Greetings,

I understand that according to Japan's Electrical Appliance and Material
Control Law there are 2 "classes" of products, A or B. A type are considered
more risky appliances, and require a mandatory approval for the T mark. B
items are considered less risky, and do not require the marking. What we
have run into is that a regular air compressor is considered a B type
appliance, where as if we put an electrical control box on it to control the
inflation of a consumer product, then I'm being told by one source it has to
be a type A. Is there a clear list or definition of these categories? I was
searching the Net for information on Dentori, but have not found any sites.
Do you know of any good sites on Dentori? I've already spoke with UL, and
they quoted a price to do determine the category, but I think this
information should be available somewhere.

Thanks for your assistance,
