Hello good emc-pstc people:

I have a question about line isolation transformers for consumer audio 
products.  We are a transformer manufacturer, but the vast majority of our 
applications are for ITE equipment.  My question is, 

1)  for UL & CSA approvals, what standard does an isolation transformer need to 
meet for consumer and professional audio products?  I am currently referring to 
UL 1411 "Transformers and Motor Transformers for Use in Audio-, Radio-, and 
Television-Type Appliances".  I want to make sure that this is the correct 
standard, i.e. is it the most current standard?  What about for CSA?

2) for that matter, what about Europe?  Is there much movement in harmonization 
for approvals for this type of product between the US, Canada, and Europe?

Thank you much for all your help.
