Group,
I would like to get some input on how 60950-1 people and others deal
with 60950-1 2.10.5.4 Semiconductor devices: optoisolators
We are dealing with the issue of option a) vs option b) to show
compliance.
The end goal is to identify that the component satisfies the following,

We have a low voltage camera (class 3) that appears to NOT legally
require a NRTL certification for National Electric Code acceptance.
The product is powered by a LPS and should therefore be out of the
jurisdiction of the LVD also.
However, the camera also houses an IR light

Can anyone inform me if there are “National Deviations” to the CB scheme
for South Africa?
Our customer is asking for a CB report, and I see that SA is a CB member, but
I don’t have any list

Group,
We have some indirect evidence, and some damaged product, that appears to be
related to over voltage on the power grid in Australia.
The nominal is 240V 50Hz, but we are hearing accounts of voltages as high as
285V.
Has anyone else had to deal with damaged product, or can confirm that
Hello group,
I have been able to find limits for noise exposure, but not measurement
methods. Can anyone give the measurement methods, or a reference to a
method. Specifically, I'm looking for something like the distance from the
microphone, to the noise source.
Thank you

Dwight,
Our engineering group regularly sends products out for HALT testing. We
design ITE, although not computers. Some of the system problems that they
uncover are broken solder joints (mass of component), poor connections
(circuit boards), and other mechanical problem (fasteners).
The main
Just to offer another idea.
These recorders work great in the car. Taking a note on paper can be quite a
hazard while your driving along. I've used one for about a year now, and
it's helped me remember lots of ideas, and tasks to jog down later.

Hello group,
I have a vendor that wants to sell us line cords for use in Europe. There
are several agency marks on the cordage, but no HAR. The plugs have
several agency approvals.
Does anyone know the legal requirement for marking the cordage.
I have seen references to HD-21 and HD-22, but do
Does anyone have knowledge of VDE 0884, 'optocouplers', and why it is
more difficult to get approval to than UL1577 Optical Isolators?
Particularly, the Dielectric withstand voltage required, and something
about charge transfer between the emitter and detector.
Thank you

In an effort to be as compliant as possible, the following concern has
been raised
by one of our technical writers.
I know I have seen information on this in the past, but need a
refresher.
Does anyone have details on when a warning or caution should, and should
not be used?
