Vaping Reliability Test Checklist: What Tests Does Vaping Need?

Checklist of reliability test items for vaping products: what tests does a vaping product need? The aspects of vaping products that have always attracted the most attention are flavor experience and safety. Vaping products require testing in every area, including raw material selection, the use of additives, and process planning. A finished product is created through repeated testing and experimentation on multiple samples, allowing adjustments to achieve the ideal flavor experience.
 
The reliability testing items for vaping product samples are generally divided into three parts: the finished vaping product, the atomizer, and the battery. However, as vaping product structures continue to evolve toward integrated designs, the test items for finished products have almost merged with those for atomizers.

I. Finished vaping product

The flavor experience of a vaping product is generally evaluated based on puff count, airflow, vapor production, whether it leaks e-liquid, whether there is any burnt taste, and the surface temperature during heating—namely the operating temperature where the product comes into contact with the user.

1. Puff count

Test the e-liquid puff counter.

Automatic smoking machine: automatic vaping test machine for testing e-liquid.

2. Airflow

Manual vaping: test the e-liquid and confirm smooth airflow during inhalation.

Automatic smoking machine test for e-liquid: set the device timer for puff duration and pause duration, for example, inhale for 2 seconds and pause for 5 seconds; test the machine suction when vapor production is in acceptable condition.

3. Vapor production

Manual vaping: subjective assessment of vapor production.

4. E-liquid leakage

Manual vaping: no e-liquid should be drawn into the mouth.

Vibration test: bare product vibration frequency ** times/minute, packaged product vibration frequency ** times/minute; no e-liquid leakage at the mouthpiece or light cap.

5. Burnt taste

The tested e-liquid must not produce any burnt taste or other unusual odor.

6. Operating temperature

Automatic smoking machine: while the product is in vaping mode, use the temperature probe to contact the outer wall of the atomizer heating element and measure the real-time temperature.

II. Atomizer

1. Resistance value

Use the positive and negative terminals of a digital bridge meter to contact the atomizer electrode and atomizer thread respectively to measure resistance.

2. Airflow

Manual vaping: test the e-liquid and confirm smooth airflow during inhalation.

Automatic smoking machine test for e-liquid: set the device timer for puff duration and pause duration, for example, inhale for 2 seconds and pause for 5 seconds; test the machine suction when vapor production is in acceptable condition.

3. Vapor production

Manual vaping: subjective assessment.

Automatic smoking machine: adjust the standard sample to the proper vaping condition, set the device timer for puff duration and pause duration, and if vapor production meets the requirement, it is OK.

4. E-liquid leakage

Manual vaping: no e-liquid should be drawn into the mouth.

Vibration test: bare product vibration frequency ** times/minute, packaged product vibration frequency ** times/minute; no e-liquid leakage at the mouthpiece or light cap.

5. Burnt taste

The tested e-liquid must not produce any burnt taste or any unusual odor.

6. Operating temperature

Automatic smoking machine: while the product is in vaping mode, use the temperature probe to contact the outer wall of the atomizer heating element and measure the real-time temperature.

III. Battery

The battery testing referred to here does not mean testing the battery independently, but rather checking whether the battery meets the requirements of the overall product.

1. Battery capacity

Use the positive and negative clips of a battery capacity grading instrument to connect to the battery's positive and negative tabs respectively.

2. Static current

Static current of the battery control board and static current of the battery cell.

3. Charging function

The power supply output voltage and current must match the charger input voltage and current.

4. Vaping function

During vaping, the LED light should turn on, and the atomizer's vapor production should be no less than that of a traditional cigarette. For variable-voltage batteries, the maximum and minimum voltage adjusted by rotating the tail end should comply with the standards in the product specification sheet.

5. Overtime puff protection

According to the battery continuous working time standard in the product specification sheet, press and hold the battery power button while vaping. When the maximum continuous working time under operating conditions is reached, the LED flashes * times and output is shut off.

6. Short-circuit protection

During vaping, if the heating wire short-circuits, the battery provides no output and the LED flashes * times. #p#Page Title#e#

7. Low-voltage protection

When the battery voltage falls below the minimum voltage standard in the product specification sheet, pressing the vaping button will cause the LED to flash * times to indicate low battery, and the battery will provide no output.

8. Charging protection

When the battery voltage reaches its rated level during charging, charging is automatically disconnected internally to prevent overcharging.

9. Overcurrent protection

When the battery is under load and the discharge current exceeds the standard required for the vaping product, the battery automatically powers off and stops discharging.

10. Charging time

The standard time required to charge the battery from a low-voltage state to full charge.
