BIS Certification Consultancy for Geocells | IS 17483 (Part 2):2020 | BIS & ISI Mark Certification

Introduction

Geocells are three-dimensional cellular confinement systems used in civil engineering and geotechnical applications to improve soil stability, control erosion and provide reinforcement. They are generally manufactured from polymeric sheets, with interconnected cells that are expanded at the project site and filled with soil, aggregate or other suitable material.

For slope applications, geocells help confine fill material and improve surface stability. Their performance depends on factors such as cell dimensions, weld strength, material quality, wall thickness, resistance to environmental conditions and long-term durability.

In India, IS 17483 (Part 2):2020 – Geosynthetics — Geocells — Specification, Part 2: Slope Erosion Protection Application specifies requirements for geocells intended for slope erosion protection. The BIS Product Manual operates certification under Scheme-I of the BIS Conformity Assessment Regulations, 2018.

IS 17483 (Part 2):2020 is included in the BIS compulsory certification framework for geocells under the Geo Textiles (Quality Control) Order. BIS's current Scheme-I listing includes IS 17483 (Part 2):2020 under the Geo Textiles (Quality Control) Order, 2024.

An important current update is Amendment No. 3 to IS 17483 (Part 2):2020. BIS issued implementation guidelines in April 2026 and specified 28 June 2026 as the last date for implementation. One of the changes allows testing of either Standard oxidative induction time or High pressure oxidative induction time.

Qualitance India provides end-to-end BIS Certification Consultancy for Geocells as per IS 17483 (Part 2):2020, including product applicability assessment, style and grouping review, documentation, sample preparation, laboratory testing coordination, BIS application assistance and factory inspection preparation.

What is IS 17483 (Part 2):2020?

IS 17483 (Part 2):2020 is titled:

“Geosynthetics — Geocells — Specification Part 2 – Slope Erosion Protection Application”.

The standard specifies requirements for geocells intended for slope erosion protection applications.

The current BIS Product Manual identifies important requirements related to:

Raw material
Construction
Dimensions
Weld spacing
Depth
h/Deq ratio
Texturing
Perforations
Seam weld
Dimensional stability
Density
Environmental stress crack resistance
Carbon black content
Cell-wall thickness
Seam peel strength
Seam weld hang strength
Resistance to oxidation
Retained tensile strength
UV exposure performance
Friction efficiency
Oxidative induction time

What are Geocells?

Geocells are polymeric cellular structures used to confine soil, aggregate or other filling materials.

When expanded, they form a three-dimensional honeycomb-like structure. The cells provide lateral confinement and can help improve the stability of material placed within them.

For slope erosion protection, geocells can be used to:

Reduce surface erosion
Improve slope stability
Confine surface fill
Reduce movement of granular material
Support vegetation-based slope protection
Improve resistance to rainfall and surface runoff

Their exact performance depends on the product design, installation method, filling material and site conditions.

Geocells for Slope Erosion Protection

IS 17483 (Part 2):2020 specifically addresses geocells intended for slope erosion protection applications.

The current BIS Product Manual defines the product as:

“Geosynthetics — Geocells for Slope Erosion Protection Application.”

These products can be used in applications such as:

Embankment slopes
Roadside slopes
Railway embankments
Canal banks
Riverbank protection
Mining slopes
Landscape slopes
Erosion-prone soil surfaces
Infrastructure projects

The actual suitability should always be determined by the project designer based on site and engineering requirements.

Scope of IS 17483 (Part 2):2020

The BIS Product Manual identifies the licence scope using the style of the geocell.

The current scope format is:

Weld Spacing × Depth (in mm)

Examples given by BIS include:

330 × 150
330 × 200

The Product Manual specifically states that the scope of licence is restricted according to the manufacturer's manufacturing and testing capabilities.

Therefore, manufacturers should finalise their desired weld spacing and depth combinations before preparing samples and submitting the BIS application.

Is BIS Certification Mandatory for Geocells?

Yes. Geocells under IS 17483 (Part 2):2020 are included in the compulsory BIS certification framework.

The current BIS Scheme-I listing includes:

IS 17483 (Part 2):2020 – Geocells

under the Geo Textiles (Quality Control) Order, 2024.

The Geocells QCO framework requires covered products to conform to the applicable Indian Standard and carry the Standard Mark under a BIS licence according to the applicable BIS conformity-assessment scheme.

Manufacturers and importers should verify the latest QCO amendments and exemptions applicable to their particular product and business model.

Geo Textiles Quality Control Order

Geocells are included within the broader Geo Textiles Quality Control Order framework.

