CNG Cylinders Hydrotest Certificate Is Mandatory
Ensure Safety. Stay Compliant. Refuel Without Hassle.
As per Rule 35(1) of the Gas Cylinders (Amended) Rules, 2025, every CNG cylinder must undergo mandatory hydrostatic testing (hydrotest) once every 3 years at a PESO-approved cylinder testing centre.
π Key Compliance Requirements
β
Mandatory Hydrotesting: CNG cylinders must be retested every 3 years to check for leaks, corrosion, structural defects and safety.
β
No Valid Certificate, No Refuelling: IGL is enforcing strict checks to prevent CNG dispensing to vehicles without a valid hydrotest certificate.
β
AI-Powered Verification: Automated camera systems linked to PESO databases, along with station staff checks, help verify vehicle details and cylinder testing status before refuelling.
β
Keep Your Certificate in the Vehicle: Vehicle owners must carry a valid hydrotest certificate inside their vehicle.
β οΈ Important: An expired or missing hydrotest certificate can lead to refuelling being denied. Get your CNG cylinder tested on time and keep your documents ready.
