� 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
