The effectiveness of a fire extinguisher depends entirely on the parts that trigger the firefighting
operation inside the extinguisher. The BIS Certification for Gas Cartridges for Use in Fire
Extinguishers becomes very crucial because a malfunctioning gas cartridge means that the fire
extinguisher will not work in case of an emergency. Gas cartridges are filled with compressed
gas which is used to eject the extinguishing agent from the fire extinguisher when it is activated
either manually or automatically.
In order to regulate gas cartridges and make sure that they meet all the requirements, the
Bureau of Indian Standards formulated IS 4947:2006. The certification process includes testing
of various parameters such as manufacturing standards, material specifications, dimensions,
pressure standards, etc. To get ISI marking, a manufacturer has to prove its conformity by
testing and inspection of its products.
Safety Requirements for IS 4947:2006
IS 4947:2006 is the Indian Standard that specifies the requirements for gas cartridges used in
fire extinguishers. The standard ensures that cartridges provide reliable discharge pressure,
maintain safety during storage, and perform effectively during emergency fire-fighting
operations. As per the Bureau of Indian Standards (BIS), these gas cartridges are:
- Evaluated for leakage
- Assessed for internal pressure resistance
- Checked for dimensional requirements
- Tested for burst strength
Who can apply for BIS Certification in India
BIS authorisation under IS 4947:2006 is required for businesses involved in manufacturing,
importing, or supplying Fire Safety Gas Cartridge in India.
Applicable to:
- Manufacturers (India) - Must get BIS approval if the Pressure Vessel Gas Cartridge are
covered under QCO.
- Foreign Manufacturers - Need certification to export the product to India.
- Importers/Brand Owners - Must ensure that the products are BIS-certified before sale.
- Sellers/Distributors - Should only sell certified Fire Extinguisher Components.
Testing and Inspection Requirements
To ensure that the performance of fire extinguishers is safe during emergencies, standards have
been set by the Bureau of Indian Standards for the gas cartridge as per IS 4947:2006. The
standard confirms the reliability of gas cartridges used in fire extinguishers from all aspects.
The BIS testing parameters and quality checks for the Gas Cartridges for use in Fire
Extinguishers are listed below:
Certification Process for Gas Cartridges for use in Fire
Extinguishers

The BIS Authorisation process ensures that the Fire Safety Gas Cartridge meet the required
standards for efficient operation. This process is set by the Bureau of Indian Standards (BIS)
and includes the following steps:
- Online Registration: Manufacturers register on the BIS Manak portal by submitting company, factory, and product details. Foreign manufacturers must appoint an Authorized Indian Representative (AIR).
- Testing at BIS-Approved Laboratory: Product samples are tested in BIS-approved laboratories for chemical composition, silica content, moisture content, fineness, compressive strength, and other physical performance parameters.
- Application Submission: The application is submitted along with test reports, technical documents, and factory details. Foreign manufacturers must also submit AIR-related documents.
- Factory Inspection: The Bureau of Indian Standards officials inspect the manufacturing units to verify the production process, safety measures, and quality control system.
- Grant of BIS License: Upon successful verification of all requirements, BIS grants the certification license under Scheme-I.
- Use of ISI Mark: Once approved, the manufacturer can use the ISI mark on the product with a CM/L number, confirming that the product meets BIS standards.

Marking Requirements & License Validity
Marking Requirements
Once the manufacturer is licensed with the BIS, the ISI Mark for Industrial Gas Cartridge needs
to be stamped either on the package or directly on the item itself. Information about the
manufacturer’s identification and license number (CM/L) also needs to be indicated in the
stamping. Additional information is provided below:
| Requirement | Details |
|---|
| ISI Mark | Indicates that the product is BIS certified and conforms to standards |
| Standard Number | IS 4947: 2006 |
| CML Number | Certification Marks License (CML) number issued by BIS |
| Manufacturer Details | Name of manufacturer or registered trademark |
| Batch / Date | Batch number, heat number, or manufacturing date for traceability |
Note: Marking is typically applied using durable stamping, tagging, or permanent printing to ensure clear identification during handling, storage, and transportation, as per BIS marking requirements.
