Searching for an old standard

ADC 1062
"Test Code for Grilles Registers and Diffusers"; Now obsolete, this was one of the
original standards dealing with testing and certifying registers, diffusers, dampers,
and terminals. Originally developed in 1962 and encompassing boxes and grilles at
one time (but never fan powered boxes), several revisions were released through a
standard labeled GRD-1984. Tests included pressures, throw, velocity, and sound
under isothermal conditions. Also included was a cooling test to correlate
isothermal throw with room conditions as a room velocity. It told how to set up, take
readings, and determine the number of readings and sizes to test, analyze,
interpolate and report.
The Standard required the use of the Anemotherm Air Meter for
measurement of room air speeds and throw values. This meter has been reported
to be very slow to respond, highly directional, and subject to high error at low air
speeds. Throws measured with the instrument required by this standard may be
shorter than those reported using faster response, more accurate omnidirectional
air speed meters.
The ADC 1062 Test Code has been supplanted by ASHRAE, ARI, ANSI and
ISO procedures. At present, there are no ADC certified products or certified
laboratories in the United States, and this standard should not be referenced in
specifications. The ADC, however, is still active in certifying flexible duct.
CAD Impacts: This Standard should not be referenced in specifications for CAD
devices, although it often is. It never covered fan powered VAV terminals, yields
different results from the current box testing standards, and may yield short throws
for air diffusers.

(the student who asked the question) : Thank you very much, I have ASHRAE 70-1991 and ISO atandard for this purpose but I thought that ADC standard besides its old consumptions might be more helpful specially because it explains details of measurment, analyse and report.

Most of the standards associated with testing, adjusting and balancing of air distribution systems will be published by AABC, SMACNA, NEBB or ACGIH (at least in the US). If you have access to IHS, you can do a search on AIR BALANCE, but most of the industry groups will require you to purchase their standards if you are a non member, but most have student discounts available.
