Youdaoplaceholder0 Local requirements ? : In regions such as the Beijing-tianjin-hebei area and the Yangtze River delta, additional ? regional environmental protection standards ? (such as AQI linked alarm) may be added.

Appendix: A Guide to Avoiding Pitfalls

? beware of "conforming to old national standards" (such as GB/T 18883-2002 which has been abolished).

? international brands need to confirm the Chinese localization certification (such as CCC compulsory certification) additionally.
