DESCRIPTION AND OPERATION
Description and Operation
Device Function
Regula 7505M is designed
for non-destructive investigation of metal surface and for
document examination to control their authenticity and detect falsification of VINs and vehicle
documents .
The device is a set of hardware and software products enabling visualization (video imaging)
of the relief and structural inhomogeneity of the metal surface with magnetic properties
(traces of mechanical processing, inclusion of non-ferromagnetic materials, surface flaws of
welding seams), without removing the lacquer-and-paint coating (if applicable) by methods of
magneto-optical visualization . A PC is used for capturing, collecting, processing, transferring
and displaying information .
The device is intended for use by forensic laboratories, law enforcement agencies, judicial
authorities, customs and insurance companies . As Regula 7505M provides high-quality
results, uses non-destructive methods, operative and obvious character of magneto-optical
investigations, it can be used for express inspection (e .g . at customs or by highway patrol),
as well as for advanced forensic examination of vehicle VINs in laboratory conditions . In case
any VIN changes are detected, further investigations can be carried out using a special set of
peripheral hardware tools (supplied optionally) suitable for a case .
Application
Objects of control are divided into two categories:
Category
“A”
—
vehicle unit surface (data carrier –
body, engine and chassis) with relief
identification
number
applied
by
mechanical processing, electro sparking
or laser mode .
Data carriers of integral body frame
in mass production passenger cars are
normally made of sheet steel: RRST 1405
(DIN 1623 quality standard) cold rolled
sheet steel; UST 1203, UST 1303 unkilled
sheet steel . Exceptions are made for
Audi A8/S8 series bodies, produced
since February 1994, because their body
panels are made of aluminum alloys
Engine cylinder blocks are mostly made
of special cast iron and aluminum alloys .
Thickness of non-magnetic coating
(galvanic and lacquer-and-paint coating)
of manufactured vehicle body parts
is 185 μm (with 6 layer coating); but
typically it is 40-80 μm .
Category
“B”
—
materials and printing methods of vehicle
related documents .
Device components enable to examine vehicle
related documents security features activated in
different spectral ranges (absorption, reflection,
luminescence) when they are viewed under lights
with different wavelengths (for more information
see Spectral Luminescent Magnifier Regula 4177

) .
