Re: [PSES] EMC tests called up in Safety standards

Pete Perkins said: "Historically, the HV impulse tests applied are safety tests." Safety-wise, HV tests of safeguard insulations are to determine that the safeguard insulations will withstand the normally-occurring transient voltages that occur on the mains circuits. I wouldn't call

Further to Scott’s post, the required illumination is at 20V/m at the EUT, rather than the more commonly used 10 V/m (I don’t know the 60335-1 requirement). As Scott mentions, the intent in this case is to make certain the inverter remains functional, less so that it remain in a safe condition

Re: [PSES] EMC tests called up in Safety standards

If I remember correctly, the text in 60335 was prompted by an incident in Denmark where a toaster incorrectly switched on due to EMI. Since the work was done under pressure, it might not have been done in the most appropriate way, but the end-result is as intended. John Woodgate OOO-Own

Re: [PSES] EMC tests called up in Safety standards

The EMC tests as called out in 60335  are safety tests, contrary to those called out under the EMCD that are functional tests only. For Europe , one can discuss about the necessity of those tests, as the EMCD  requires testing in all operating modes including OFF or standby and  as long as one

Re: [PSES] EMC tests called up in Safety standards

One would normally expect immunity to be covered in a product-family performance standard applying to the whole family, which would be a TC59 publication in this case. But such a standard does not exist; however there is a product-family safety standard applying to the whole family, which is

[PSES] EMC tests called up in Safety standards

Hello experts, I note that EN 60335-1 (household and similar appliances) specifically calls up EMC immunity tests in clause 19.11.4 where the controls for the EUT are set in the "off position" and a set of immunity tests are applied. For something that controls a heating element, I can see why
