Introduction
A major provider of lifting solutions from Gujarat lost a large industrial contract when the client refused to accept their flat woven webbing slings which did not have BIS certification. The client insisted that the flat woven webbing slings produced be clearly marked with the ISI (Indian Standards Institute) mark per IS 15041:2001.This example highlights how important certification IS.
This example is what commonly happens to manufacturers of flat woven webbing slings made out of man-made fibers for general service. If a product has no BIS certification, the product simply cannot be legally sold in India, meaning that manufacturers risk losing business, tenders, and customers’ trust.
The BIS certification of slings means that the products have met required laws and the product is safe and durable, which provides the manufacturer with the legal protection with respect to the competitive advantage around strength in other Indian markets and the international arena.
What is IS 15041:2001?
IS 15041:2001 is the Indian Standard issued by the Bureau of Indian Standards (BIS) that specifies the quality, safety, and performance requirements for flat woven webbing slings made from man-made fibres for general services.
It covers:
- Material Specifications: Defines acceptable man-made fibres for manufacturing slings.
- Strength Requirements: Ensures slings can safely handle specified loads.
- Performance Testing: Includes tests for tensile strength, elongation, abrasion resistance, and durability.
- Safety Standards: Guarantees slings are reliable for lifting, construction, and industrial applications.
In short, IS 15041:2001 ensures that all certified flat woven webbing slings are safe, durable, and compliant with Indian industrial standards.
Why BIS Certification is Mandatory for Flat Woven Webbing Slings Made is Essential
- Assures Safety and Reliability
Flat woven webbing slings are widely used in lifting, construction, and industrial transport. Any failure due to poor-quality slings can cause accidents, property damage, or injuries. BIS certification ensures that slings are manufactured to IS 15041:2001 standards, making them strong, durable, and safe to use. - Legal Compliance in India
The Bureau of Indian Standards (BIS) mandates that all flat woven webbing slings made from man-made fibres for general services must be BIS-certified before sale. Selling non-certified slings is illegal and can lead to fines, product seizure, or legal action. - Builds Customer Trust
The ISI mark on BIS-certified slings is a visible symbol of quality and credibility. Clients, contractors, and industrial buyers often insist on ISI-marked products because it guarantees consistency, safety, and compliance. - Market Advantage and Tender Eligibility
Government and large industrial tenders require BIS-certified slings. Without certification, manufacturers may lose major contracts. Certification not only opens doors for domestic tenders but also enhances export potential, as international buyers prefer verified, standard-compliant products. - Standardized Quality Assurance
BIS certification ensures all slings undergo rigorous testing for tensile strength, elongation, abrasion resistance, and load-bearing capacity. Manufacturers must maintain a proper quality control system, ensuring uniformity across all products. - Protects Brand Reputation
Using BIS-certified slings demonstrates professionalism and commitment to quality. It reduces the risk of product failure in the field, which protects the manufacturer’s brand and builds long-term trust with clients. - Supports National Industrial Standards
By adhering to IS 15041:2001, manufacturers contribute to “Make in India” quality initiatives and promote standardization in the lifting and industrial sectors.
Understanding the ISI Mark
The ISI Mark on flat woven webbing slings indicates that:
- The sling complies with IS 15041:2001
- Manufacturing quality is consistent and controlled
- Safety and performance standards are verified by BIS inspections
Manufacturers must obtain a BIS license before using the ISI mark on their products.
