UL 4200A于2015年2月发布至今，已经历了5次修订。在CPSC发布要求之前，许多终端产品标准已经明确指出，产品若含有纽扣电池须满足UL 4200A要求。这些终端产品标准包括UL 1082，UL 982，UL 1026，UL 1081，UL 507等。此次CPSC发布的规范进一步扩大了UL 4200A的强制使用范围。只要产品包含纽扣电池，就需要满足UL 4200A的要求。

目前FCC Logo有新的变化么？目前FCC logo并没有新的变化要求，依旧如FCC官网说明，共有2种LOGO，如下图所示：1.https://www.fcc.gov/Logos 网页有提供了三种不同颜色的FCC Logo（F为锐角）‍‍‍‍2.KDB 784748 D01的第2.5 FCC Logo章节产品设备上应该用哪种FCC Logo？所有经过SDoC测试的产品上应该使用 KDB 784748 section 2.5中规定的FCC Logo（黑色直角），即第二种，如下图所示：锐角的FCC Logo是用在哪些地方？经与TCB确认，锐角的Logo是FCC官方专用，所有FCC官方发布的正式文件，都会有FCC的徽章或Logo。如果现有产品设备上的FCC Logo用成锐角的FCC Logo有什么影响？FCC官方回复产品上的label要使用KDB 784748中规定的黑色直角LOGO，已经出货的产品使用了锐角的FCC Logo也无风险，但是建议客户在后续的产品label上更正为正确的FCC Logo。
