So I suppose when the next leap of speed is made in the design and/or operation
of reverberant chambers, we can expect them to be marketed as Turbo Reverbs.
Add another improvement, and we'll be buying Turbo Surfer Reverbs. Excuse me

Hi all,
Our experience is that you get pretty much the same levels with either a
reverberation chamber, or with high gain antennas in a regular anechoic
chamber. It is possible to increase the antenna gain by 3 or 4 dB compared to
traditional methods, and get up to the same levels achieved in

Been a long time since I had a product for ITE safety to 60950-1. I know
there have been changes since my last effort.
The product is ITE and powered by an EPS at 12V DC, 24W. Normally I would
say safety is not required for the product, only for the EPS. But this

We occasionally do pre-tests with a setup where the tester is on a normal floor

There has been a debate as to whether this can effect results. If the tester
had picked up a charge, it would be present on the outside of his body and the

Debate is probably not useful. Do you see any inconsistencies in test

Colleagues,
The PSES will be holding a Product Safety Engineering Workshop in Vancouver,
BC, Canada in June, and I need your help.
I am designing a brochure / flyer for the event, and I am in desperate need of
some hi-resolution images of various kinds of product safety testing in
progress. I
I understand the argument but the logic runs out of room pretty quickly, in my
opinion, since there is also a chance for damage after shipping to the
customer, does one then send someone to the end user's location to run the test
again?

Hi Carl:
I suggest you take it up a notch with NRTL2. Take it up
the management chain at NRTL2. NRTL managers tend to be
more open to issues of added cost to their client,
especially where the value of the requirement is
questionable.
At the same time, the manager has some duty to support

Hello Rich,
This issue has been decided by the chief engineer for all USA medical labs
at NRTL2. The interesting part is that the staff safety engineers at NRTL2
appear to agree with me (including Sr engineers there). I'm told that it's

No need to repeat 100% dielectric strength testing for Japan PSE . You must
provide the importer test records showing test has been performed on 100%
production. The importer must retain these records for METI inspection.
