IF THERE IS NO EXTERNAL SOURCE OF MAGNETIZATION
FOR THE EXAMINED OBJECT, THE USE OF AN ATTACHMENT
(POS . 7 OR 8) IS OBLIGATORY .
Means of measurement, tools and accessories
Magneto-optical device Regula 7505M (used in composition
with ECMD) belongs to the category of displaying(not measuring)
devices . Therefore, means of operation control of Regula 7505M and
ECMD as its component are produced as test-objects, simulating
widespread modified changes of VINs (pouring by polymers, pressing
in fragments, and removal of the metal superficial layer). The control
order of device serviceability with the use of the test-objects is
described in detail in paragraph 2 .1 .3 . of Regula 7505M OM and 3 .3
of the given OM .
Characteristics of the test-object of the device:
Test-object №1 (Al) (Fig. 6) is the imitator of Category “A” control
object (the data carrier of the vehicle body). It is executed in the form
of a plate made of a sheet of aluminum alloy 1 mm thick. The initial
number 20165 is applied by machining process (cold pressing).
The initial number was made in the following way: manual stamping
using “№10 type” markers kit and hammer on a massive anvil.
The depth of digits
relief makes about 0 .3-0 .4 mm .
Three digits
of the initial number were modified as follows: “0” for
“9”, “6” for
“9” and “5” for
“7” . Thus, the altered number appears as
“29197”
(the altered digits
are underlined) .
Digit
“0”
in the initial
number was altered manually using
cold calking
of the element (bulkhead) of digit
“9” with the help
of a bench tool and then stamping of the new digit
“9” over
the remaining contour of digit
“0” .
Digit
“6”
in the initial
number was altered in the following way:
dismantling (cutting-out) of the initial
number fragment bearing digit
“6” with the help of a blanking tool, swap (180° rotation),
pressing
in
of the cut-out fragment with digit
“6” (thus digit
“6” is transformed
into digit
“9”
) .
Digit
“5”
in the initial
number was altered manually using
the process of pouring of the digit relief by polymer (epoxy spackling);
stamping of the new digit “7” over soft spackling .
After the digits
of the initial
number were modified, the following
operations were executed on the test-object: scraping; spackling;
