[PSES] 答复: Low voltage DC electrical wire and cables require CCC approval?
Chuck, According to the voltage, it should be outside of CCC category. But if you want to be 100% sure, you still need to check the standard. The corresponding IEC standards are IEC60227-3/-4/-5/-6/-7 and IEC 60245-3/-4/-5/-6/-7. Some of the GB standards have no corresponding IEC standard so it’s difficult to check.

Paul and Chuck, To be 100% sure, best is to submit the cord set specs to CQC with intended application and HS code and hear back from them. It will save you much headache down the road.

[PSES] EN 55022 and CISPR 16-1-4 above 1 GHz (again)
List members, There was a lot of push-back at the original EN 55022 / CISPR 16-1-4 method for measuring above1 GHz and implementation was delayed (as I recall). Do the changes to the latest CISPR 16-1-4:2010 address the measurement method any differently? Absorber still required on the floor between horn and DUT?

[PSES] Safety cost and ESD
Given the implementation differences between US/Canada(?) and EU on the medical 60601-1 standards. EU the June, US June 2013. How are folks handling new products being introduced now or in the very near future? Just got a quote back and the US certifier wants to charge me twice once for the 2nd edition and then to transition to the 3rd edition. I anyone else running aground on this. Seems like this should be happening on both sides of the pond - since a CB report to 3rd edition would run into the second edition enforcement in the US (and maybe Canada - I don't know their implementation date). To be fair - I get good service once I get past the sticker shock and don't have any complaints from that standpoint. In fact I enjoy the engineering staff I work with. Different question about ESD. I have a component we tested on the normal 55024 directed ESD table for a table top mounted device. Worked fine, problem is that the customer places this on a large metallic roll around pedestal on rubber wheels. When they send it to a lab and test it this way there is a problem. I don't have the pedestal so I'm trying to simulate with my table and removing the 1 mohm bleeder resistor. Between discharges to the table, I ground a braided strap attached to the table top to my reference plane below. I get very similar results then. What should the braid really look like - should it just be a short, should it have some bleed resistance in it. I chose none since the discharge is going to be people touching the pedestal or other furniture that is grounded. What does the standard say about the VCP and HCP?
