Getting BIS
Certification for Stainless Steel used in welding electrode core wire IS
10631:1983 demonstrates that you're meeting Indian quality and safety
standards. This certification confirms that the core wire has the essential
mechanical and chemical properties, ensuring it performs well and lasts in
various welding applications. To achieve this certification, manufacturers need
to go through BIS testing and approval.
To make sure this material performs properly during welding, the Bureau of Indian
Standards (BIS) has set guidelines under IS 10631:1983. This certification ensures that
the steel core wire meets the required quality, composition, and performance standards,
so it can be safely used for reliable welding results.
Overview of IS 10631:1983 Standard
This is an Indian Standard that defines the requirements for stainless steel used in
welding electrode core wire. It is issued by the Bureau of Indian Standards (BIS) to
ensure that the material is suitable for welding applications, and the material is:
- Made with the right chemical composition for proper welding performance
- Able to produce strong and reliable weld joints
- Resistant to corrosion and suitable for long-term use
- Designed to perform well under high temperature during welding
- Properly tested for quality, strength, and consistency
Who requires Steel Core Wire BIS Certification?
BIS certification as per IS 10631:1983 is required for all entities involved in the
production and sale of welding electrode core wire in India.
It’s applicable for :
- Manufacturers – Must obtain BIS certification for steel core wires made in India.
- Importers – Must ensure imported products are BIS certified before sale.
- Suppliers/Distributors – Must sell only BIS-compliant product in the market.
BIS Testing & Quality Standards for Welding Electrode Core Wire
To ensure proper welding performance, strength, and long service life of core wire, the Bureau of Indian Standards has defined strict testing and inspection requirements under IS 10631:1983. These tests are carried out during manufacturing and quality checks to maintain consistency and reliability of the materials.
What are R and S
- R (Required): Test must be carried out in the manufacturer’s in-house laboratory
- S (Subcontracting Allowed): Test can be done in a BIS-recognized or NABL-accredited external laboratory
Chemical Composition Tests
- Element Analysis Test (R) – Checks elements like carbon, silicon, manganese, chromium, nickel, etc. as per required composition
- Instrumental Chemical Analysis (S) – Uses spectrometer or chemical methods to verify accurate composition
Physical and Material Tests
- Freedom from Defects (R) – Ensures the material is free from cracks, flaws, or surface defects
- Size and Tolerance Check (R) – Confirms proper dimensions and uniform thickness of wire or billets
- Manufacturing Process Check (R) – Verifies that the material is produced as per standard requirements
Quality Control and Inspection
- Control Unit Testing (R)—Each batch or heat is tested to ensure consistency
- Test Records Maintenance (R)—Proper records are kept for all tests conducted
- Marking and Labelling Check (R) – Ensures correct BIS marking and product details are applied
How to Get BIS Certification for electrode core wires
The BIS certification process ensures that the product meets the required standard for proper and efficient operation as defined by the Bureau of Indian Standards (BIS).
The process includes the following steps:
- Online Registration: Manufacturers register on the BIS Manak Online Portal by submitting company details, factory information, and product specifications. Foreign manufacturers must appoint an Authorized Indian Representative (AIR) in India.
- Testing at BIS-Approved Laboratory: Product samples are tested in BIS-approved laboratories to evaluate electrical safety, insulation resistance, heating efficiency, durability, and overall performance as per requirements.
- Application Submission: The application is submitted along with laboratory test reports, technical documents, manufacturing process details, and factory information. Foreign manufacturers must also provide AIR-related documents.
- Factory Inspection: BIS officials conduct an on-site inspection of the manufacturing unit to verify production processes, quality control systems, safety measures, and compliance with the standard.
- Grant of BIS License: If all requirements are successfully met, BIS issues the certification license under Scheme-I, allowing the manufacturer to produce and sell certified products.
- Use of ISI Mark: After certification approval, the manufacturer is permitted to use the ISI mark along with a CM/L number on the product, confirming compliance with the standard.
