DEFINITIONS
1.2.1
A Scan
Method of data presentation on a cathode ray tube using rectangular
coordinates in which a horizontal base line indicates elapsed time when
reading from left to right. A vertical deflection in the base line
indicates reflect signal amplitude.
1.2.2
Acoustically Similar Material
Material the same as that to be inspected; or
another material
proven to
have acoustical velocity within plus or minus
3 percent and an
within plus or minus 0.001 dB/mm 0.25 dB/inch
of the inspected
material for
the inspection frequency and wave mode, using
the same mode as
that to be
used for inspection.
