NBTC TS  10xx – 256x Page  2 of 3 3.3 Radiation Exposure Requirements 
The use of user equipment in cellular land mobile service using GSM- R technology 
shall comply with the safety standard for the use of radiocommunication equipment on 
human health and safety criteria and measure for the use of radiocommunication equipment 
on human health prescribed by NBTC.  
4. Conformity with the Standard
The user equipment in cellular land mobile service using GSM- R technology shall
present its conformity with these standards. It shall be regarded as telecommunication 
equipment Type B prescribed in the Notification of the National Telecommunication 
Commission on Conformity Assessment of Telecommunication Equipment. 
In addition, the conformity with the electrical safety standards shall apply to secondary 
batteries that are either installed in telecommunication equipment or contained in a package 
of such telecommunication equipment. It shall conform to either the TIS 2217- 2548 or 
current version or the IEC 62133 standard. 
Note  : 1.TIS 2217 -2548: Secondary cells and batteries containing alkaline or other non-
acid electrolytes - safety requirements for portable sealed secondary cells, and for 
batteries made from them, for use in portable applications  
2 .  IEC 62133:  Secondary cells and batteries containing alkaline or other non-
acid electrolytes - Safety requirements for portable sealed secondary cells, and
