Comparison between Kazakhstan's СНРК 2.04-29-2005 and China's GB 50057-2010

In this paper, the Kazakhstan's Lightning Protection Equipment Instruction for Structures and Facilities (СНРК 2.04-29-2005) was compared with China's Design Code for Protection of Structures against Lightning (GB 50057-2010). It is indicated that they are different in guiding ideology, lightning protection requirements classification of structures and lightning protection measures and materials. With respect to the guiding ideology, СН РК 2.04-29-2005 is constituted on the basis of the Protection of structures Against Lightning of traditional IEC 61024-1993 and French NFC17-1995 while GB 50057-2010 is based on Protection Against Lightning (IEC 62305). As for the lightning protection requirements classification of structures, both specifications are basically the same in terms of classification methods, but GB 50057-2010 is more stringent in value calculation. With regard to the lightning protection measures and materials, СНРК 2.04-29-20050 prefers independent lightning rods at oil/gas stations and it is generally junior in the specifications of lightning grounding materials. The difference should be considered carefully to control the engineering investment.
