BIS Certification for Steel Wire For Nipples For Spokes IS 8564: 1977

• Produced using suitable steel to achieve required strength levels
• Capable of handling tension and load applied in spoke assemblies
• Resistant to wear during continuous use in rotating wheels
• Suitable for maintaining proper wheel alignment and balance
• Tested for key parameters such as mechanical properties, dimensions, and consistency across batches

BIS certification as per IS 8564 is required for all entities involved in the production and sale of these spoke steel wires in India. It’s applicable for :

1. Manufacturers – Must obtain BIS certification for 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 that must be conducted in the manufacturer’s in-house laboratory
• S (Subcontracting Allowed): Tests that can be done in BIS-recognized or NABL-accredited external labs

• Ladle Analysis (R): Checks correct levels of carbon, manganese, sulphur, phosphorus during steel production
• Product Composition Check (S): Confirms final wire composition after processing meets IS limits
• Impurity Control (R): Ensures unwanted elements are within permissible range

• Diameter Measurement (R): Verifies wire thickness is within standard tolerance
• Roundness Check (R): Ensures uniform cross-section for proper fitting in nipples
• Length and Uniformity (R): Confirms consistent wire size without variation along length

• Tensile Strength Test (R): Confirms wire can withstand required load in spoke applications
• Elongation Test (R): Checks flexibility before fracture under stress
• Twist Test (S): Assesses behaviour under torsional force
• Wrap/Bending Test (S): Ensures wire does not crack during bending or coiling

• Surface Defects Check (R): Ensures wire is free from cracks, seams, rust, or pits
• Finish Quality (R): Confirms smooth surface suitable for nipple manufacturing
• Straightness Check (R): Ensures proper alignment for smooth processing and assembly

1. Online Registration: Register on the BIS Manak Online Portal with company details, factory address, and product information. Foreign manufacturers must appoint an Authorized Indian Representative (AIR) in India.
2. Product Testing: Send product samples to BIS-approved laboratories. The wire is tested for chemical composition, strength, dimensions, and surface quality as per IS.
3. Application Submission: Submit the application along with test reports, manufacturing details, and quality documents. AIR documents are required for foreign applicants.
4. Factory Inspection: BIS officials inspect the manufacturing unit to check the production process, equipment, and quality control systems.
5. License Approval: If all requirements are satisfied, BIS issues the license under Scheme-I for manufacturing and selling the product in India.
6. ISI Mark Usage: After approval, the manufacturer can use the ISI mark with a CM/L number on the product, confirming compliance with the standard.
