"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

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.

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

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

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
