Amazon UL8139 test report application process on electronic cigarette

UL 8139 scope of application: UL 8139 touch electrical system test, including battery, charger, maintenance circuit and control equipment for battery safety, electric shock and fire hazard. UL 8139 does not aim at electronic cigarette consumables, such as electronic liquids, other aerosol substances, oil wool and other particulate substances, nor does it take into account the psychological and physiological effects of any product consumables. be careful! The battery detachable electronic cigarette is not within the test range of UL.

What are the requirements of UL 8139 for electronic cigarettes?

Structural safety: for the structure of the entire electronic cigarette, considering various risks such as scald caused by improper design, the atomizer and the battery in the cigarette rod cannot be replaced at will. In order to prevent personal injury caused by mistakenly starting when consumers carry e-cigarettes, the atomizer requires at least two independent starting mechanisms to strictly prevent the occurrence of continuous high current discharge of battery and continuous heating of atomizer.

Electrical safety: For the electrical system of electronic cigarette, simulate the safety problems that may occur under certain conditions, such as battery fire and explosion, charger overheating and short circuit, and confirm whether the battery cell operates in the rated operating range, to prevent the local temperature from being too high due to the long-term operation of lithium battery cell under the current and voltage conditions that exceed its rated value (including man-made or product quality problems), This will cause the battery to deflate or explode.

Operating instructions: For the operating instructions or the equivalent instructions of the device, sufficient information must be provided to the user to ensure that the device will not cause harm within the scope of this standard when used in accordance with the manufacturer's regulations. The safety instructions should be separated from the format of other instructions and should appear before the operating instructions. The instruction manual shall include correct instructions for use, including charging, storage and handling, and shall include environmental temperature limits; The equipment with rechargeable battery shall indicate the expected charger and any other relevant interfaces according to the manufacturer, model and series, and indicate the correct USB power connection, warning not to use unapproved power supply.

The main test items of UL 8139 standard include but are not limited to:

Electronic cigarette charging test

Smoking test

Overvoltage charging

Abnormal overcurrent charging

Smoke pole short circuit test

Temperature rise test

Waterproof test

Drop Test

There are also special test requirements such as extrusion test. For example, the electronic cigarette smoking test uses a smoking machine to simulate the actual situation of users' smoking. By monitoring the current, voltage and temperature of the battery in the electronic cigarette, it ensures that the battery works in a safe condition during the whole process of using the electronic cigarette; In consideration of the actual use, the temperature of the cigarette holder will also be monitored in real time during the test to ensure that the cigarette holder will not burn the user's mouth or any other body part due to the high temperature.

Amazon US station on the electronic cigarette also needs to provide the test report of UL 8139 standard, otherwise it may be audited and removed from the shelf. The UL certification fee is high. Amazon can make a test report of UL 8139, and the test laboratory should have ISO 17025 qualification.
