Thank you to all who replied to my recent post regarding Japanese EMC and safety compliance.
I have a follow-up question: The feeling that I get is that test and measurement equipment isn’t specifically regulated for safety in Japan. Although, the equipment should have been previously tested to an international safety standard such as EN 61010-1. I also am learning that most of the power plugs in Japan are ungrounded….here is where my follow up question comes in: I would assume that the Japanese deviations to international safety standards such as EN 61010-1 and EN 60950 would take this lack of ground connection into account. How is this typically handled for Class 1 products????? Does this mean that all products tested for Japan have to be Class II products? It seems hard for me to believe that manufacturers of computers would need to manufacture a Class I (grounded) version for most of the world and a Class II (double insulated, ungrounded) version for Japan. I have also heard that some Nordic countries have similar requirements, due to the lack of good Earth grounds in the permafrost and rock. Any thoughts?
