BIS Certification Consultancy for Fibre Ropes – Polyamide 3, 4, 8 & 12 Strand | IS 4572:2022

Introduction

Polyamide fibre ropes, commonly known as nylon ropes, are high-strength synthetic ropes used where flexibility, resilience, abrasion resistance and reliable breaking performance are important. They are manufactured in different constructions, including 3-strand, 4-strand, 8-strand and 12-strand forms.

Because fibre ropes can be used in demanding applications such as marine operations, mooring, towing, lifting-related applications, industrial handling and other general-service environments, consistent rope construction, linear density, dimensions and minimum breaking strength are important.

The applicable Indian Standard is IS 4572:2022 – Fibre Ropes — Polyamide — 3-, 4-, 8- and 12-Strand Ropes. The standard is the fifth revision and is identical to ISO 1140:2021. BIS Product Manual PM/4572/2, July 2022 provides the certification framework under Scheme-I.

The product is also covered by the Ropes and Cordages (Quality Control) Order, 2024, which makes the Standard Mark under a BIS licence according to Scheme-I compulsory for the listed products, including polyamide 3-, 4-, 8- and 12-strand ropes. The order came into force on 1 April 2025, with a separate commencement date of 1 July 2025 for small and micro enterprises for domestic production.

Qualitance India provides complete BIS Certification consultancy for Polyamide Fibre Ropes, including product assessment, scope planning, grouping, sample preparation, testing coordination, documentation, factory inspection preparation, BIS application filing, licence processing and post-licence compliance.

Important QCO Dates

The 2024 QCO provides:

General implementation: 1 April 2025

Small and Micro Enterprises for domestic production: 1 July 2025.

2026 Amendment

The Ropes and Cordages (Quality Control) Amendment Order, 2026, dated 5 June 2026, amended the 2024 QCO by inserting a temporary provision for goods under Schedule Serial No. 7 made from recycled plastic waste. This specific provision concerns the polypropylene rope entry under Serial No. 7 and therefore does not directly change the IS 4572:2022 polyamide-rope entry at Serial No. 6.

Types of Polyamide Ropes Covered

Type A – 3-Strand Hawser-Laid Rope

This is a three-strand construction in which the strands are laid together in a hawser-laid configuration.

Type B – 4-Strand Shroud-Laid Rope

This construction uses four strands in a shroud-laid arrangement.

Type L – 8-Strand Braided Rope

This is a braided construction made using eight strands.

Type T – 12-Strand Braided Rope

This is a braided construction made using twelve strands.

Why BIS Certification is Important for Polyamide Ropes

A fibre rope’s performance depends on many factors, including construction, fibre/yarn quality, rope diameter, linear density, manufacturing process and breaking strength.

BIS certification helps establish a controlled conformity framework for the product.

For manufacturers and buyers, certification supports:

• Standardized product construction
• Controlled linear density
• Required minimum breaking strength
• Consistent manufacturing
• Proper identification and labelling
• Documented inspection and testing
• Better product traceability.

BIS’s technical overview of IS 4572 specifically notes that the standard establishes requirements for designation, linear density, minimum breaking strength, construction, manufacture, lay, labelling and packaging.

Raw Material Requirements

The current Product Manual states:

No specific raw-material requirement for sampling purposes.

However, the rope is manufactured from polyamide material, and the manufacturer must maintain suitable controls over the input materials used in production.

Important records can include:

• Polyamide yarn procurement
• Supplier details
• Material identification
• Batch/lot records
• Incoming inspection
• Yarn quality information
• Production traceability.

The manufacturer should ensure that its input material and manufacturing process produce rope conforming to the current Indian Standard.

BIS Product Grouping for IS 4572:2022

Grouping is provided under Annex A of the Product Manual.

The licence scope identifies:

• Construction Type: A / B / L / T
• Reference Number: Up to and including a declared reference number
• Type of Stabilization: 1 or 2 in accordance with IS/ISO 9554.

Grouping by Rope Type

Separate samples are required for the different construction types.

Therefore:

• Type A should be considered separately.
• Type B should be considered separately.
• Type L should be considered separately.
• Type T should be considered separately.

Grouping by Size

The Product Manual’s grouping provisions allow the highest size/reference number from each applicable type to be tested to cover the range of sizes under that type, subject to the applicable conditions. This means scope planning is important before sample submission.

Stabilization

The licence scope also identifies:

Type of Stabilization: 1 or 2 according to IS/ISO 9554.

The manufacturer should therefore clearly identify its stabilization arrangement before finalizing the proposed licence scope.

BIS Sample Size for Polyamide Fibre Ropes

The Product Manual specifies:

Sample Size: 10 metres.

This sample is used for the applicable testing programme.

Correct sample selection is important because the certification scope may depend on:

• Rope construction
• Reference number/size
• Stabilization type
• Test capability.

Main BIS Tests for IS 4572:2022

1. Construction and Manufacture

The construction and manufacture of the rope are checked according to the applicable requirements.

This includes inspection of:

• Number of strands
• Rope construction
• Lay
• Manufacturing quality
• Overall workmanship.

2. Lay

Lay is an important characteristic of stranded rope.

The Product Manual specifies routine checking of lay and references IS/ISO 9554:2019.

3. Linear Density

Linear density is an important parameter used to characterize the rope.

The Product Manual references IS 7071:2021 for testing linear density.

4. Minimum Breaking Strength

Minimum breaking strength is one of the most important performance requirements.

The rope must meet the minimum breaking strength corresponding to its construction and reference number.

The Product Manual references IS 7071:2021 for this test.

The current Product Manual lists Physical Properties as part of the applicable test programme under Clause 6.

The exact physical properties and relevant test requirements should be assessed against the applicable standard and rope type.

6. Marking and Labelling

Marking and labelling are included under Clause 5.2.

The manufacturer must ensure that the certified rope is properly identified according to the applicable requirements.

7. Packaging

Packaging is part of the inspection and testing requirements.

The Product Manual includes packaging, invoicing and delivered length as part of the applicable checks.

8. Delivered Length

The actual delivered length of rope is an important commercial and conformity characteristic.

The Product Manual includes delivered length under the prescribed inspection provisions.

Tests That Can Be Completed in One Day

The BIS Product Manual specifically states that:

Construction, Manufacture, Marking and Delivery Length

can be tested according to the applicable requirements.

It also states that:

Linear Density and Minimum Breaking Force can be carried out in a day provided the sample is conditioned.

This is useful for manufacturers planning laboratory schedules.

Conditioning of Samples

Because rope properties can be affected by environmental conditions, appropriate conditioning of the sample is important before determining linear density and minimum breaking strength.

The Product Manual specifically links the one-day testing possibility for these properties to the sample being conditioned.

BIS Testing Equipment for Polyamide Ropes

The Product Manual refers manufacturers and BIS offices to Annex B for the test-equipment list.

For the major tests, the manufacturing/testing facility should provide suitable equipment for:

Length Measurement
