BIS Certification for Steel Butt Hinges

Steel butt hinges are used in doors, windows, cabinets, and furniture for easy and steady movement while opening and closing the door. The hinge consists of two metallic plates joined through a pin system that helps rotate the plates and support the load of the joined component. Strength and corrosion resistance features of steel butt hinges make them appropriate for domestic, commercial, and industrial use. Various types of steel butt hinges of different load capacities are available in the market.

In order to ensure reliable performance and consistency in the product, BIS certification is necessary. As per IS 1341: 2018, the product is checked for its dimensions, quality, material, finish, strength and performance. Manufacturers must obtain the product certification to ensure the efficiency of the hinges in the long term.

What is IS 1341: 2018?

This is the Indian Standard for steel butt hinges used in doors, windows, cabinets, gates, and furniture fittings. It mentions the dimensional accuracy and manufacturing quality to ensure the long-term durability of hinges. As per the BIS (Bureau of Indian Standards), these steel butt hinges are:

Checked for design conformity
Assessed for corrosion resistance
Evaluated for durability
Tested for load-bearing strength

Who is eligible for Steel Hinge BIS Approval?

BIS authorisation under IS 1341: 2018 is required for businesses involved in manufacturing, importing, or supplying hardware hinges in India.

Applicable to:

Manufacturers (India) - Must get BIS approval if the corrosion-resistant hinge is 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 industrial hinges.

Testing and Inspection Requirements

To ensure consistent performance of steel butt hinges in doors, windows, and furniture fittings, the Bureau of Indian Standards outlines the minimum requirements under IS 1341: 2018. This certification ensures that manufacturers produce hinges with adequate strength and proper dimensions for long-term mechanical operation. 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, pin diameter, and overall hinge dimensions	Ensures dimensional accuracy and conformity to IS 1341 requirements
Construction & Assembly Test	Hinge assembly, pin fitting, flap alignment, and joint integrity	Ensures proper manufacturing and structural reliability
Load Bearing Test	Ability of hinge to support specified door/shutter weight	Ensures safe functional performance under applied load
Operational Movement Test	Smooth opening and closing cycles of hinge	Ensures consistent performance during repeated usage
Wear & Tear Test	Performance under repeated friction and motion cycles	Ensures long-term durability and reduced mechanical failure
Finish Quality Inspection	Surface finish, coating uniformity, and corrosion protection	Ensures aesthetic quality and resistance to rusting
Corrosion Resistance Test	Exposure to moisture and environmental conditions	Ensures suitability for indoor and outdoor applications
Pin Strength Test	Strength and integrity of hinge pin under stress	Ensures secure joint performance without deformation
Fixing Hole Alignment Test	Accuracy and alignment of screw holes	Ensures easy installation and proper fitting

Steps for Butt Hinge BIS License

The BIS Authorisation process ensures that the metal 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.

Standard Number	IS 1341: 2018
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.

Validity for structural hinge BIS License

particulars	Details
Initial Validity	Typically 1 to 2 years, depending on BIS approval conditions
Renewal	Must be renewed before expiry by submitting the application along with the prescribed fee and updated documents
