offering decisive advantages over
conventional application
techniques in many areas of
industry including penetrant
testing.
Due to the electrostatic charge
the penetrant (developer) particles

extremely fine atomization. The
uniform spray jet generates a very
homogeneous material application
with an even coating, resulting in a
particularly high quality finish.
The wrap-around effect results
from a force field between the negatively charged penetrant To achieve maximum wrap-around and optimum

 TEST PANELS

Sensitivity of inspection media, quality of intermediate cleaning and control of the whole penetrant process are determined by
test bodies, which are metal panels with defined roughness, provided with standardized artificial cracks (defects).

Test body JIS Z 2343

Art.No. 127.600.001 - 10 μm
Art.No. 127.600.002 - 20 μm
Art.No. 127.600.003 - 30 μm
Art.No. 127.600.004 - 50 μm

The test body is used to determine the sensitivity of penetrant systems and for comparing
two penetrants, one of which can be taken for standard. It consists of two test panels which
are bronze planes 100352 mm, plated with NiCr-layer. Several crosscut cracks are made
in the nickel-chrome-plating, the depth of cracks fits the width of the NiCr-plating. The
bodies are designed in 4 types – with plating width of 10, 20, 30 & 50 μm. The quotient of
cracks’ width to their depth equals 1:20. Each test-panel is provided with a certificate
according to EN 10204, type 3.1 B, which verifies its conformity to EN ISO 3452-3. The test
panels with cracks’ depth of 10, 20, 30 μm are used for testing of fluorescent penetrant
systems sensitivity. The sensitivity of contrast penetrant systems is determined by panels
with cracks depth of 30 and 50 μm.

Reference Block No.1 (EN ISO 3452-3)

Art.No. 127.400.001

The Type 1 Reference Block for testing sensitivity of fluorescent and visible penetrant
systems consists of 4 nickel-chrome plated panels with 10, 20, 30 and 50 m thickness of
plating respectively.
The panels with cracks’ depth of 10, 20 and 30 m are used for determination of the
sensitivity of fluorescent penetrant systems.
The sensitivity of visible (contrast) penetrant systems is determined by using the 30 and 50
m plated panels.
The Type 1 panels are rectangular in shape with typical dimensions of 35 x 100 x 2 mm
Transverse cracks are made in each panel by stretching the panels in the longitudinal
direction. The width to depth ratio of each crack should be approximately 1:20.
A declaration stating conformance to EN ISO 3452-3 and in line with EN 10204, Type 3.1 B
shall accompany each test block.

Reference Test Panel No.2 (EN ISO 3452-3)

Art.No. 127.550.000

The Reference Test Panel No. 2 is an austenitic plate, which is chrome-plated and provided
with four fields (25 x 35 mm) of different surface roughness (Ra = 2,5 m, Ra = 5 m, Ra
= 10 m and Ra = 15 m) on the one half and 5 star-shaped crack patterns of different
sizes on the other half. The rough fields are used for control of the intermediate washing-
off. The star-shaped cracks in the chrome plating are generated by ball stamping from the
rear side.
The indication on the reference test panel gives no suggestion of the indication on the part
under test.

Test Panel ASME V

Art.No. 127.100.000

The ASME V panel is used for the testing of the penetrants indication sensitivity. Due to the
division of the test panel into two parts, it is possible to compare two different penetrants.
The test panel is an aluminum block of 80  50  10 mm, divided by a notch
(50  2  1,5 mm), into two parts. Because of a special thermal treatment the panel
surface is provided with a crack pattern, which is different on the front and rear side of the
test panel.

The Test Panels are designed to evaluate the removability of fluorescent penetrants
according to the requirements of AMS 2644C.
The WTP-1 is a stainless steel panel, measuring 4×6 inches with two parallel “medium
rough” strips, each 6×1,5” inches, separated by a smooth 1 inch strip.
The WTP-2 is a set of two identical panels measuring 1.5 x 2 inches produced from a single
sheet and is also used for assessment of fluorescent penetrants removability.

Test Panel PSM-5

Art.No. 127.800.000

The PSM-5 test panel is used for testing the penetrant process in whole while human or
automatic (semiautomatic) processing according to Pratt & Whitney Aircraft TAM 1460 40.
The PSM-5 is a rectangular panel, measuring 1015 cm, width 2,3 mm, made of stainless
steel.
The chromium-plated strip on the left side contains 5 star-shaped crack patterns which are
arranged according to their sizes. The crack pattern differs from one panel to another. The
right half is sandblasted and used to evaluate the penetrant removability.
The panel should not to be used for comparison of different penetrant systems.

