Do We Really Need a New Safety Standard?

Figure 1: IEC/EN 62368-1 is not a merge of the two standards IEC/EN 60065 and IEC/EN 60950 but a completely new one introducing a new way of working

Safety regulations have been in place for decades in the power industry and as we know only too well, all have been through lots of revisions. And although each revision has made them more stringent and tailored to our businesses, we have become familiar with designing products to conform to latest versions.
