Hi Ken,
With short delay, Thank you.
So on short, if flexible cord is used, cord must have a plug, if wiring
terminals are used, cord must be put in conduits.
Do you know the background of this requirement? Is this applicable even if unit
is used in a computer room with raised floor?

UL will generally accept a Class 1 air filter. These are evaluated against UL
900.
Otherwise, it depends on the standard for the end product what requirement
apply. I recall 60950-1 accepting HF-1.

EN61581-22 is listed in OJ under LVD. But the standard also includes EMC
requirements. But will those EMC test justify EMC for fulfilling CE? I doubt
that.
An harmonized EMC standard in addition, would give a combination of LVD and
EMC standards for fulfilling CE
If you are taking relative measurements of a single spur then this device
might work just fine...

Hi Brian:
I have only a passing familiarity with the type of requirements that you are
asking about, but I can offer a few tidbits.
For telecom carrier equipment, requirement GR-63-CORE (2012) requires a
filter on all fan-cooled equipment, and contains requirements for the
filtering

>From "memory" of 60950 and the like, in view of the testing you have already
done, and because the filter is outside the fire enclosure, then, for Q1, an
HBF ("Horizontal Burning, Foam" IIRC) rating should be "adequate" to meet
the standard in the same way that a piece of external solid
Most PCs don't blow air in, they blow it out, and the air inlet is well away
from the power supply block. This tends to blow dust *out* of the innards
and seems to work well, without the use of a filter. Of course, I don't know
whether you can do that with your product.

I seek advice and opinions from fellow safety minded people.
Our typical product has a metal chassis which is constructed as a Fire
Enclosure (laboratory equipment 61010-1). On the back is a cutout for a cooling
fan/blower mounted in the cutout. The fan is 24Vdc, certified by several safety

Any spectrum analyzer can measure any level, with appropriate

Will this USB spectrum do the job? Any experience about this unit?

Measure output RF level at 2.4GHz and 3rd harmonic is important.
Frequency accuracy aswell.
Thanks!

Hello,
I think you're possibly correct, but I also see that happening regularly
with the attempts to squeeze more users into the finite amount of spectrum.
A long time ago now, the decision was made that "effective use of spectrum"
in the EU RED would mean that all radios have receiver
Who decides if a given technology makes 'efficient use'? For example, simple
AM could be disallowed because it's not as 'efficient use' as 16-OFDM.
I am concerned because a certain novel technique may quite possibly be
unusable in Europe because of this 'efficiency' provision.
