The Bureau of Indian Standards (BIS) has issued a Quality Control Order (QCO) for steel wires specifically used in umbrella ribs. This ensures that all steel wires, whether manufactured domestically or imported, meet strict safety, durability, and performance standards.
Understanding the BIS Standard for Umbrella Ribs
The steel wire must comply with IS 4223:1975, which defines the specifications for carbon steel wire suitable for umbrella ribs. The standard categorizes wires into three grades:
- Premium Grade – High-strength wire for luxury umbrellas.
- Standard Grade – Regular quality for everyday umbrellas.
- Economy Grade – Cost-effective option with basic durability.
Each grade is tested for tensile strength, flexibility, and surface finish, ensuring reliability during usage.
Key Points of the BIS QCO
- Mandatory Certification – Manufacturers must obtain a BIS license under Scheme-I of the BIS regulations.
- ISI Mark – All compliant wires must bear the ISI mark, signaling quality and standard adherence.
- Test Reports – Certification requires a laboratory test report from a BIS-approved lab.
- Exemptions – Wires manufactured for export with foreign standards may be exempt.
Failure to comply can result in penalties under the BIS Act, 2016.
Why Compliance Matters
Umbrella ribs are subject to bending, twisting, and environmental stress. Using wires that meet IS 4223:1975 ensures:
- Strength – Withstands repeated opening and closing.
- Durability – Resistant to rust and wear.
- Safety – Reduces risk of wire breakage and injury.
Meeting these standards boosts consumer confidence and supports a safer, high-quality product in the market.
Steps to Get BIS Certification
- Apply – Submit your product details to BIS for evaluation.
- Inspection – BIS inspects your manufacturing facility and tests the product.
- Compliance – Ensure processes meet IS 4223:1975 standards.
- License Issuance – Once approved, you receive a BIS license and can label your wire with the ISI mark.
Final Thoughts
The BIS QCO for steel wire in umbrella ribs is essential for maintaining product integrity, safety, and quality. By following IS 4223:1975, manufacturers can deliver durable umbrellas that meet consumer expectations while staying compliant with Indian standards.
