BIS ISI Certification for Domestic LPG Gas Stoves in India (IS 4246)

The kitchen gas stove is one of the most safety-critical appliances in an Indian home. It handles a pressurised, flammable fuel next to an open flame, every day. That is why BIS made the ISI mark compulsory for domestic LPG stoves, and why both manufacturers and importers need a valid BIS licence before the product reaches a shop, a distributor or an online marketplace.

The governing standard is IS 4246:2002 — Domestic Gas Stoves for use with Liquefied Petroleum Gases. It applies to single-, two-, three- and four-burner stoves, stainless-steel and glass-top designs, and manual or auto-ignition models alike.

🛡️ What Is BIS ISI (Scheme-I) Certification?

BIS Scheme-I is the ISI mark scheme under the BIS (Conformity Assessment) Regulations, 2018. Unlike the Compulsory Registration Scheme (CRS) for electronics, where a lab report supports a registration, ISI certification is a licence granted to a specific factory after product testing and a physical inspection of the manufacturing and testing facilities. After grant, the licensee marks every unit with the ISI mark and its CM/L licence number and stays under BIS surveillance (market and factory samples).

For domestic LPG gas stoves, that means the licence belongs to the factory that actually makes the product. Brand owners and importers cannot hold it in their own name for goods made elsewhere. See our ISI vs Standard Mark vs CRS comparison for how the schemes differ.

📜 The Governing Order & Amendments

1. Domestic Gas Stoves for use with Liquefied Petroleum Gases (Quality Control) Order, 2019S.O. 4345(E) dated 3 December 2019

The QCO applies equally to Indian manufacturers and to foreign manufacturers exporting to India. Imported stoves without the ISI mark can be held at customs, and e-commerce platforms routinely delist uncertified listings.

🔬 What BIS Testing Verifies for Lpg Gas Stoves

Testing is carried out at a BIS-recognised laboratory (or under BIS supervision), and the same parameters are re-checked during surveillance. The key areas for domestic LPG gas stoves:

🧭 Step-by-Step ISI Licensing Process

1. Scope & standard mappingConfirm every model is within the QCO, map it to its IS number and current edition, and group models into a series for testing.
2. Set up in-house testingInstall the equipment and trained staff needed for the routine tests in the BIS Scheme of Testing & Inspection (STI) for the standard.
3. Product testingGet representative samples tested against the full standard at a BIS-recognised lab and draw a complete test report.
4. Online applicationIndian factories apply on Manakonline. Foreign factories apply under FMCS, which went online in June 2026, with an Authorised Indian Representative. Pay the application and processing fees.
5. Factory inspectionA BIS officer audits production, raw-material control and in-house testing, witnesses tests and draws samples. Use our factory audit checklist to prepare.
6. Licence grantOn satisfactory results, BIS grants the licence (CM/L number). Foreign manufacturers also furnish the performance bank guarantee required under FMCS.
7. Marking & surveillanceApply the ISI mark with the CM/L number, pay the annual marking fee, keep test records, and renew the licence before expiry.

🗂️ Documents Required

Standard dossier (every ISI application):

• Factory registration / incorporation documents and address proof of the manufacturing premises
• Manufacturing process flow chart and list of outsourced processes (if any)
• List of production machinery and in-house test equipment, with calibration certificates
• Details and qualifications of the quality-control in-charge
• Product test report from a BIS-recognised laboratory
• Factory layout, location map, and the proposed ISI marking / label artwork
• For foreign factories: AIR nomination and undertaking, and trademark / brand authorisation where applicable

Specific to domestic LPG gas stoves:

• Model list with burner count, burner rating (kW), body material (SS / toughened glass) and ignition type for each model
• Gas-circuit drawing showing valves, nozzles, the manifold and inlet connection
• Bill of materials for burners, valves, nozzles and the glass top, with supplier names
• Calibrated test equipment list: gas flow meter, CO analyser, manometer, thermocouples

⏱️ Timeline & Validity at a Glance

Timelines depend mainly on how complete the first file is and how quickly the factory inspection can be scheduled. For foreign factories, inspection scheduling and officer travel usually decide the overall timeline. Every BIS query adds time, so a clean, complete first submission is the biggest lever you have.

⚠️ Common Mistakes That Delay a Lpg Gas Stove Licence

• Testing the wrong nozzle — Nozzles sized for export LPG compositions or other markets can fail the heat-input and efficiency limits on Indian LPG.
• Ignoring BEE — Getting the ISI licence but not registering for the BEE star label. Both are needed before sale.
• Undeclared models — Selling a 3-burner glass-top that was never added to the licence. Every model sold must be covered.
• Weak in-house lab — The factory audit checks whether the routine tests in the Scheme of Testing & Inspection can actually be done on site.
