NBN/DTD B 61-002:2021 standard – Accredited body
LPG high power inspection > 70 kW
Compliance inspection for industrial propane installations, agricultural sites and technical processes. Specialised inspectors for high-power LPG.
Pricing
LPG inspection for installations > 70 kW
Propane or butane installations exceeding 70 kW are governed by the NBN/DTD B 61-002:2021 standard. These configurations are mainly found in industrial, agricultural or isolated contexts requiring significant heating capacity.
LPG provides an energy alternative in areas not served by the natural gas network, with specific safety requirements linked to the nature of this heavier-than-air gas.
Scope of the inspection
Our inspection covers the internal installation: distribution network, combustion appliances, ventilation and safety devices. The storage tank itself is inspected by your gas supplier as part of your contract.
Inspected installation

Sectors concerned
Industry, agriculture, horticulture, livestock
Applications of high-power LPG inspection
The inspection applies to all propane/butane installations exceeding 70 kW, mainly in industrial and agricultural sectors.
Industrial processes
Ovens, dryers, kilns and production installations using propane as an energy source.
Agricultural operations
Crop drying, livestock building heating, large-scale thermal weed control.
Horticultural greenhouses
Heating professional greenhouses with high and continuous energy demand.
Warehouses and hangars
Heating large volumes in areas not connected to the natural gas grid.
Food industry
Cooking, sterilisation and thermal processes in the food production sector.
Isolated sites
Any installation requiring high heating power without access to the gas network.
Safety requirements specific to LPG
High-power LPG installations present specific risks. The inspector verifies all safety devices of the internal installation (the tank itself is inspected by your gas supplier).
Leak detection
Mandatory gas detection systems in technical rooms, with alarm and automatic shut-off.
Reinforced ventilation
As LPG is heavier than air, efficient low-level ventilation is essential to evacuate leaks.
Safety distances
Large-capacity tanks must comply with strict minimum distances from buildings and property boundaries.
Safety valves
Main shut-off, solenoid valves, flow limiters and non-return devices are inspected and tested.
Pressure control
Regulators, pressure reducers and safety valves sized for the high flow rates of large installations.
Signage and access
Regulatory markings, fire brigade access, extinguishing means and visible safety instructions.
Frequently asked questions – High-power LPG
Answers to the common questions of professionals using LPG.
Does the inspection include the storage tank?
No, our inspection covers exclusively the distribution and use installation (downstream of the tank outlet valve). The tank itself is inspected by the tank owner (usually your propane supplier) under the pressure equipment regulations.
How often must an industrial LPG installation be inspected?
The frequency depends on the applicable regulation and your insurer’s requirements. An annual or biennial inspection is generally recommended for high-power installations.
Do you provide the isometric diagram?
Yes, the Certinergie inspector can draw the isometric diagram of your gas installation on site for an additional fee. This document represents the entire pipework and is often required by suppliers or insurers.
Can you intervene on SEVESO sites?
We work on gas distribution and use installations. For SEVESO sites, coordination with your safety officer is required. Our inspectors are trained in the safety procedures of sensitive industrial sites.
How is the inspection of an agricultural installation carried out?
The inspector checks the full distribution network from the tank outlet to the appliances (greenhouse heating, dryer, etc.). Safety devices, technical room ventilation and connection compliance are also verified.
Do you offer preventive maintenance contracts?
We offer framework contracts including scheduled inspection visits, a dedicated contact and preferential rates. Contact our B2B department for a proposal tailored to your installation portfolio.
