  • Page 118: Storage

    8 STORAGE 8.1 The radiometers should be stored in a packing box in heated and ventilated storehouses with air-conditioning at the ambient temperature from + 5 to + 40 °C and relative humidity up to 80 % at + 25 °C temperature, non-condensing. The storehouse should be free of acids, gas, vapors of organic solvents, and alkali that may cause corrosion.

  • Page 119: Shipping

    9 SHIPPING 9.1 Packed radiometers may be shipped by any kinds of closed transport vehicles under the conditions with temperature limitation in the range of - 25 to + 55 о С, and according to rules and standards effective for each means of transport. 9.2 The radiometers in shipping container should be placed and fixed in the vehicle to ensure their stable position and to avoid shocks (with each other and the sidewalls of the transport).

  • Page 120: Disposal

    10 DISPOSAL Disposal of the radiometer is performed in compliance with the general rules, i.e. metals are recycled or melted, and plastic parts are dumped. Disposal of the radiometer is not dangerous for service personnel, and is environmentally friendly.
