Bulletin Subject:     Publication and adoption of China GB 4943.1:201X (harmonized with IEC 60950-1: 2005)
                                            
Effective Date of Change: March 16, 2012
; a9 ~$ l  R$ C' z! D; h" lSUMMARY: 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.

' X7 {/ J8 b- m  c% b  tIMPACT: 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.

( I: |3 ]: a6 r2 O2 Z# w/ s1). 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 J1 P  I2 o0 J. X) s3 Z( y" JThis 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.

3). 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.

4). Altitude and clearances: For China, the clearances ( through air electrical spacings ) must be suitable for 5000 m. 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.

  X" r$ v7 @/ d7 \# @# Z5 PNOTE – 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.
