With the popularity of nicotine salt technology, the e-cigarette service industry is about to have a high level of development in small cigarette technology. Very popular in the current market

In addition to the upgrade of atomization technology, the power supply vendors of the equipment have changed from the 18650 lithium polymer mobile phone battery to the more common built-in lithium battery in mobile phones. battery.

Of course, for the earlier 18650 mobile phone batteries, hot news related to mobile phone battery issues was frequently spread, which not only caused the opponents to frequently promote safety measures as a hot topic, but also caused consumers to become more concerned about e-cigarettes. Security is a big question mark.

As a result, the standards for e-cigarettes recently promulgated by the U.S. FDA and the safety regulations for accurate e-cigarette cell phone batteries

In order for the FDA to make statistical evaluations of the use of mobile phone batteries in specific products, the agency advocates that suppliers’ products should comply with UL8319 safety regulations. UL8319 is a standard for electrical appliances specifically used for electronic cigarette products to confirm the undervoltage or overvoltage protection of the product.

Moreover, the agency also encourages suppliers to indicate the current intensity, voltage, power, cell phone battery type (chemical nature), whether the cell phone battery can be replaced by consumers when submitting the application process, and various testing methods for cell phone batteries or equipment. Information about the standard way.

In May 2017, the American Standards Committee published information that the UL8139 standard was selected as the standard for e-cigarettes. In June 2018, UL, the global leader in safety science, announced that UL8139, the safety standard for e-cigarettes, has been trusted by the American Standards Association and the Canadian Standards Committee, and has been officially selected as the recommended standard for e-cigarette products to enter the US market.

The scope of UL8139 is as follows:

1. Select whether the lithium battery can be used within its safety rating range;

2. Statistically evaluate whether the mobile phone battery management system (BMS) can be used in a variety of ways, whether it can be a problem caused by the predictable misuse of consumers;

3. Statistically evaluate the compatibility between most modes. Full consideration is given to the environment and conditions that consumers may choose;

4. Therefore, it is expected that the mechanical stress test will be carried out in the case of imagined selection and foreseeable misuse;

5. Fully supplement the product description of market operation to realize the safe selection;

6. It is necessary to set the mobile phone battery discharge channel in a targeted manner, and the mobile phone battery discharge is away from the direction of the cigarette holder, which has alleviated the problems of consumers;

It can be seen that the FDA hopes to respond to safety measures at an earlier stage of device development. Through UL’s product certification, the industry can detect and correct design defects as soon as possible. Not only can the problems caused by the product be reduced to a greater extent, but also the corporate reputation of the company can be confirmed in many aspects.
