The 5-Step PESO Hydrostatic Testing Procedure

Standard operating procedure prescribed by PESO (Petroleum & Explosives Safety Organisation) for CNG cylinder re-certification:

Step 1: Degasification Residual CNG is safely purged through nitrogen blanketing to ensure zero volatile vapors remain inside the vessel.
Step 2: Internal Inspection An endoscope camera inspects the interior vessel walls for pitting, corrosion, or hairline micro-fractures.
Step 3: 330 Bar Hydro Test The cylinder is submerged into a water jacket and pressurized to 330 Bar (1.5x working pressure) to measure permanent volumetric expansion.
Step 4: Tare Weight Check The cylinder is dried and weighed. If wall thinning exceeds 5% of original manufacturer tare weight, the cylinder is condemned.
Step 5: Collar Punch & Stamp A metal compliance plate is affixed to the brass collar with the test date and center code, and a digital QR certificate is uploaded to Parivahan.

Is CNG cylinder testing mandatory in Pune?

Yes. Under Rule 35 of the Gas Cylinder Rules, 2016 issued by the Petroleum and Explosives Safety Organisation (PESO), Ministry of Commerce and Industry, every automotive CNG cylinder must undergo hydrostatic testing every 3 years. Driving with an overdue cylinder attracts a ₹10,000 fine under the Motor Vehicles Act, and authorized CGD pumps (Maharashtra Natural Gas (MNGL)) are legally prohibited from refueling non-compliant vehicles.

What is the standard cost for CNG cylinder testing in Pune?

Government-regulated testing charges in Pune typically range between ₹1,500 and ₹2,200 depending on vehicle class (private passenger car vs. commercial taxi/auto). This includes cylinder de-gasification, hydrostatic water-jacket testing at 330 bar, tare weight re-verification, collar plate date punching, and issuance of the digital Green Fitness Certificate.

How long does the cylinder hydro-testing process take?

Hydrostatic re-testing takes approximately 3 to 4 hours. You can drop off your vehicle or standalone cylinder in the morning and collect the certified cylinder with the freshly punched brass collar plate and QR fitness certificate the same afternoon.