UTE-3 Inspectability Scale & Visual Comparator

Art.No. 127.850.000

The INSPECTABILITY SCALE is used under UV (black) light to determine if fluorescent

brightness at the test surface is adequate and in proper contrast to ambient white light. It
also can disclose whether the operator can see the size indication he is seeking.
The VISUAL COMPARATOR consists of sentences printed in Jaeger 1 and Jaeger 2 print
sizes. The operator’s ability to read the appropriate sentence (J1 or J2 as required by the
applicable specification) at the test surface, determines his visual ability under the test
lightning conditions.

The magnetic particle testing is a separate processing procedure which consists of following parts: 1. Preparation of the test
objects’ surfaces for testing; 2. Magnetization of the object; 3. Application of magnetic particle suspension (powder) onto the
test object; 4. Inspection; 5. Demagnetization.

Circular, longitudinal or combined magnetization are used for the magnetic particle testing. There are a lot of magnetization
schemes, some of which are shown below.

ZER-O-MAT MAGNETIZING AND REPAIR STATION

ZER-O-MAT® devices are magnetizing and inspection

stations designed for the magnetic particle inspection of
pipes, rods, bars and other tubular parts with the diameter
from 20 up to 660 mm. The devices enable the user to find
surface flaws of multidirectional orientation in one operation
within shortest time. The use of these devices is not limited
to round shaped products. They can be also applied for the
inspection of stocks and bars with square, rectangular or
even irregular shape. Furthermore the ZER-O-MAT® stations
are perfectly appropriate for pipe-end testing.
Besides the use for local inspection at repair stations, the
devices can also be used for full length inspection of tubular
products, and in both cases an immediate repair, i.e.
directly after the (re-)inspection, is possible.
Essential part of the device is the ZER-O-MAT® solenoid
coil, developed and patented by Helling GmbH. This coil has
a characteristic U-shape, so that products to be inspected
can be ”dipped” into the coil from above. The non-contact
magnetization with the coil prevents burns on the tube
surface and enables to detect surface flaws of
multidirectional orientation within shortest time. The
tangential field strength is min. 24 A/cm. ZER-O-MAT®-
coils are operated with AC-current. This means that due to
the skin-effect just a surface layer of the material is being
magnetized. Therefore no demagnetization is necessary
after inspection.
For magnetization and inspection the tube is getting turned.
The showering with a magnetic particle suspension goes on
at the coil bottom (04.00 – 08.00h-position). The
indications can be observed and evaluated in the turning-

 REFERENCE BLOCKS AND FIELD INDICATORS

Reference and test blocks are used for the quality analysis of the magnetic particle suspensions as well as for the estimation of MT
overall performance.

Reference Block No.1 (DIN EN ISO 9934-2)

Art.No. 134.002.002

The reference block No.1 is a disc with 2 types of natural cracks on the surface.
Coarse cracks are the result of the polishing, fine cracks are the result of stress
corrosion. The block is permanently magnetized by central conductor through the
hole. Estimation of magnetic particle suspensions is made by visual or other
appropriated method of comparison of the indications.

Specifications:
Sample diameter: 50 mm
Sample height: 10 mm
Cracks width: 2-10 μm

Reference Block No.2 (DIN EN ISO 9934-2)

Art.No. 134.002.100

Reference block No. 2 is a self contained unit requiring no external magnetic field
induction. It is used to determine the quality of the magnetic particle suspensions.
The block consists of 2 soft iron bars, separated by a thin (15μm) Al-foil,
representing an artificial defect. Permanent magnets are set on the sample ends.
Because of the permanent magnetic field the bars get magnetized and magnetic
particles accumulate over the artificial defect, forming the indication lines. The
quality of the suspension or dry powder is estimated over the summarized length of
the lines.

Specifications:
Dimensions (LWH): 1554012 mm
Tangential component of magnetic field
over the artificial defect at points G (-4): -1/ m
(4): 1/cm

Berthold Magnetic Field Indicator (Penetrameter)

Art.No. 134.003.000

The Berthold indicator is designed to determine the strength and direction of the
selected magnetizing setup and the quality of fluorescent magnetic powder
suspension.
When placed on a magnetized test piece, magnetic lines pass through the sectioned
iron cylinder. The cuts on the iron cylinder will be visible when magnetic powder or
fluorescent magnetic solution is applied. Maximum indication direction is achieved by
rotating the sample about it’s axis. The field direction is perpendicular to the flaw at
maximum indication. Magnetizing efficiency, penetration and quality of the
fluorescent oil suspension can be determined by slowly turning the outside ring of
the field indicator, increasing the distance between the thin brass plate and the test
piece. The amount of lift-off at the point where the indication just appears gives a
measure of magnetic field test efficiency.
Specifications:
Sample diameter: 20 mm
Sample height: 5 mm
Holder length: 95 mm
Weight: 24 g

D 250 Magnetic Field Indicator (ASME Indicator)

