    随着美国消费品安全委员会（CPSC）要求所有平衡车产品必须符合UL 2272认证标准，UL——全球领先的安全测试机构——在其官网上表示，到目前为止，没有任何一款平衡车产品得到其安全认证，并且提示称，UL对平衡车产品中电池组或电源等零部件的认证，并不等同于对平衡车产品本身的认证。不过UL已从2016年2月2日起，开始受理平衡车产品根据UL2272新标提交的电路及起火安全测试。
8 z" k9 H/ Y6 u* {( V    另据美国网站RetailDIVE分析，一直以来平衡车及其各种设计的监管法规缺失，造成相关官员很难分辨其中具有危险性的产品，也无法就如何使用产品才能确保安全提出任何建议。鉴于这些平衡车都产自中国，因此相关官员透露，他们希望与中国政府一同解决这个问题。尽管如此，消费品安全委员会的公开信将造成平衡车在今后的销售更加困难，至少在美国市场如此，直到制造商能够生产出一款消除起火和安全隐患的产品。

THE FACTS ABOUT HOVERBOARDS AND UL TESTING
Our public safety mission is at the forefront of everything we do, and it is important that information about our safety testing and certification remains transparent and factual. One of UL’s goals is to help provide peace of mind to consumers, retailers and manufacturers, and to work to make the products bought, sold and produced safer for use.
& `% U% M/ e7 C; Z+ ^' u7 iWHAT IS CAUSING RECENT SAFETY INCIDENTS?

Media reports state hoverboard fires may involve the lithium-ion battery and/or compatibility with the power supply. The Consumer Products Safety Commission (CPSC) is investigating the root cause of these incidents and will share more information as it becomes available. Consumers should report any hoverboard incidents to the CPSC via www.SaferProducts.gov.

7 ?" i& J& g1 |, m7 DWHAT CAN I DO TO AVOID AN INCIDENT?

A number of agencies, including UL, are dedicated to providing safety tips and advice for those who have purchased or been given this device. UL recommends:

• Keeping the hoverboard away from flammable materials while charging.
• Do not overcharge the board. Follow the manufacturer’s recommend charging times.
• Do not charge the hoverboard overnight.
• Use only the charger that is packaged with the hoverboard.
• If an incident does occur, it may be incorrect to use a fire extinguisher due to the nature of battery chemical fires. Instead, leave the area and call 911.
  

/ K" P- ^7 P4 `2 k% W! i( H8 EWHAT IS UL DOING ABOUT COUNTERFEIT PRODUCTS?

UL is committed to keeping potentially unsafe products away from consumers by supporting government and law enforcement agencies, like U.S. Customs and Border Protection, to seize products with counterfeit UL Marks and prosecute the criminals responsible.

WHAT KIND OF BATTERY TESTS AND CERTIFICATIONS ARE CURRENTLY CONDUCTED BY UL?

UL’s work in helping assure the safe manufacture, handling and use of new technologies includes a variety of tests on the energy storage system (such as batteries in stationary/motiveand portable applications), power supply, materials and system itself. UL has the foremost battery experts and has been extensively studying lithium-ion technology. Effective February 2, 2016, UL is accepting self-balancing scooters/hoverboard products for testing to the newly developed requirements (UL 2272) for electrical and fire safety. For more information on UL’s product testing, please also visit our pages forconsumer applications, commercial applications, power supplies andmaterials. It’s important to note that manufacturers voluntarily choose to submit these products for testing and certification as there is no mandate to do so.

FACT 1To date, UL has yet to certify any hoverboard for safety. However, ULannounced February 2, 2016 that with the development of UL 2272 – Battery Systems for Use in Self Balancing Scooters, the company has developed initial requirements for mitigating fire and electric hazards for these products. UL is now ready to support retailers and manufacturers in testing hoverboards and their components for electrical & fire safety. In parallel, UL has begun the consensus process to gather industry manufacturers and interested stakeholder groups in order to further the requirements that cover self-balancing scooters and similar devices.

& y( w! R/ ]3 d' Y# FFACT 2UL certification of components (such as a battery pack or a power supply) in hoverboards is different from certification of the hoverboards themselves.

: |4 ]; I8 |: E2 J) nFACT 3For technology using batteries, including hoverboards, it is important to understand and evaluate safe interaction among components. The testing requirements for UL 2272 specifically evaluate the safety of the power supplies and of the battery packs used in context of the whole system.

FACT 4The CPSC issued a letter to manufacturers, importers and retailers of hoverboards to urge them to make certain that the self-balancing scooters they “import, manufacture, distribute or sell in the United States comply with currently applicable voluntary safety standards, including all referenced standards and requirements contained in UL 2272 – Outline of Investigation for Electrical Systems for Self-balancing Scooters.”