BIS's current compulsory certification listing places IS 17483 (Part 2):2020 under:

Geo Textiles (Quality Control) Order, 2024 – S.O. 4332(E), dated 03 October 2024.

Earlier geocell implementation material identified 1 January 2024 as the applicable implementation date under the preceding Geo Textiles QCO framework.

Because QCOs can be amended, manufacturers should always verify the current applicable order and notifications before starting certification.

Current Amendment Status of IS 17483 (Part 2):2020

This is an important point for manufacturers.

BIS has issued:

Amendment No. 1 – May 2023
Amendment No. 2 – 2024
Amendment No. 3 – 2026

BIS's April 2026 circular states that Amendment No. 3 was published and that its implementation deadline was 28 June 2026.

The 2026 amendment provides an option to test either:

Standard oxidative induction time
High pressure oxidative induction time

BIS also states that the changes introduced through Amendment No. 3 are relaxations and that no separate evidence of conformity to the amended requirements was required for those changes.

The current Product Manual has also been modified accordingly.

The assessment includes:

Geocell application
Material
Weld spacing
Depth
Cell geometry
Manufacturing process
Proposed licence scope

Step 2 – Style Finalisation

The manufacturer determines the styles to be included in the licence.

The BIS Product Manual uses:

Weld Spacing × Depth

to identify the style.

Step 3 – Product Grouping

Grouping is assessed according to Annex A of the BIS Product Manual.

Step 4 – Documentation Preparation

Technical, manufacturing and quality-control documents are prepared.

Step 5 – Sample Preparation

The current BIS Product Manual specifies:

Sample Quantity: 1 geocell.

Step 6 – Laboratory Testing

The representative geocell sample is tested against the applicable requirements of the standard.

Step 7 – BIS Application

The manufacturer submits the BIS application and required documents.

Step 8 – Factory Assessment

BIS assesses manufacturing, testing and quality-control arrangements.

Step 9 – Observation Closure

Any observations identified during assessment are addressed through corrective actions.

Step 10 – BIS Licence Grant

After successful conformity assessment, BIS grants the licence for the approved product scope.

Step 11 – Standard Marking

The manufacturer can apply the BIS Standard Mark to compliant products according to the licence conditions.

Raw Material Requirements for Geocells

The current BIS Product Manual specifies that the material shall be:

HDPE

and shall conform to the requirements given in Clause 4 of IS 17483 (Part 2).

Compliance can be established through:

Supplier's test certificate
Third-party laboratory test report
NABL-accredited laboratory test report
In-house testing

The Product Manual specifically provides these routes for demonstrating conformity of the raw material.

Proper raw-material control is important because material properties can significantly influence geocell durability and long-term performance.

Construction Requirements

Construction is an important part of geocell certification.

The current Product Manual identifies:

Clause 5.1 – Construction

and requires the manufacturer to implement suitable in-process controls.

Manufacturers should control:

Cell formation
Sheet structure
Weld arrangement
Cell geometry
Joint consistency
Manufacturing defects
General workmanship

Weld Spacing and Depth

The current Product Manual identifies:

Clause 5.2 – Dimensions (Depth and Weld Spacing).

Five samples are recommended for each control unit for these requirements.

The product style is defined by the combination of:

Weld Spacing × Depth

rather than the earlier pocket-size terminology.

BIS Amendment No. 2 specifically modified the definition of Style Number and replaced the terminology of Pocket Size with Weld Spacing. It also replaced tolerances on final expanded-cell size with tolerances on weld spacing.

h/Deq Ratio

The Product Manual identifies:

Clause 5.2.1 – h/Deq ratio

as a routine manufacturing control.

Five samples are required for this parameter from each control unit under the recommended levels of control.

The ratio helps describe the relationship between the cell depth and equivalent cell dimension.

Texturing

Texturing is covered under Clause 5.3.

The manufacturer is required to maintain appropriate controls over the texture characteristics.

The current recommended sampling level is:

1 sample per control unit.

Perforations

Where perforated geocells are manufactured, perforations are controlled under Clause 5.4.

The Product Manual recommends:

5 samples per control unit.

Seam Weld

Seam weld quality is critical because welded joints hold the geocell structure together.

The Product Manual identifies:

Clause 5.5 – Seam Weld

and recommends:

5 samples per control unit.

Dimensional Stability

Dimensional stability is covered under Clause 6.1.

This requirement helps determine whether the geocell maintains its required dimensions under specified conditions.

The manufacturer is expected to exercise suitable in-process controls to ensure conformity.

Density

Density is one of the important material-performance characteristics for geocells.

The Product Manual identifies density testing under Clause 6.2 and refers to methods in:

IS 13360 (Part 3/Sec 10) IS 13360 (Part 3/Sec 11) IS 13360 (Part 3/Sec 12)

Five samples are recommended per control unit.

