What are the hydro test and compliance plate? You won't get CNG if they have expired..

CNG prices have been hiked in the Delhi-NCR region. IGL has increased the price of CNG by ₹3.89. If you own a CNG vehicle, this new notification from Indraprastha Gas Limited (IGL) is crucial for you. CNG will no longer be refilled in vehicles that have not undergone a safety inspection of their CNG cylinders; only vehicles with a completed inspection will be supplied with CNG. IGL has displayed this information on notice boards.

IGL's notification states that CNG will not be refilled if the hydro test or compliance plate has expired. Therefore, you should check the status of the hydro test and compliance plate before attempting to refuel with CNG.

What is a hydro test?
It is mandatory to conduct a hydro test on the cylinder used for CNG in the vehicle. The hydro test checks the structural integrity and gas-tightness of pressure-bearing components like the CNG cylinder, pipes, and tank, ensuring a comprehensive safety assessment of your CNG cylinder. If your vehicle's hydro test has expired, CNG will not be refilled. Please note that the hydro test for CNG cylinders must be conducted every three years.

What is a compliance plate?
Compliance plates are used on CNG vehicles. They indicate whether your vehicle's CNG kit and cylinder comply with safety regulations. The plate also displays essential vehicle details, such as information regarding the hydro test, the date of CNG kit installation, and verification of the cylinder number. In short, to get your vehicle refueled with CNG, you must have a valid (non-expired) compliance plate.
