puffs. The second group of tests is aimed at studying the life cycle of the test taker. The device to be tested is connected to the machine and works until the battery is discharged, or the liquid runs out, and it’s detected automatically by a special sensor.

Pressure drop test

The goal of the test is to find the difference in suction force during puffing. This test determines the amount of force that must be applied for a single puff.

Methodology puff protocol:

1. The airflow rate required to produce the aerosol and the density of the aerosol can vary depending on the number of puffs.
2. The total area of ​​the air holes correlates with the pressure drop for some brands.
3. Smoke-out protocol: E-cigarettes within a brand generally performed similarly when puffed to exhaustion; however, there was considerable variation between brands in pressure drop, airflow rate required to produce an aerosol, and the total number of puffs produced.
4. With this protocol, aerosol density varied significantly between puffs and gradually declined.

Evaporated mass during puff test (EMP test)

This test’s mission is to determine the amount of vaporized material during one puff.

This test is used for:
– determining the efficiency of the process of evaporating of an e-liquid, oil, or tobacco/herbal substance;
– helping to evaluate the dynamics of e-liquid/oil or tobacco/herbal substance consumption;
– making the comparative analysis of the effectiveness of several devices in the context of substance evaporation.

E-vapor density test

The test can show the visual and numeric differences in vapor density. During the test, experts find out how much vapor the device generates during puffing. The test’s results are used for next purposes:

– conclude the quality of the technical solutions used in the device’s airflow design;
– obtain information about vapor volume released during a single or a series of puffs;
– observe the qualitative change in the tightening force and the amount of vapor during the long-term operations of the device or declared sessions.

The test is useful both when comparing the performance of several devices of the same type, and when examining single devices

POD/cartridge leakage test

The test performs leakage analysis of the device’s cartridges (pods) under various environmental conditions, and it is used only for devices with removable cartridges (pods), as well as clearomizers, tanks, and other similar elements.

The main test is done under the low atmospheric pressure, which can occur during the transportation of devices by air. Additionally, research can be carried out in a static position of the cartridge (pod) and during vibrations.

The test results serve to detect the intensity of leaks (if any), make conclusions about the design features of the cartridge (pod) and, if necessary, develop recommendations for eliminating leaks.

POD/cartridge design and construction review

The analysis provides for detailed research of the external and internal elements of the cartridge (pod), including:

– the heating element as the main one;
– air chambers and channels;
– elements that provide liquid/oil supply to the heater (wicks).

The procedure includes complete disassembly of the cartridge (pod) followed by photographing of its elements and expert analysis of the elements. Special attention is paid to heating elements, internal construction elements, and wicks, identifying unique technical solutions.

This type of research can be performed during the research of removable or built-in cartridges (pods), as well as clearomizers, tanks, and other similar elements.

Operational temperature of heating element test

The test allows determining the real temperature on the surface of the heating element, and, provides additional information:

– the operational modes of the electronic circuits of the device;
– design features of the heater, and its surrounding elements.

After the test, it is possible to detect overheating of the liquid or tobacco/herbal substrate, since overheating can lead to the formation of harmful chemical compounds in the vapor.

Depending on the type of heating element used in the device, measurements can be carried out using a high-precision pyrometer or using miniature thermocouples.
The test can be used in the research process of any type of vape device:

– pod-systems;
– HnB;
– oil vaporizers.

It should be noted that due to the design features of some devices (pod-systems and similar ones with replaceable evaporators (cartridges)), this test may be difficult to perfor

Internal components and design review

The test is due to make research the device’s features and technical solutions used in it.

During this test, complete disassembly of the device is performed followed by photographing of the assembled internal layout, as well as photographing of individual elements and structural units. This research can provide a more detailed analysis of the device’s certain components, measurements of the element’s parameters, and analysis of used materials.

Additional technical diagnostics can be carried out to identify non-standard technical solutions and characteristics of the device. The analysis can be provided for any type of vape device: pod-systems, HnB, oil vaporizers, etc.

Device Drop Test

The test is carried out to determine the strength of devices under various conditions of mechanical stress on them. The investigation is carried out using a drop machine by throwing the device from a height of 122 cm on certain sides or corners of the device.

Based on the results of this research, it is possible to resume the reliability of the structural elements of the device, the quality of its assembly, the quality of the materials which are used in the device’s structural elements.

The test can be used in the research process of any type of vape device: pod-systems, HnB, oil vaporizers, etc.

Button failure test

The test of mechanical buttons of vaporizers and e-cigarettes for lifespan is performed for the determination of the life cycle of buttons that can be used in certain vape devices.

The test involves carrying out a large number of button presses using a specialized automatic machine until mechanical damage to the button or loss of electrical contact between the internal elements of the button occurs.

Based on the results of the research, it is possible to make conclusions about the quality of the device’s buttons, which directly affects the life cycle of the device as a whole.