Environmental Stress Crack Resistance

Environmental stress crack resistance is an important durability characteristic.

The current Product Manual identifies:

ESCR – NCTL

Notched Constant Tensile Load – 400 hours

This test is referenced to IS 16346 and is recommended once every three years, as well as when there are significant changes in:

Raw-material supply
Production technology
Process
Product stabilization

ESCR – 5000 Hours

The Product Manual also specifies a 5000-hour ESCR requirement and recommends testing once every three years, with additional testing following significant changes to raw material, technology, process or stabilization.

Carbon Black Content

Carbon black content is important for polymeric products exposed to environmental conditions.

The Product Manual identifies IS 2530 as the relevant test method.

The recommended testing frequency is:

Once a month

and the Product Manual specifically notes this should be considered for each consignment of raw material used.

Cell Wall Thickness

The current Product Manual identifies:

Post-texturing strip/cell wall thickness at a pressure of 2 ± 0.01 kPa

as a testing requirement.

The applicable test equipment is based on IS 13162 (Part 3) and includes a thickness tester with suitable reference plate, presser foot and gauge.

The recommended frequency is:

Once a week.

Seam Peel Strength

Seam peel strength measures the strength of the welded seam.

The Product Manual identifies:

Seam peel-strength per 25 mm of cell depth

with test method Method B of IS 17369 (Part 1).

This is a routine requirement recommended for:

Each control unit.

The required equipment includes:

Tensile testing machine
Clamps

Seam Weld Hang Strength

This test evaluates the strength of the welded seam under sustained loading.

The current Product Manual specifies:

100 mm of seam weld under a constant dead weight of 72.5 kg for 7 days at 54 ± 2°C.

The recommended frequency is:

Once every three months.

The equipment includes:

Clamps
Tension-testing machine
Circulating-air oven

Resistance to Oxidation

Resistance to oxidation and retained tensile strength are important long-term performance characteristics.

The Product Manual references IS 17360 for this test.

The recommended frequency is:

Once every five years, and also whenever raw material supply, production technology, process or stabilization changes.

Retention of Breaking Strength After UV Exposure

Geocells used outdoors can be exposed to sunlight and UV radiation.

The Product Manual therefore includes:

Retention of breaking strength after UV exposure of 500 hours.

The UV test uses a xenon arc apparatus under specified irradiation and cycling conditions, followed by tensile testing.

The recommended testing frequency is:

Once every five years, with additional testing when specified raw-material or production changes occur.

Friction Efficiency

Friction efficiency is another requirement for geocells used in slope erosion applications.

The Product Manual refers to:

Annex F of IS 17483 Part 1

and recommends testing:

Once every six months.

The relevant test equipment is a Shear Box Apparatus.

Oxidative Induction Time

Oxidative induction time is an important parameter for evaluating the stabilization of the polymer material.

The current Product Manual identifies:

Standard oxidative induction time
High pressure oxidative induction time

and refers to ISO 11357-6.

The recommended frequency is:

Once a year.

The 2026 Amendment No. 3 provides an option to test either Standard OIT or High Pressure OIT.

The equipment is based on a DSC instrument with suitable temperature stability and gas-control arrangements.

BIS Sample Requirement for Geocells

The current BIS Product Manual specifies:

1 geocell

as the sample quantity for grant of licence, change in scope and factory surveillance.

For market surveillance, BIS notes that efforts should be made to procure the required product quantity as far as possible.

Product Grouping for IS 17483 (Part 2):2020

Product grouping is one of the important advantages provided by the current Product Manual.

The BIS grouping provision states that samples of any style, meaning any combination of weld spacing and depth, may be tested to cover the required styles in the licence scope.

For example, where a manufacturer produces:

330 × 150
330 × 200
445 × 200

BIS states that one sample of any style, such as 330 × 150, may be tested to cover all these styles, subject to the applicable provisions.

However, the Product Manual clearly states:

“Scope of licence shall be restricted based on the manufacturing and testing capabilities.”

During licence operation, samples of varieties covered by the licence are to be drawn in rotation to the extent possible.

Control Unit for Geocells

The BIS Product Manual recommends the following control unit:

The entire quantity of geocells of the same style, meaning the same combination of weld spacing × depth, made from the same consignment of raw material under similar conditions in a day.

This definition is important for:

Routine testing
Batch identification
Production records
Traceability
Quality-control planning

Quality Assurance Plan

The current Product Manual expects manufacturers to implement a Quality Assurance Plan containing regular testing and in-process controls.

The manufacturer should:

Define the control unit
