CISPR 35 has not been published. The FDIS for CISPR 35 is presently out for
translation into French. Once that happens it will go out for vote by the
national committees. With luck it will pass this time. The Koreans jumped
the gun and based KN 35 on a version that was not accepted.

Hello All
I received a notice that starting in 2016, Korea will only accept test reports
to KN32 and KN35.
I assume that these are the equivalents of CISPR 32/EN 55032 and CISPR
35/EN55035.

I assume the relay would have to meet double/reinforced open contact
spacing and dielectric strength in this application. Correct?
Sounds right
We are having a hard time finding a relay that specifies an open contact
dielectric strength for double/reinforced (3000Vac or 4200Vdc).
How about t
Scott,
The relay we are looking to use is an Omron G7L series. It has a mechanical
life expectancy of 5 million operations and 100,000 electrical operations.
We also use a SSR for control so the safety relay is never opened or closed
while under load.

We don't have to worry about burns. This is an oven and proper tools and PPE
must be used or worn. The hazard of concern is with shock. The heating elements
cannot be guarded or insulated without affecting function. The only practical
way is to interlock the door and provide a proper Dis
This issue is half insulation/ accessibilty and reliability. Since you are
going to use the relay in a safety interlock circuit it needs to be certified
for a specific number of actuations.
The failure mode for a relay is closed, welded, and in your avg everyday
commercial model this occurs in
Are you trying to protect against shock hazard or burn hazard or both? Can you
eliminate the shock hazard with additional insulation or localized guarding?
If the user potentially has direct access to hazardous voltages you probably
have a very high PLr and need redundant contactors.

That would be my reaction as well - which is why I would expect AV
specialists to question its application to their kit, and why the 62368-1
Scope needs clarification.

I think EN 60905-22 is overkill for occasional use outdoors.

Good evening
I had the same idea as Ken re 60950-22 - and then got to thinking about
62368-1 which is replacing both 60065 & 60950, and the likelihood of a
"Part XX" to that standard.?
Did a quick search on "62368 outdoor equipment" and no "Part XX" was flagged
up, but amongst the results
Hello Scott,
There are many products that are commonly used outdoors yet are not tested to
any specific standard for outdoor use. Cell phones and tablet computers are
just two examples of such devices. It is not uncommon for the manufacturer to
specify the ingress protection (IP) rating under I
Hi Ken,
Thanks for your suggestion on 60950-22. I did not know or have this standard
but had some search on internet and note that the standard is for equipment
intended for outdoors. I doubt it is too tough for my said equipment. That is
reason why I believe there may be different levels fo
We have an application where during normal operation the user has access to a
30 amp heating element driven by AC mains. We will interlock a door which will
drive a relay or contactor which will open both sides of the AC mains going to
the heating element to make it safe.
I assume the relay wou
Hi Scott, I don't have any experience in this area but have you looked at

We are looking for a Level VI EPS that is 120 V~ input and 16 V~, 1.0 A

other is Level IV with the output cable stripped and tinned.
Has anyone had any luck finding Level VI efficient AC-AC wall mo
