Re: [PSES] thoughts on ESD test lab problems

No way am I jumping in the middle of this debate, but it is extremely useful in another way. A few observations: ESD is by its very nature a chaotic event (air discharge more so than contact). It is not entirely surprising that someone who has spent decades working on something would

Re: [PSES] Friday Question - Line Cords in China

Yes, I have had China Customs open a shipment of 10 powered speakers and find one power cord was not from an approved manufacture on our critical components list. We were short one cord set so I had used an engineering sample… Had right plug and cordage, just not on our products components

Re: [PSES] Friday Question - Line Cords in China

Manufacturers cannot side-step liability by claiming ignorance. The manufacture is solely responsible for any product they place on the market, with or without the correct power cord. From: Douglas Powell Sent: Friday, August 11, 2023 7:53 AM To: EMC-PSTC@LISTSERV.IEEE.ORG Subject: Re:

Re: [PSES] Friday Question - Line Cords in China

How would the customs folks in those countries check appliance line cords ? Do they open boxes, pull contents, and inspect? If the USA plug is not rated for higher voltage, does it really present a hazard ? (compliance vs safety) The USA/Canadian plugs have a LOTS of creepage distance

Yes, I did find this topic on the EMC-PSTC archive. And yet it seems to come up over and over. Best regards, Doug Douglas E Powell Laporte, Colorado USA On Fri, Aug 11, 2023, 9:39 AM John Woodgate wrote: > I seem to remember this subject being extensively discussed about two > years ago.

[PSES] PSES] Friday Question - Line Cords in China

It maybe cheaper/less custom issues if local distributor can purchase line cord from the local market. Power supply should be certified for the country it is used in. Yes Brazil and South Africa line chord certification Leadtime are long and costly. Australia also has some conditions for

Re: [PSES] thoughts on ESD test lab problems

I didn’t say most labs are bad. Errors do happen and for me almost every lab I have used has made a mistake. These errors are rare but do happen and the effect of a single error can be very costly. One lab made an especially bad mistake for a small company that engaged me that cost the company

Re: [PSES] Friday Question - Line Cords in China

I seem to remember this subject being extensively discussed about two years ago. The bans on 'alien' cords are indeed enforced, and some authorities were extremely unhelpful in finding solutions, e.g. not allowing products to be shipped without cords, which were added in the country of

Re: [PSES] Friday Question - Line Cords in China

I believe you are correct. Simply shipping the wrong cord types to certain locations is actually prohibited, and in general, including incorrect types could be viewed as endorsement of their use in other areas. A thing that should be simple, now gets complicated. On occasion, I've heard

Re: [PSES] Friday Question - Line Cords in China

Hello Doug - Wow I had no idea that this issue existed. Thanks for bringing it up! As I understand that the inclusion of incorrect cords in a package spreads the incorrect conclusion that ALL of the cords are suitable for use. Did I get that right? On Fri, Aug 11, 2023 at 8:00 AM Douglas Powell

Re: [PSES] thoughts on ESD test lab problems

That's right. It is good to call attention to problems that may well be deeply hidden or not recognized as a possibility, but it is necessary to concentrate on the facts and leave out peripheral matters that don't help to deal with the issue. On 2023-08-11 14:28, Larry K. Stillings wrote: You

[PSES] Friday Question - Line Cords in China

All, I was talking with a client recently about shipping line cords to various countries around the world and how some do not allow the incorrect cords within a shipment while others do. Brazil, as far as I know, does not permit incorrect cordage. Argentina, Australia, and China (PRC) are all

Re: [PSES] thoughts on ESD test lab problems

Doug, Your once-a-year lab bashing is offensive, some years you do it more and honestly I'm tired of not saying something about it. It's especially offensive to people like myself whom has been running test labs for the last 33 years and pride myself in the work we have provided to our
