No Hydro-Test Certificate? No CNG in Delhi

Published: 11 September 2026 · 1 min read

What Happened

The Delhi government has ordered strict enforcement of mandatory hydro-testing for CNG cylinders. Vehicles whose hydro-test certificates have expired, or cannot produce one, will now be denied CNG refuelling at stations. Under the rules, CNG cylinders must undergo a hydro test every three years to check for leaks, cracks and structural damage. The move follows an August 19 CNG cylinder explosion that killed three workers and injured three others.

Key Takeaways

CNG vehicle owners in Delhi must keep a valid hydro-test certificate issued by a Petroleum and Explosives Safety Organisation (PESO)-approved testing centre. Indraprastha Gas Limited (IGL) has already begun checking certificates before refuelling.
