Requirements for safety specifications of electronic cigarette batteries.
With the popularization of nicotine salt technology, the electronic cigarette service industry is about to experience a high level of development in small cigarette technology. It is very popular in the current market
The electronic cigarettes not only have upgraded atomization technology and various rack structures that are different from classic electronic cigarette products, but also the power supply sellers of the equipment have shifted from the 18650 lithium polymer mobile phone battery in the past to the more common built-in lithium battery in mobile phones.
Of course, as a result, the early 18650 mobile phone battery often spread hot news related to the issue of mobile phone batteries, not only causing opponents to frequently publicize safety measures as hot topics, but also causing consumers to question the safety of electronic cigarettes to a large extent.
Therefore, the recent standards for electronic cigarettes issued by the US FDA, as well as the safety specifications for accurate electronic cigarette mobile phone batteries.
In order to potentially assess the use of mobile phone batteries in specific products, the FDA advocates that suppliers' products should comply with UL8319 safety regulations. UL8319 is a standard specifically designed for electrical appliances used in electronic cigarette products to confirm the product's undervoltage or overvoltage protection.
Moreover, the organization also advocates that suppliers indicate information such as current intensity, voltage, power, type of mobile phone battery (chemical properties), whether mobile phone batteries can be replaced by consumers, and various standard methods for testing mobile phone batteries or devices when submitting application procedures.
In May 2017, the American Standards Committee selected UL8139 as the standard for electronic cigarettes and released information. In June 2018, UL, the global leader in safety science, announced that the safety standard UL8139 for electronic cigarettes had been trusted by the American Standards Institute and the Canadian Standards Committee, and had been officially selected as the recommended standard for electronic cigarette products entering the US market.
The scope of UL8139 includes the following:
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 commonly use various options and whether it can avoid foreseeable problems caused by consumer misuse;
3. Statistically evaluate the compatibility between most modes. We have fully considered the possible selection environment and conditions for consumers;
4. Therefore, it is expected that the misuse of the chosen scenario and predictability in the implementation of mechanical pressure testing will occur;
5. Fully supplement the product description for market operation to achieve safe selection;
6. It is necessary to set up a targeted discharge channel for mobile phone batteries, and the discharge of mobile phone batteries should be kept away from the direction of cigarette butts to alleviate the problems of consumers;
From this, it can be seen that the FDA hopes to address safety measures in the early stages of device development. Through UL's product certification, businesses can detect and correct design defects early on, which not only minimizes the problems caused by the product, but also confirms the company's reputation in various aspects.
