Transcript of information of the field direction over 360° - Babbco - … COMMAGNETIC TES… · ·...
� Pie Gauge ASME: useful
with a handle (rarely
lost), field direction on 6
areas.
QQ Shims A (aeronautical) or
G (general):
� Indicator Afnor N°2 : this indicator can be
used in fluo as in black and white (it is
already whitened), it provides an
information of the field direction over 360°
� BERTHOLD Gauge: also with
a handle, field direction on 4
areas, rotary part to value
the detection quality.
� Test tube ASTM
D96/D91 (tube/cone) or
D1966 (pear shaped) for
sedimentation volume
with its stand.
� MTU test piece
autonomous, for a
visual comparison
of the magnetic
developer’s quality.
� Flexible test piece with flexible
strips: takes the exact shape of the
part.
� 3 parallel lines “test piece“: 2
“hard“ fencing and 1 “easy“ to
detect (case of 5).
� Test piece A “test bar with holes”:
on bench, checking by field
current as per NFA-09-570.
� Test piece C EN ISO 9934-2
REFERENCE BLOCK TYPE 2
(ex NFA-09-570): autonomous
strips test piece for a magnetic
developer’s sensitivity
measurement.
� Test piece B “ladder-staped test bar“:
on bench, checking by flow
current as per NFA-09-570
� KETOS ring as per
ASME or DMC0070
SNECMA, detection
check on fixed bench
by current flow.
� Ring AS5282
