This really brightened up my day, especially number 7. It's good to see a
sense of humor in this, sometimes, very serious forum.
By the way, I totally agree with you - Directors and above cannot be
trusted. I once worked for one who wanted to understand the product safety
process so he
I've looked into this in the past, and there appears to be no
legislation. There is a guide to appropriate wording in BS 1133
section 21:1991 but, frankly, this falls far short of a useable
specification for safety markings on bags. Most retailers also want
to see perforations, and some
I've used the approach that one doesn't design compliance IN, one designs
non-compliance OUT. People who have the view that EMI reduction is a matter
of filters, shields and spring fingers, find out, if they don't know
already, that this is the expensive way to do things. They become more
The last thing you want to do as a compliance engineer
under such circumstances is to appear as something of
a Compliance Cop. This will drive an impenetrable
wedge between you and literally anyone in management.
Most probably what James says is correct - the director

I am in the process of reviewing the plastic bags we use to package our

Pierre,
Various engineers within a test house evaluate products differently due to
their own interpretations. The 60601 series of standards have not been
designed to accomodate the high voltages occuring within switching power
supplies. The standards are currently being worked on to incorporate

I didn't post to group on that last reply, so I'm resending. I believe if
you are speaking of accreditations, NVLAP/NIST would be an equivalent.

Our UK office has inquired to us about NAMAS accreditation. I think possibly

If you want a UL Listing of this device, UL will be the one to determine
which standard. My guess is that most of the requirements would come from UL

Sam,
The key phrase is free-space wave impedance. At the source, the wave
impedance matches the impedance of the driving circuit. The electric
fields and magnetic fields interact (near-field conditions), working
toward the free-space wave impedance of about 377 ohms. The impedance

You may want to look at some of the polymer aluminum electrolytic

Not necessarily, you may want to cost reduce the product in the future

Hi Brian,
Go back and ask the customer what the requirement means. It is not
unusual for contracts to be written by people who do not have experience
in all matters pertaining to a specific contract. It appears that
sometimes they pick-up a phrase that sounds good but they do not
understand,
Scott, I always preferred to keep it simple.
Compliance is developing a product that complies with specific requirements
stated in applicable national or international standards developed by
recognized experts.
We comply with those standards because that is what our customer base expects

This is a topic that can be of great benefit to a lot of people.
I've had extensive experience communicating this topic to managers and execs
throughout my career, and there is a logical approach that I've adopted which
seems to work well.
First, there are three major components of any
I am not familiar with GR 1089, but assuming there are electric field
emission limits from 60 Hz to 30 MHz, the magnetic field limit would then be
the electric field limit minus the free space conversion factor. The
magnetic limit would be independent of the electric field emissions, it
depends

I've had this same problem over the years with many man hours spent looking
for why. We changed to 35 and 50 V parts to good effect in some cases.
Other cases were not so easy. I like Cortland's idea the problem is charge
current at turn-on. We had a 5 output 350 watt supply and there
