BIS ISI Certification for Steel Butt Hinges as per IS 1341:2018
Introduction
Steel butt hinges are essential hardware components used in residential, commercial, and industrial buildings. They are widely installed in doors, windows, cabinets, and other applications where smooth movement, strength, and durability are required. To ensure consistent product quality and performance, the Bureau of Indian Standards (BIS) has established IS 1341:2018 – Steel Butt Hinges, which specifies requirements for steel butt hinges.
BIS ISI Certification for Steel Butt Hinges helps manufacturers demonstrate that their products conform to the applicable Indian Standard. It also supports compliance with the relevant government quality control requirements for hinges manufactured, imported, or sold in India. <escape>1</escape>

BIS ISI Certification Process for Steel Butt Hinges
Manufacturers seeking BIS certification should follow the applicable product certification procedure under Scheme I.
Step 1: Review the Applicable Indian Standard
Obtain and review IS 1341:2018, including applicable amendments, to understand the material, design, dimensional, workmanship, and finish requirements.
Step 2: Assess Manufacturing Facilities
The manufacturer should have suitable production machinery, manufacturing infrastructure, process controls, and quality assurance arrangements to produce compliant steel butt hinges.
Step 3: Establish Testing Facilities
The manufacturer must establish appropriate quality control and testing capabilities as required by the standard and BIS certification scheme. Where applicable, testing may be conducted through recognised external laboratories or other permitted arrangements.
Step 4: Prepare the Required Documents
Prepare the applicable technical and business documents, which may include:
-
Manufacturing unit details and address proof
-
Factory layout and manufacturing process flow
-
Machinery and testing equipment details
-
Raw material specifications and supplier details
-
Quality control and inspection procedures
-
Test reports, where applicable
-
Product drawings, types, sizes, and technical specifications
-
Details of the authorised signatory and applicable business registrations
The precise documentation requirements depend on the application route and the current BIS guidelines.
Step 5: Submit the BIS Application
Submit the application through the official BIS online certification portal, along with the prescribed information and applicable fees.
Step 6: Factory Assessment and Product Testing
BIS evaluates the manufacturing and quality control arrangements. Product samples are tested to verify conformity with the applicable Indian Standard. The assessment and testing requirements depend on the certification route and current BIS procedures.
Step 7: Grant of BIS Licence
If the manufacturer satisfies the applicable requirements and BIS approves the application, a licence may be granted for the specified product scope.
Step 8: Use the ISI Mark Correctly
After obtaining the licence, the manufacturer must use the BIS Standard Mark in accordance with the licence conditions and applicable marking requirements. The mark must not be used on products outside the approved scope.
Testing Requirements for Steel Butt Hinges
Product testing is a key part of the BIS certification process. For steel butt hinges, the relevant requirements are specified in IS 1341:2018 and the associated BIS certification documentation.
Depending on the applicable clauses and product type, verification may include:
-
Material conformity and chemical composition
-
Overall hinge dimensions and tolerances
-
Flap thickness and other specified dimensions
-
Hinge pin and knuckle requirements
-
Screw-hole dimensions and positioning
-
Workmanship and construction
-
Surface finish and appearance
The actual test plan must be based on the current standard, the relevant product type and size, and the applicable BIS product manual. Manufacturers should not rely solely on a generic checklist when preparing for testing.
Documents Required for BIS ISI Certification
Preparing the documentation in advance can help manufacturers organise their application and assessment process.
Commonly relevant documents include:
| Document | Purpose |
|---|---|
| Business registration documents | Establish the legal identity of the applicant |
| Factory address proof | Verify the manufacturing location |
| Manufacturing process flow chart | Explain the production process |
| Machinery list | Demonstrate production capability |
| Testing equipment list | Establish quality control and testing capability |
| Product drawings and specifications | Identify the product types and sizes |
| Raw material details | Support conformity with material requirements |
| Quality control records and procedures | Demonstrate consistent manufacturing controls |
| Authorisation documents | Identify the authorised applicant representative |
This list is indicative. The current BIS application requirements should be checked before submission.
Benefits of BIS Certification for Manufacturers
Obtaining BIS certification can offer several benefits to steel butt hinge manufacturers:
-
