Testing the correctness and tightness of gas installations

According to the Law on Fire Protection and the Law on Flammable Liquids and Gases, the owners of buildings, building parts and spaces are obliged, among other things, to maintain gas installations and to have valid documentation for this.

The requirements that must be met by the gas system of the gas consumer are defined by valid regulations and norms, that is, in the case of non-standard or rarely used installations, European norms (EN) and other recognized rules of the profession are applied.

 

Gas tightness test

The correctness and tightness of the gas installation is carried out before commissioning, after construction or reconstruction, when the minimum technical conditions are met, and periodically.

Checking the correctness and tightness of gas installations

During this check, potential causes of malfunctioning of the gas installation are sought:

  • improper or unreliable installation of gas equipment or appliances
  • throughput of devices, equipment, consumables or pipelines
  • improper, unreliable or insufficient removal of flue gases or supply of combustion air
  • outdated, incorrect, unmaintained or unreliable condition of gas equipment, protective devices, regulatory devices and consumables
  • insufficient separation of heated parts of gas devices and equipment from combustible materials and parts of the building

The gas installation is correct if none of the listed defects were detected during the check. In the event that the gas installation is found to be faulty or leaky, or if the implementation is not carried out on time or before commissioning, the operator will withhold gas delivery to the consumer until the correctness of the gas installation is established.

Deadlines for testing the correctness and tightness of existing internal gas installations:

At least once every 8 years, it is necessary to determine the correctness and tightness of the gas installation for:

  • residential buildings up to 400 m2
  • individual apartment with an installed power consumption of up to 50 kW,
  • multi-apartment buildings, including common parts and individual apartments, which may also have special household gas devices for central heating with a total installed power of up to 50 kW.

At least once every 5 years, the correctness and tightness of the gas installation is tested for:

  • Legal entities (companies, trades, institutions, small businesses) that use consumers with an individual power of up to 50 kW and a total installed power of up to 100 kW

Every two years, the correctness and tightness of the gas installation is tested for:

  • technological plants where the gas installation is considered a tool for work, and individual power consumption exceeds 50 kW
  • technological plants with installed consumers with a total power of more than 100 kW
  • industrial kitchens with a total power consumption of up to 50 kW with natural ventilation
  • gas boilers with a total installed power of 50 to 350 kW
  • gas installations with a working pressure of 0.1 to 1 bar

At least once a year, the correctness and tightness of the gas installation is tested for:

  • gas boilers with a total installed power above 350 kW
  • gas installations with a working pressure greater than 1 bar
  • industrial kitchens with forced ventilation, regardless of the total installed power of the consumer

Tests can be performed exclusively by authorized company.
