REMARKS:
Calibration
of reference microphones 4160 serial numbers
991820,991821,1054926, and
standard pistonphones 4220
serial numbers 1048473, 1048795, 1510240 and 4228
serial
#1793011 and 4220 with 40 ccm volume serial #
1048747 are calibrated traceable to NIST
with NIST
Test number 822/261669-99.
NOTE: The
verification/calibration listed on page 1 of this
document was performed on
a test system which
conforms to and operates under the requirements of
ANSI/NCSL Z540-1
which also covers the
requirements for MIL STD 45662A.
