Just the other day, I looked at
the back of a power supply we use and found no less than eleven, yes, eleven
certification marks printed in tiny little letters on the back. Confused, I looked up a few of them only to
find out they were certifying the same thing, just for different
countries. Who would ever have known
that a 12 VDC, 1.5A output power supply could be so different to so many
different people? “PSE” for Japan, “UL”
for the USA, “CUL” for Canada, “TUV” for Europe and the list goes on and on, and
on again.
It is not just Power Supplies, my
lawn mower clearly says not for use in California or Australia presumably
because the certification requirements there are different. Try buying a car in Europe and importing it
to the USA. You will need waivers and
approvals and exemptions because their safety rules are different from
ours. Perhaps their asphalt is different
or the sun is brighter or, the available steel to make guard rails is a little
more brittle, but who knows, why something required in one country is not good
enough for another.
In 2011 I was invited to Germany
to discuss new standards for R-1234yf. I
came loaded with previous experience, examples, data and informed
opinions. I left there bewildered at the
response to my presentation and wondering what the group I met with was
thinking. Was it a language
barrier? Was it my attitude? How about an outside influence that presented
before me, could that be it? To this
day, I can only surmise that I was viewed as the pompous American before I had
even walked in the door and if I said the grass was green and the sky blue they
would insist it was the opposite. But I
digress. After multiple visits to Europe
and numerous prototypes designed to meet the letter of their requirements, we
had our European certification despite the flaws in the specification and the
challenges posed by it in the real world.
Then came the SAE where I was in more familiar territory and a
significantly more receptive audience to the same previous experience, examples,
data and informed opinions. In this
group, a standard was formed that required the development of a practical tool for
use in the real world. So today we sit
with different standards for AC Service Machines, Refrigerant Analysis and Leak
Detection between Europe and the USA.
Different components, different software, different servicing and
maintenance and last but certainly not least, higher cost for all.
