How much actual new testing will be required to move from product investigations currently to IEC 60950-1 to IEC 62368-1?
Unfortunately, this sort of question cannot be addressed in depth in this sort of forum since the answer is mostly dependent on the specific product type (construction, function, complexity, components involved, etc.) and resulting application of theStandard. Although studying and becoming familiar with 62368-1 is a good first step (starting with a review of Clause 0 and Annex W), a Gap Analysis also would be a prudent activity in learning to apply the standard to products your company produces. We have provided many such analyses on a wide scope of products for a wide variety of manufacturers.
