Table 41.1 Assumed Touch Voltage

I am a bit confused by this. Why do the disconnection times in Table 41.1 appear to be based on a touch voltage of 100 volts rather than a touch voltage of 125 volts?


For example, 110% of 230=  253 volts. Assuming L and PE are of the same size and material, indirect contact touch voltage is 126.5 volts. Would 0.33 seconds not appear more realistic?  


From IEC 61200-413

  • The handle cranking money making machine is indeed a common gesture in certain circles. ? (I did do quite a bit of standards related work for Siemens Mobile and then the base station part for a  while in the early 2000s). Having worked on standards for 3G telecoms (3GPP) it is much the same in process as you describe  but much cheaper. The interested parties, the telcos, the manufacturers of handsets and some national bodies like Ofcom and the occasional "independent" ? from a security related organisation  are all paid for by their organisations, and generate the content of the standard in effect for free. The ETSI did some editing, merging and admin to do with version numbers, between meetings, and the standards appear  free to download on the internet shortly before the next meeting to change them again.

    I firmly believe that  if it was not for the problem of paying for those extra folk in the chain who feel entitled to a regular income and have become accustomed to a rate of spend that matches it, you could do the same with the IEC stuff.
