“Without measurement
there is no control,”
asserts the website
of Particle Measuring
Systems, a supplier of
equipment for monitor-
ing
and
qualifying
contaminants.
Just as plausibly might
the company serve
notice that there is
also no control without
inspection,
testing,
and marking. The four
stand or fall together,
with faulty execution of
any of them cancelling
out
excellence
in
the others.
Zero tolerance is very much a working ideal in the tube making operation, and
sound methods of inspection, measuring, testing, and marking are critical to
process control. These are the certification specialities, without which it would
be impossible for the manufacturer
to guarantee that product delivery
from the plant may be accepted
with confidence.
In statistics, an error is not a
‘mistake’
. In tube making it is.
The specialities under review
here ensure that, in the critical
transaction between producer and
customer, error has no part.
