About 20 yrs ago, I had exactly the problem that Rich outlines in paras 2 & 3, but in a somewhat different context, when I took on a job in the defence industry which appeared to require 60950 knowledge but then I found out (which the company did not really “get” for quite a few months/years thereafter!) that the real target requirement was for Hazard (severity/probability)-based safety cases for the UK MoD.
Took me a few years to get reasonably comfortable with the whole concept and its implications and intricacies – but that stood me in good stead in a number of the jobs that followed, and right up to the very last contract job which finished last year. In that case I had, again, to educate that part of the company into the whole process of risk assessment for 61010-1 evaluations as my predecessor had declared it to be “Not Applicable” because 1) he was an EMC engineer (J), & 2) he had no idea of what it involved and so, somehow, persuaded the management that it was “N/A” - whereas it was absolutely necessary because of the inherent issues in the designs of many products!.

Those familiar and experienced with 60950 will find 62368 very difficult. In my opinion, those who are new to product safety probably will find 62368 easier to understand. There are very few hardware differences between the two standards. The approach in 62368 is to separate the requirements (safeguards) according to “hazard” whereas 60950 has the requirements for different “hazards” mixed up so that someone who is applying the standard doesn’t know what the requirements protect against.

Which is more difficult to pass in product safety for IT equipment ? Hope to hear from you soon. Thank You & Happy Holiday.
