Refuelling equipment: stations
TPG 304 02
CNG Refuelling stations for motor vehicles
This rule has been in effect since 1 February 2012.
These technical rules lay down the basic conditions for the location, construction and operation of CNG refuelling stations for motor vehicles. The continuously improving environmental standards and also the financial aspect have caused demand for natural gas as a motor fuel to recover.
CNG refuelling stations are not regarded as gas installations within the meaning of Act No 458/2000.
EARLIER REGULATIONS SUPERSEDED
These technical rules supersede TDG 304 02 approved on 13 December 2006.
Changes compared with the preceding TDG
CNG refuelling stations meeting the requirements of these technical rules can be classified as small stationary sources of air pollution within the meaning of Act No 86/2002. Environment Departments of Regional Authorities decide on such classification with finality.
Furthermore, safety zones have been specified for quick connect couplings during the connection and disconnection of the vehicle and the filling itself.
This TPG only applies to fast-fill CNG stations for motor vehicles, where the requirements for the station and the construction and maintenance thereof are subject to Act No 183/2006 on land use planning and building regulations.
These technical rules have been consulted with the relevant state administration authorities and with organisations that address this issue.
TDG 982 03
Refuelling appliances for CNG vehicles
This rule has been in effect since 1 February 2009
These technical recommendations lay down the basic conditions for the location, construction and operation of refuelling appliances for NGVs. The recommendations set out the requirements for safety at work and fire safety.
Refuelling appliances for NGVs are not regarded as gas installations within the meaning of Act No 458/2000.
Refuelling appliances for NGVs meeting the requirements of these recommendations have been classified as small stationary sources (up to 200 kW) of air pollution within the meaning of Act No 86/2002.
These technical recommendations have been consulted with the relevant state administration authorities and with organisations that address this issue, and are intended for verification in practice, see 9.2.
These technical recommendations lay down the conditions for the location, construction, testing and operation of refuelling appliances for time-fill of CNG vehicles. Refuelling appliances can be designed as type A or type B.
These technical recommendations apply to refuelling appliances with temperature compensation, which fill motor vehicles with natural gas up to an equivalent of 200 bar (15 °C), and to appliances without temperature compensation with the maximum pressure limited to 210 bar and meeting the following conditions, cumulatively:
- Maximum filling pressure 210 bar;
- Compressor capacity no more than 20 m3.h-1 (standard conditions);
- Internal volume of natural gas in the compressor no more than 0.5 m3 (standard conditions);
- Maximum number of fill hoses is 5;
- The total volume of CNG storage cylinders does not exceed 960 litres (geometrical volume).
For the purposes of these technical recommendations, the gas volumes and flow rates specified herein are related to standard reference conditions (standard conditions), a temperature of 15 °C and a pressure of 101.325 kPa under ČSN EN ISO 13443.
These technical recommendations do not apply to refuelling appliances, or refuelling stations, that do not meet the requirements specified in point 1.2, and to the assembling of refuelling appliances to form systems containing CNG storage cylinders. For such appliances, the conditions laid down in TPG 304 02 shall apply.
