As pointed out in the last paragraph -
providing uncertainty and
traceability is a method of MARKET SEGMENTATION.? You can charge
less
to people who don't really need it and charge additional to
those who
are required to have it.
I also was pleased with the fact that they provide the
reflection data.
It does not necessarily reflect on the quality of the work.
Cheers!

absolutely no extra charge. ?Allthey need to do is list the

? Of course they can.? But often, companies produce
reduced-cost
versions of products and services that omit certain features.?
In
the calibration industry, one of those features is
traceability
records. This is commonplace in the industry today, and is
nothing
new.
IF they are a legit Cal Lab all of
their equipment is calibrated,
some internally some externally and records are maintained.
?Theyuse the same equipment to ¡°cal¡± your equipment wether
they write a
cert. or not.
? Of course.? And most companies charge you extra to provide
the
serial numbers, calibration dates, and uncertainties of the
equipment used to perform the calibration with your
freshly-calibrated instrument.
If they don¡¯t supply a cert. as part
of the job find a new lab that does.
? Well, pretty much all of them do it this way.? This is not
new.
Running a cal facility REQUIRES that
you do certain things of you
don¡¯t you are not a cal lab
? Yes, but providing traceability records is not one of those
things. It should be, but it isn't.
? Another thing that happened in that world in the past not
huge
number of years is that "calibration" no longer means
"calibration",
it means "measurement".? Back in the good old days, when you
got
something calibrated, it got ADJUSTED if it needed it.? They
don't
do that anymore by default, unless you pay a whole lot more.
? I've gotten quite a bit of very good test equipment from a
local
biggish company because it "failed calibration".? When digging
around a bit with friends who work there, I found out that the
"calibration" service that they use, which is Tektronix,
doesn't
adjust anything. They merely measure it, and if it's out of
spec, it
has "failed calibration" and is returned with a red tag
stating
such.? This dumbass company has taken that to mean "it's
broken and
must therefore be thrown out", to the delight of the companies
from
whom they purchase test equipment.
? This is, as it should not be surprising to hear, an
engineering
company that has a lot more managers on staff than engineers.?
I
laugh at them regularly for BS like this.? Stupid suits.? A
lot of
really dumb things are done in this industry, and nearly all
of them
can be traced back to suits trying to wring money out of
clueless
management people. The story above is a prime example, but
calibration labs not providing traceability documentation if
you
don't actually need it really isn't.
? You see, a hobbyist or ham radio operator can send his Fluke
87 or
whatever in for calibration, and get it back with confidence
that
his/her measurements are good.? But would that person pay an
extra
couple hundred bucks for the stack of pages containing the
calibration traceability information?? No, because that
information
is of no value to that person.? The calibration company
doesn't save
any money by omitting it, but it does allow them to offer a
cheaper
service to people who don't need that documentation, while
avoiding
reducing their prices down too much on the services that their
bread
& butter customers require.
