BIS Certification for Hard Drawn Steel Wire For Upholstery Springs IS 2589: 1975

• Manufactured with the correct steel quality to achieve high tensile strength
• Strong enough to withstand repeated compression without breaking
• Flexible enough to maintain shape and spring action in upholstery use
• Suitable for long-term durability in furniture applications
• Properly tested for mechanical strength, size accuracy, and performance consistency

BIS certification as per IS 2589:1975 is required for all entities involved in the production and sale of these steel wires in India. It’s applicable for :

1. Manufacturers – Must obtain BIS certification for hard-drawn steel wires made in India.
2. Importers – Must ensure imported products are BIS certified before sale.
3. Suppliers/Distributors – Must sell only BIS-compliant product in the market.

• R (Required): Tests must be carried out in the manufacturer’s in-house testing facility
• S (Subcontracting Allowed): Tests can be conducted in BIS-recognized or NABL-accredited external laboratories

• Ladle Composition Check (R) – Confirms correct levels of carbon, silicon, manganese, sulphur, and phosphorus during steel making
• Product Composition Review (S) – Verifies final wire composition against standard limits after processing
• Impurity Control Assessment (R) – Ensures no harmful additional elements are present beyond specified limits

• Diameter Measurement Control (R) – Ensures wire size matches standard ranges with permitted tolerances
• Shape Uniformity Check (R) – Confirms ovality and roundness consistency across wire cross-section
• Size Variation Inspection (R) – Verifies that drawn wire maintains uniform thickness along its length

• Tensile Strength Evaluation (R) – Tests wire strength under load to ensure proper spring performance
• Elastic Behaviour Check (R) – Confirms ability to withstand stretching without failure
• Twisting Resistance Test (S) – Assesses wire durability under torsional stress (for specific wire types)
• Bending Endurance Test (S) – Checks flexibility and resistance to repeated bending without breakage
• Coiling Performance Test (S) – Ensures wire can be formed into springs without cracking or fracture

• Surface Defect Examination (R) – Ensures wire is free from cracks, rust, seams, or harmful imperfections
• Straightness and Flatness Check (R) – Confirms wire does not show waviness or unwanted curvature
• Finish Quality Assessment (R) – Verifies proper phosphate-drawn or coated finish as per requirement

1. 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.
2. 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.
3. 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.
4. 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.
5. 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.
6. 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.

• Application fee for foreign manufacturers is payable via SWIFT (SAARC countries may pay in INR with applicable GST).
• Audit charges for foreign manufacturers vary based on country/location.
• Marking fee depends on the product category and production volume (MSME benefits may apply).
• Testing charges are paid directly to BIS-approved laboratories.
• Consultancy fees depend on product type and factory location.
