Re: [PSES] CE Marking HDMI Cables

Hello Scott, There are U.S. and Canadian national differences to many safety standards that mandates flame resistance for cables such as this. Cables under 3.05 meter in length must be VW-1 or FT-1 or better in flame rating. (Longer cables are subject to stricter requirements.) This is why you

Re: [PSES] CE Marking HDMI Cables

My opinion is only the RoHS Directive should apply. But my last email from the ODM tonight says the cables have UL Approvals too, on the cable, on the connector and then flammability on the assembly. So they think that there must be some safety directive that applies (and was not tested for).

[PSES] CE Marking HDMI Cables

I am going around with an ODM making a HDMI cable for us. Standard cable just has our brand logo molded in the connector shell. Cable is to be used with Category 4 (ITE) Equipment and is sold separately. The question is CE Marked or not CE Marked. I say it must be CE Marked and they say not

Re: [PSES] F 155 enamel wire

Scott, Ted is correct. You must work to separate the concepts in your thinking. Functional insulation is that insulation required for the device to function and has identified insulation properties. Insulation used for safety purposes has a set of properties that ensure

Re: [PSES] F 155 enamel wire

Hi Ted, TIW is quite commonly used in the transformer of SMPS. For motor windings, enamel wire is still a mainstream material in use. Regards, Scott On 4 January 2018 at 22:42, Ted Eckert wrote: > Hello Scott, > > > > The enamel provides functional insulation for

Re: [PSES] F 155 enamel wire

Hello Scott, The enamel provides functional insulation for the wire allowing the coil to work as intended. However, the enamel is not to be relied upon for the purposes of safety. Triple insulated wire (TIW) was developed partly to address this issue and it is used where there must be basic

Re: [PSES] F 155 enamel wire

Hi Brian, Will look for the stds for understanding the meaning. It is interesting that an enamel coating is not necessarily considered insulation. If enamel coating is not necessarily considered insulation, the coil inductance, Q factor, energy dissipation, etc. will be affected. How does the

Re: [PSES] F 155 enamel wire

Thanks for your advice! Google search does give plenty of info but may not be the one I want. Your example consists rich info but there are not the ones I am looking for. Probably I did not fully understand those industry terms and looking for additional guidance. Regards, Scott On 3 January

Hi David, I guess that the latest version of EN 55014-2:201 is not listed in the OJ is due to bureaucratic nitpicking. If you check for this standard document on CENELEC's website, you will find that it has been developed under EU's mandate M/404
