A. Use this procedure to do an inspection for surface cracks in aluminum parts.
B. This procedure uses an impedance plane display instrument.
C. Part 6, 51-00-00, Fig. 4 is an alternative inspection procedure.
2 Equipment
A. General
(1) Use inspection equipment that can be calibrated on the reference standard
as specified in paragraph 4.
(2) Refer to Part 1, 51-01-00, for data about the equipment manufacturers.
B. Instrument
(1) Use an eddy current instrument that:
(a) Has an impedance plane display.
(b) Operates at a frequency range of 50 kHz to 500 kHz.
(2)The instruments specified below were used to prepare this procedure.
(a) Phasec 1.1; Hocking Krautkramer.
(b) Nortec NDT-19e; Staveley Instruments.
(c) MIZ-22; Zetec, Inc.
2、探頭Probes
(1) Use a probe that:
(a) Operates at a frequency in the range of 50 kHz to 500 kHz.
(b) Has the configuration shown in Detail I.
(C) Can satisfactorily do the angularity check as shown in Detail II.
(d)Can satisfactorily do the probe shield test of Detail III. This is necessary
if the inspection area is near adjacent structure to make sure the adjacent structure
will not change the signals.
NOTE: Shielded probes are recommended.
3、試塊Reference Standards
(1) Use reference standards 126, 188A, 189 or NDT1048. See Details IV thru VII
for data about the reference standards.
(2) Other reference standards can be used if they are equivalent to those shown
in Detail IV thru VII.
E. 輔助工具Special Tools
(1) Use a nonconductive circle template as shown in Detail IX to help examine
near the edges of parts for cracks.
(2) Use a nonconductive straightedge as shown in Details X and XI to help examine
the area around flush head fasteners for cracks.
NOTE: The circle template and straightedge help to keep the probe a constant
distance from a fastener head or structural edge. The signal will slowly increase
when the probe gets closer to an edge of a part.
三、檢查準(zhǔn)備Preparation for Inspection
A. Get access to the inspection area.
B. Remove loose paint, dirt and sealant from the surface of the inspection area.
