Not trying to start any arguments here, but the total subjectivity of this
issue really drives me nuts and leaves so much for difference of opinion that
it in itself becomes a regulatory barrier should there be a disagreement.
Aircraft FEMCA's for example have fixed time requirements for

A question has been posed to me, with reference to ITE standards UL/EN 60950-1,
whether a label is required near the appliance outlet stating disconnect power
before servicing. The equipment is table top ITE, pluggable with a
detachable cord. I do think it is an appropriate instruction for
Dear Jim,
You probably mean near appliance inlet? I do not see a background for such
label. Special label is required for service engineer if you have more
connection to mains supply.
What kind of service activities are planed on the unit?

Agreed, labels are needed for multiple power sources on same product but have
not seen a need for label with single power source

Thanks for the replies. This product only has a single external power source,
so no label is required. (And yes, Boštjan, I meant appliance inlet, not
outlet).

I thought it was common in most safety standards to require such a warning
marking on panels with AC Mains hazard behind them. Something like this
statement from IEC/EN/UL 61010-1 for ISM equipment:
If the instructions for use state that an OPERATOR is permitted to gain
access, using a TOOL,
The requirements vary depending on the product type. To some extent, the
requirements for marking panels that enclose hazardous voltages depend on the
risk that the end user will remove the panel. It is reasonable to anticipate
that the end user would remove panels on industrial equipment.
I remember the old CRT TVs with labels on the rear for disconnecting power and
the panels had the power connection integrated so you couldn't take it off
without the power being disconnected. For all those homeowners moonlighting as
TV repairmen/aka tube swappers.

I used to see a common statement on consumer products that says, No User
Serviceable Parts Inside. I wonder what standard required that because it is
just a statement, not a warning. It should says something like, Hey, if this
is not working chances are you cannot fix it, so don't open it up
ANSI/UL 60065 has the key word CAUTION- and No User Serviceable Parts Inside
text with symbols to Dangerous voltages: risk of electric shock and
Important operating instructions.
Earlier UL 813 has a long paragraph of warning and cautions text or use the
above note and symbols.

Dear Experts,
I am doing a deep dive into ISM equipment requirements for the first time. I
*think* I see a difference in interpretation of ISM equipment between the US
and EU regulations.
US (FCC Part 18) seems to limit the ISM concept to equipment that essentially
uses radio frequency to do

Please take a look at 47 CFR 15.103 (c) regarding ISM exemption to part 15.
However, back in the day, when I did EMC, we never worried about part 15 or
part 18 because we always did IEC/EN 61326-1 and declared victory for the
world.
