If the relative error exceeds limit, perform correction of sensitivity coefficient and “dead time”
in accordance with the section 2.4. It is recommended to perform correction of sensitivity coefficient
using the range 10 to 100

, the “dead time” is fixed at 23
s and is not changed during
calibration.
5 ROUTINE REPAIRS
5.1 Routine repairs include restoration of damaged cables and connectors.
6 STORAGE
6.1 Prior to putting into operation detectors shall be stored in a heated warehouse with natural
ventilation:
-
in manufacturer’s package – at ambient temperatures from +5 to +40
C and relative
humidity up to 80 % at +25
C;
-
unpacked – at ambient temperatures from +10 to +35
C and relative humidity up to 80 %
at +25
C.
6.2 The storage location should be free of dust, chemical vapours, aggressive gases and other
substances that may cause corrosion.
The storage location shall exclude exposure of the detectors to the direct rays of sunlight.
7 TRANSPORTATION
7.1 Detectors in the original manufacturer’s package can be transported by all means of
transport at any distance:
-
transportation by railway shall be carried out in clean boxcars;
-
when transported by air the boxes with detectors shall be placed in air-tight heated
compartment;
-
when transported by water and sea transport the boxes with detectors shall be placed in the
hold.
7.2 Arrangement and fastening of the boxes on transport means shall provide their steady
position en route, absence of displacement and striking each other.
7.3 The requirements of the inscriptions on the transport packing shall be observed during
loading and unloading.
7.4 Transportation conditions are as follows:
-
temperature …………………………………………………..….. from minus 25 to +50 °C;
-
humidity …………………………………….………………....…..… up to 98 % at +35 °C;
-
sinusoidal vibrations ………………………….. within frequency range from 10 to 55 Hz
with displacement amplitude 0.35 mm.
8 DISPOSAL
8.1 On full expiry of the detector (its component parts) service life as well as prior to its
dispatching for repair or calibration it shall be inspected for possible radioactive contamination of its
surfaces. Criteria for decision making on decontamination and further use shall comply with obligatory
requirements of national standards.
