Re: [PSES] NRTL approval

Ian,The common issues as to whether or not it needs a 3rd party safety approval is well argued outside of this email. By using a harmonized safety standard you will be able to have the Euro CE and North American NRTL evaluation all done at once and easily show needed compliance while

Re: [PSES] NRTL approval

Hi Ian: In the USA (and, presumably Canada), because the supply voltage is 5 volts dc, and the power is limited to about 15 watts, I believe the unit is exempt from NRTL certification. I have a number of USB powered products (e.g., keyboard, mouse, DVD, memory sticks, etc.), some of which

Re: [PSES] NRTL approval

As far as I am aware, the lower voltage limit will not be removed from the Low Voltage Directive. That being said, a significant fraction of products include Bluetooth, Wi-Fi or other radios, thereby

Re: [PSES] NRTL approval

Yes an interesting point is that ‘consumer’ use invokes the GPSD and could start to fall in to scope of "BS EN 60335-1:2012+A13:2017 Household and similar electrical appliances. Safety. General requirements" which has no ‘safe low voltage limit in it’ even though this is a LVD harmonised

Re: [PSES] NRTL approval

Hi Ian, Also my own words, (but shamefully stolen from our website): OSHA safety standards are part of US law and specify requirements for "approval" (i.e., testing and certification) of certain products by a Nationally Recognized Testing Laboratory (NRTL). The original intent of these

Re: [PSES] NRTL approval

Hi Ian: I have a vague recollection that the lower voltage limit either has been, or will be, withdrawn in the EU. The change may be specifically related to the use of EN 62368-1, but I can't recall where I saw it. Joe Randolph Telecom Design Consultant Randolph Telecom, Inc.

Re: [PSES] NRTL approval

Hello Ian, This is my unofficial answer, but if you were to email me at work, the answer would be the same ... OSHA regulations do not provide for limits on voltage or current, so any product that uses electrical energy must be tested and certified by a NRTL or otherwise determined

[PSES] NRTL approval

Dear colleagues. We are in the process of designing a USB bus powered audio product around 2.5W for professional/consumer use. The product enclosure will be UL94 5VA flammability rated plastic. Will this product have to be NRTL approved for sale in the USA/Canada? The EU LVD doesn't apply
