The Bureau of Indian Standards (BIS) plays a crucial role in ensuring the safety, quality, and reliability of automotive components used across India. One such critical component is the multifunction valve assembly used in Liquefied Petroleum Gas (LPG) containers for automotive applications. Governed under IS 15100:2001, this standard specifies the requirements for the design, construction, performance, and testing of multifunction valve assemblies installed in LPG fuel tanks.
These valve assemblies are essential for controlling various functions such as filling, excess flow restriction, pressure relief, and gas discharge, ensuring safe operation under different conditions. As LPG is a highly flammable fuel stored under pressure, adherence to IS15100:2001 becomes vital to prevent hazards like leakage, overfilling, or explosion.
BIS certification under this standard ensures that manufacturers comply with stringent safety norms and quality benchmarks. It not only enhances product reliability but also builds consumer trust while supporting regulatory compliance in the automotive LPG sector.

bis certification process for multifunction valve assembly lpg containers
The BIS certification process for Multifunction Valve Assembly for LPG Containers for Automotive Use (IS 15100:2001) involves multiple regulatory and technical steps:
- Online Registration (Manak Portal): Manufacturers must register on the BIS Manak Portal and submit their application online under the applicable certification scheme. Foreign manufacturers are also required to submit a hard copy of the application along with all necessary supporting documents to BIS.
- Testing at BIS-Recognized Laboratory: Product samples of the multifunction valve assembly are tested in a BIS-recognized laboratory as per IS 15100:2001. The testing verifies compliance with key parameters such as pressure handling capacity, leak tightness, excess flow control, safety shut-off functions, durability, and material quality. Foreign manufacturers are advised to conduct pre-testing to ensure compliance.
- Application Submission: The manufacturer submits the complete application along with test reports, product design details, technical specifications, quality control procedures, and KYC documents. Foreign manufacturers must appoint an Authorized Indian Representative (AIR) for coordination with BIS.
- Factory Inspection: BIS officials carry out a detailed inspection of the manufacturing unit to evaluate production processes, assembly procedures, testing facilities, calibration of instruments, quality assurance systems, and adherence to IS 15100:2001 requirements.
- Grant of BIS License: After successful verification of documents, satisfactory test results, and factory inspection, BIS grants the certification license. For foreign manufacturers, the application is processed through the Foreign Manufacturers Certification Department (FMCD) before approval.
- Use of CML Number: Once the license is granted, the manufacturer is allotted a unique Certification Marks License (CML) number. This number must be affixed on each multifunction valve assembly along with the ISI mark, ensuring product safety, traceability, and compliance with Indian standards.

marking requirements , validity and timeline
marking requirements
Manufacturers obtaining BIS certification under IS 15100:2001 for Multifunction Valve Assembly for LPG Containers are required to comply with strict marking guidelines to ensure product authenticity, safety, and traceability. After the grant of the license from the Bureau of Indian Standards, each multifunction valve assembly must bear the Standard Mark (ISI Mark), indicating conformity with the applicable Indian Standard. The marking should include:
- The ISI Standard Mark
- The license number (CM/L number) issued by BIS
- Identification details such as manufacturer’s name or trademark
- Batch number or serial number for traceability
- Date or code of manufacture (as applicable)
The marking must be applied in a clear, visible, legible, and non-removable manner directly on the valve assembly. In cases where direct marking is not feasible due to size or design constraints, marking on the packaging may be permitted with prior BIS approval. Proper marking ensures that the valve assemblies used in LPG containers meet safety and regulatory requirements for automotive applications.
validity of bis license
The BIS certification license for Multifunction Valve Assembly for LPG Containers (IS 15100:2001) is typically granted for an initial period of one year. After the initial validity, manufacturers can renew the license for a period ranging from one to five years based on their compliance performance and preference.
To maintain the validity of the license, manufacturers must ensure:
- Continuous compliance with IS 15100:2001 requirements
- Consistent product quality through regular in-house testing
- Cooperation during BIS surveillance audits and inspections
- Timely payment of renewal and marking fees
Failure to comply with the standard or BIS guidelines may result in suspension or cancellation of the license.
