- The BIS for Ropes and Cordages ensures that the ropes and cordages conform to IS 1084:2005 and is meant to indicate the product’s strength, pliability, and durability.
- The ISI Mark indicates that ropes and cordages conform to rigid safety and performance specifications.
- Diligence Certification assists manufacturers from product testing to the final approval of the BIS license.
Introduction
In 2024, an Indian marine supply manufacturer lost a substantial export contract because their synthetic ropes could not pass the BIS test due to variations in tensile strength. The organization had made the distinction because their competitor did have an ISI Mark issued under IS 1084:2005 which demonstrated to buyers that the ropes were reliable and met standards. That one difference caused success or loss.
Today, Indian and international buyers expect all industry products to be BIS certified with the largest emphasis on industrial material products such as ropes and cordages which are very important in the construction, marine, agriculture, and transportation industries.
This is where the BIS for Ropes and Cordages matters and provides assurance of quality, safety, and durability undertaken through a Bureau of Indian Standards (BIS) scheme
What is BIS for Ropes and Cordages?
The BIS for Ropes and Cordages verifies that the product meets IS 1084:2005 – Specification for Ropes and Cordages.
These certifications verify that ropes made from natural fibres (such as jute, coir, or cotton) or synthetic fibres (such as polypropylene, polyester, or nylon) meet the minimum performance criteria tensile strength, elongation, and breaking load.
When a manufacturer is granted the ISI Mark, it is their guarantee to the customer that every meter of rope has been tested and is suitable for use in meeting the highest level of safety and durability in India.
Applicable Standard: IS 1084:2005 Explained
The Indian Standard IS 1084:2005, titled “Ropes and Cordages — Specification”, defines the quality framework for ropes made from various materials.
It covers aspects like:
- Construction type (twisted, braided, or laid)
- Material composition (natural fibres like jute, cotton, or coir; synthetic fibres like nylon or polypropylene)
- Diameter uniformity
- Breaking load and elongation limits
- Resistance to abrasion, UV, and chemicals
Under this standard, the BIS testing process evaluates how ropes behave under tension, stress, and prolonged exposure — ensuring reliable performance in demanding applications.
Importance of the ISI Mark for Ropes and Cordages
The ISI Mark is more than just a label — it is a mark of trust and technical assurance.
Key reasons why BIS Certification is essential:
- Compliance and Market Access:
BIS certification is mandatory for ropes used in defence, marine, or construction projects. Without the ISI Mark, the product cannot be legally sold in these sectors. - Quality Recognition:
The ISI Mark assures buyers that the rope has passed all required physical and mechanical tests. - Export Readiness:
Many international clients prefer Indian products with BIS certification, as it aligns with ISO and global quality norms. - Brand Credibility:
Certified products strengthen a company’s reputation in tenders, government projects, and exports. - Consumer Safety:
Ensures that ropes will not fail under load or environmental exposure, reducing accident risks.
Products Covered Under IS 1084:2005
The BIS certification under IS 1084:2005 covers a wide range of natural and synthetic fibre ropes, including:
- Polypropylene ropes
- Polyester ropes
- Nylon multifilament ropes
- Sisal and jute ropes
- Manila and coir ropes
- High-performance blended fibre ropes
Each category undergoes individual mechanical and chemical tests to validate its suitability for use in agriculture, industry, shipping, or domestic applications.
Testing Parameters and Quality Requirements
Before granting the ISI Mark, the BIS-authorized laboratory tests the following parameters:
| Test Parameter | Purpose |
| Diameter & Tolerance | Ensures uniform size and accurate construction. |
| Breaking Load | Measures strength under maximum tension. |
| Elongation at Break | Tests rope’s flexibility and stretch limit. |
| Abrasion Resistance | Checks durability against friction and wear. |
| Water Absorption | Ensures minimal strength loss when wet. |
| UV Resistance | Confirms protection from sunlight degradation. |
These parameters ensure that ropes can perform consistently in marine, industrial, and outdoor environments.
BIS Certification Process for Ropes and Cordages
Obtaining BIS Certification under IS 1084:2005 follows a defined process regulated by the Bureau of Indian Standards:
Step 1: Application Submission
Manufacturers must submit their application on the BIS portal, along with factory details, product specifications, and test reports.
Step 2: Product Testing
Samples are drawn and tested in a BIS-recognized laboratory to verify compliance with IS 1084:2005 standards.
Step 3: Factory Inspection
A BIS officer conducts an on-site inspection to evaluate production capability, raw material control, and in-house testing facilities.
Step 4: Grant of BIS License
Once the factory and product meet all compliance criteria, the BIS issues the ISI license.
The product can then carry the ISI Mark, signifying it meets India’s national quality benchmark.
Documents Required for BIS Registration
Manufacturers must provide the following documents during the BIS certification process:
- Factory registration certificate and layout plan
- Manufacturing process flow chart
- Raw material details and supplier information
- Internal quality test reports
- Sample test reports from BIS-recognized labs
- Authorization letter (if foreign manufacturer)
- Trademark registration (if applicable)
All documents must be accurate and consistent with the factory setup.
Validity and Renewal of BIS Certificate
A BIS license under IS 1084:2005( BIS for Ropes and Cordages ) is valid for two years from the date of issue.
Manufacturers must apply for renewal before expiry, ensuring continuous compliance and factory inspections.
Renewal requires:
- Updated test reports
- Proof of continuous production
- Payment of renewal and marking fees
Timely renewal helps maintain uninterrupted market access and avoids penalties.
Cost Structure of BIS Certification
| Component | Description |
| Application Fee | Paid at the time of online submission |
| Product Testing Fee | Laboratory testing cost for rope samples |
| Factory Inspection Fee | Charges for BIS inspection officer visit |
| License Fee | Payable for the grant of BIS license |
| Renewal Fee | Required every two years for license continuation |
The total cost may vary depending on the rope type, plant location, and testing requirements.
