Hello from Dayton the source of Aviation the Wright Bros.
Computer and Business Equipment Manufacturers Association
is what CBEMA stands for in historic literature.
This name has been changed to Information Technology Industry
Council. ITIC Technical Committee 3, of which Rich Nute is a
member, sponsored the development and publication of the
tolerance curves for sag and drop out.
The name was changed because of the widening technology
going beyond computers and business equipment. Also, many
suppliers are no longer specifically manufacturers in the real
sense of the word. ITIC is more comprehensive of the actual
membership in the organization.
TC3, Technical Committee 3, is the Power Interface committee
at ITI. The New Chair is John Wagner of Lucent Technologies
in Denver, Colorado. Due to the changing nature of technology
of the power interface, this curve has just been revised by ITI,
with the help of the Electrical Power Research Institute.
Your question is quite timely, in that there is a debate as to
what the name of this curve should be, since CBEMA has a
name change to ITIC. Due to its history of reference as the
CBEMA Curve, some think this should remain the name, but
since ITIC is the sponsor, some think it should be changed.
As to a new name for the curve, we will have to wait and see.
If anyone has a suggestion they can send it to John Wager
at Lucent. E-Mail: john.wag...@lucent.com.

Subject: CBEMA Curve and IEEE 446 Orange Book
Quick quiz time: What does CBEMA stand for on the voltage sag and
drop-out
curves, such as in the IEEE 446 orange book and other places?
Someone here at work asked me, and I'm stumped!
thanks!
