Tee and strap hinges are commonly used in gates, wooden doors, storage boxes, garage
shutters, and agricultural structures. These hinges consist of an elongated metal strap that
evenly distributes the weight and increases the stability of the heavy or large objects. They have
a very simple construction and hence are highly suitable for both interior and exterior
applications. Depending upon their particular application requirements, Tee and Strap hinges
come in different dimensions and capacities.
Unlike decorative hardware products, structural hinges require constant movement and
performance under changing load situations. The quality and dimension parameters of the
hinges are ensured by BIS certification under IS 206: 2010. It also ensures that the product is
durable and reliable in its operation. Companies must get the product approval certificate to sell
the hinges in the market.
What is IS 206: 2010?
This is the Indian Standard for tee and strap hinges used in doors, gates, windows, and other
hardware fittings. It mentions the requirement for quality workmanship to ensure reliable
operation and long service life of hinges in furniture. As per the BIS (Bureau of Indian
Standards), these tee hinges are:
- Assessed for material quality
- Checked for fitment requirements
- Tested for load-bearing strength
- Examined for durability
Strap Hinge BIS Approval Eligibility Criteria
BIS authorisation under IS 206: 2010 is required for businesses involved in manufacturing, importing, or supplying industrial hinges in India.
Applicable to:
- Manufacturers (India) - Must get BIS approval if the Tee hinge and strap hinge are covered under QCO.
- Foreign Manufacturers - Need certification to export the products to India.
- Importers/Brand Owners - Must ensure that the products are BIS-certified before sale.
- Sellers/Distributors - Should only sell certified Metal hinges.
Testing and Inspection Requirements
To ensure reliable performance of hardware fittings used in doors and windows, the Bureau of Indian Standards outlines the minimum requirements under IS 206: 2010. This certification ensures that manufacturers produce tee and strap hinges with adequate strength and proper dimensional accuracy for long-term use. The BIS testing parameters and quality checks for the Hinges are listed below:
| Test Group | What is Tested | Purpose |
|---|
| Dimension Test | Length, width, flap size, thickness, and overall hinge dimensions | Ensures dimensional accuracy and standard conformity |
| Construction & Workmanship Test | Assembly quality, alignment, riveting, and overall finishing | Ensures proper manufacturing and defect-free construction |
| Load Bearing Test | Ability of hinge to support applied load without deformation | Ensures safe functional performance in doors and shutters |
| Operational Movement Test | Smooth rotation and repeated opening/closing performance | Ensures functional reliability during usage |
| Wear & Friction Test | Resistance to wear under repeated motion | Ensures long-term durability and reduced failure risk |
| Surface Finish Inspection | Smoothness, coating quality, and absence of surface defects | Ensures aesthetic quality and corrosion resistance |
| Corrosion Resistance Check | Resistance to rust and environmental exposure | Ensures suitability for long-term use in varying conditions |
| Pin Strength Test | Strength and stability of hinge pin under load | Ensures secure joint performance and structural stability |
| Fixing Hole Alignment Test | Accuracy and alignment of screw holes | Ensures easy installation and proper fitting |
Steps for Heavy Duty Strap Hinge BIS Approval
The BIS Authorisation process ensures that the Tee & Strap Hinges meet the required
standards for proper and 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 physical properties, moisture content, chemical characteristics, dimensional stability, and overall material performance.
- 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.

the manufacturer’s identification and licence number (CM/L) must be mentioned. This ensures
the product complies with all safety and quality standards. Further details are provided below:
| Requirement | Details |
|---|
| ISI Mark | Indicates that the product is BIS certified and conforms to standards |
| Standard Number | IS 206: 2010 |
| 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 |
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.
