( ?2 |5 l& B" P: kSUMMARY: The China GB 4943.1:201X (Chinese standard that is equivalent to IEC 60950-1, 2nd Edition with Chinese national differences) will become effective on March 16, 2012 for all products under the scope of IEC 60950-1:2005 that are applied with the CCC mark.

7 ]1 P2 Y1 _2 p7 h. D$ \. @& Y2 x, b& jIMPACT: All CCC certifications will need to be updated by March 16, 2012.  It is recommended that all submittals made after December 1, 2011 will be to this new standard.

Major changes: Following are the major Chinese national differences from IEC 60950-1 2nd Ed found in the China GB 4943.1 standard.

1). 1.4.5 - Tolerances on supply voltage: Tolerances are + 10% and - 10% instead of + 6% and - 10% as given in IEC60950-1. The China mains voltage is 220 V. Therefore, the test voltages under consideration are 198 to 242 V.

This will not have an impact if a product is marked with an input voltage range such as 200-240 V (servers are marked like this). This will have an impact a product is marked with a single input voltage such as 230 V or 115/230 V (desk top units are marked 115/230 V). In this case the heating test of 4.5 of IEC 60950-1 may need to be repeated at 198 V.

2). 1.7.1 - Marking of input rating: 220 V, 50 Hz for single phase; and 380 V, 50 Hz for 3-phase

This will not have an impact if a product is marked with an input voltage range such as 200-240 V. This will have an impact if a product is marked with a single input voltage such as 230 V or 115/230 V. The 220 V rating needs to be included in the marked rating.

* ~' s$ x7 X0 ^% f" U3). 1.7 - Safety instructions: All safety instructions and the associated text in the manual for the required symbols on the equipment must be in 5 Chinese languages. The 5 Chinese languages are Simplified Chinese, Tibetan, Mongolian, Zhuang and Uyghur.

Dell currently designs equipment for 3048 m ( 10,000 feet ). Therefore, (unless clearances for 5000 m are used) the following symbol and instructions must be provided. All Dell equipment with CCC marking is impacted unless we redesign the equipment for 5000 m.

4 m8 w- [! {8 c3 }$ k9 JNOTE – For example, for 230 V equipment the clearance required for basic insulation is 2 mm. Dell requires this clearance to be 2.28 mm. For China and 5000 m 2.96 mm would be the require clearance distance.

這個是客戶給出來的，我在相關網站也沒找到這點，真不知道是怎樣？

我在网站上也找不到。

要通告也要用中文才对吧

ican8848

WTO上公开而已
还没有正式发布呢

davidwang

这个已经公布，如果外界没有意义，可能今年年底就会实行。

这真实行的话，整的动静应该不会小！