Art.No. 134.003.100

The ASME indicator is used for localization of magnetic fields and their directions
during performance of magnetic particle testing.
Suitable magnetic flux is obtained when the indicator is laid copper side up on the
work piece in the area of interest and a clearly defined indication is formed across its
face when magnetic particle suspension is applied.
The magnetic field indicator type D 250 is designed in accordance with the following
specifications:
MIL-STD-271 E, § 4.3.2.5.5, figure 8
NAVSHIPS 250-1500-1, § 12.4.1.5, figure 12 – 17
ASME, section V, Art. 25, SA-275, figure 8
Specifications:
Sample diameter: 27 mm
Sample height: 4 mm
Holder length: 100 mm
Weight: 42 g

Burmah-Castrol Magnetic Flux Indicators

Art.No. 134.002.110 - Typ I

Art.No. 134.002.120 - Typ II

Burmah-Castrol strips are widely used to indicate the presence of induced magnetic
fields giving an evidence of an external field in the air above the magnetized surface.
Type I indicators are typically used for general engineering applications and Type II
are used for aerospace applications. Both types consist of three laminations
measuring 50x12 mm which are fixed together to form a sandwich structure which is
nominally 0.15 mm thick. The outer lamination has 3 interruptions which are parallel
to the long side. Type I indicators respond to a weaker field than Type II strips. Both
types are protected by a polymeric layer and can be differentiated by the Roman
numeral.
Flux Indicators have the advantage of being flexible enough so that they can be bent
to fit the contours of a work piece, but robust enough to enable them to be used
many times.

Ketos Ring (ASTM E 1444-01)

Art.No. 134.004.000

Ketos ring is made of AISI 01 tool steel, hardness 90 to 95 HRB. It is a magnetic

field indicator, but in reality determines the efficiency of the complete MP testing
procedure. The sample is a 22 mm thick ring (‡ 127 mm) containing 12 holes
(‡ 1.75 mm) drilled at different distance from the ring edge.
The magnetizing current passes through the center of the ring via a central
conductor and the leakage fields appear, decreasing as the distance from the hole to
the ring edge increases. When the magnetic suspension is applied on the ring,
magnetic powder accumulates on the ring edge over the cylindrical holes, forming
indication lines.
The process corresponding to the recovery of recommended number of holes is
accepted as optimal.

 Duplex Image Quality Indicator acc. to DIN – EN462-5

rt.No. 220.049.400
The duplex image quality indicator is used for measuring image unsharpness. It is a
particularly useful tool for establishing and monitoring the performance of
radioscopic (real-time) systems. The indicator consists of 13 platinum or tungsten
wire pairs of different diameters embedded in rigid plastic. The wires spacing in each
pair corresponds exactly to its wires diameter. The degree of unsharpness is
indicated by the number of wire pairs that can be seen. As unsharpness increases,
the wires merge to form a single image.

 IntBond 2000 System for testing of multi-layered structures bonding

The IntBond 2000 system is designed for testing of multi-layered structures bond
quality.
Ultrasonic resonance spectroscopy (URS) utilizes information in the frequency
domain obtained due to the constructive and destructive interference of elastic
waves for nondestructive evaluation of inspected objects. In a resonance test an
ultrasonic tone-burst with sweeping frequency is applied to an ultrasonic transducer
and a resonance spectrum of the inspected structure is acquired. The acquired
spectrum contains information about the properties of materials used for the
structure and flaws that may be present in it.
Narrowband ultrasonic spectroscopy can be used for the NDT of aerospace multi-
layered structures. The INT-Bond-Tester is used for this test operate on the principle
of exciting a mechanical resonance in a multi-layered structure. A piezoelectric
probe, excited by a swept frequency signal is coupled to the surface of the inspected
structure using a coupling agent. The instrument acquires probe’s frequency
spectrum in the range of some tens of kHz to several hundreds of kHz. A resonance
in the layered structure occurs when echoes between two boundaries travel back and
forth due to the difference in acoustic impedances at the boundaries.

The portable X-Loupe microscope camera is irreplaceable for precise, fast and
traceable documentation. This is a modified Canon IXUS camera with attachable
battery module and three interchangeable lenses – of 60x, 100x and 150x
magnification.
The lenses incorporate an adjustable LED light. This feature solves the most
challenging illumination problems when taking micro photography. The X-Loupe is
completely independent of all exterior light sources and can be used under any light
conditions.
Moreover the microscope camera can be combined with an UV lens, which enables
defects estimation and further documentation under UV light.
The X-Loupe captures images of objects in the range from 15 mm to 0,005mm,
making it possible to identify microscopic details that need attention, and via image
management software making them available to customer within minutes. The
software enables to transmit high definition images where observations, comments
as well as measurements are included within the image. So the microscope camera
makes it possible not only to get high resolution pictures but also to estimate defect
geometry.
The image can then be sent as a JPEG file or as a detailed Excel spreadsheet.
