4. ENSURING EXPLOSION-PROOFNESS OF THE PRODUCT.
4.1. Explosion-proofness of the product
Explosion-proofness of the device is provided by the type of
protection "intrinsically safe electric circuit" “ib” level, according to the
requirements of GOST 31610.11-2014 (IEC 60079-11:2011), which is
achieved by the following:
Basic circuit diagram includes the protective component “Fib”. The
protective component “Fib” is an intact spark protection unit with the
short-circuit current limitation at 1.85 A (maximum), using current limiting
resistors and semiconductor fuses in series. Double redundancy is used in
the “Fib” protective component to ensure greater reliability. The “Fib”
component is integrated into the battery compartment of the device. The
design of the protective component “Fib” is met with the requirements of
GOST 31610.11-2014 (IEC 60079-11:2011), including leakages and
clearances. The minimum width of conductors on the PCB is 0.2 mm,
copper thickness is not less than 18 µm. Thus, the electrical circuit coming
out of the battery compartment of the device is intrinsically safe.
The electrical circuit principal and applied third party components
provide maximum power consumption not more than 0.030 W from the
internal battery with maximum possible voltage on it Uo=3.6 V. The total
maximum capacity of the electrical circuit is 10 μF, maximum inductance
is not more than 20 µGn. The maximum current in the circuit during
normal operation is not more than 7 mA.

Dynamometer “DDIM-2”
The device is powered by a special internal battery type ER18505
according to GOST 31610.11-2014 (IEC 60079-11:2011).
The maximum temperature of overheating of components and
connections in the circuit diagram during normal operation is 15 °C max.
Thus, the surface temperature of conductors and elements during operation
and at maximum operating temperature plus 50 ° C is not more than 65 °
C. Device enclosures are made with the degree of protection against
external influences not lower than IP54 according to GOST 14254-2015.
4.2. Measures to ensure and keep the device explosion-proofness
during the assembly, disassembly and repair of the device.
4.2.1 Measures to ensure explosion-proofness before the production
process:
- The elements used in the protective component of “Fib” are
subjected to an acceptance test:
- resistors are tested for their nominal resistance;
- the fuses are checked against the short-circuit current limit;
- Materials used for casting the protective component “Fib” are
subjected to an acceptance test according to the certificates presented.
4.2.2 Measures to ensure explosion-proofness during production:
- The protective component “Fib” with the installed battery is
subjected to an outgoing inspection:

Dynamometer “DDIM-2”
- the short-circuit current and open circuit voltage at the output of
the protective component are checked;
- visual inspection of the filling location is carried out in order to
confirm the absence of any foreign inclusions, bubbles, cracks or
stratification.
4.2.3 Measures to ensure explosion-proofness during operation:
- Check that the cover of the battery compartment and the
compartment itself (including the threaded connection) are free from
mechanical damage and corrosion. In case of corrosion or mechanical
damage, do not operate the device;
- meet the requirements specified by the “X”sign in the explosion
proof mark.
4.2.4 Measures to ensure explosion-proofness during repair:
- the device must be repaired only by the employees of the
manufacturer.
Repair by third parties or individuals is prohibited.
- the protective component “Fib” is not to be repaired. It is made
intact and must be replaced in case of failure. Repair of the “Fib”
component is not permitted.
- after repair, the device must be tested according to the test
procedure, with the “Fib” component tested for short-circuit current and
open-circuit voltage (together with the battery installed).
