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.
