BIS Certification Consultancy for Indented Wire for Pre-Stressed Concrete | IS 6003:2010 | BIS & ISI Mark Certification
Introduction
Indented wire for pre-stressed concrete is a high-strength steel wire with a specially formed surface pattern. The indentation improves the bond between the steel wire and surrounding concrete, helping transfer prestressing forces effectively. Such wire is used in prestressed concrete applications where strength, ductility, dimensional accuracy and reliable bond performance are important.
In India, IS 6003:2010 – Indented Wire for Prestressed Concrete specifies requirements for this product. The BIS Product Manual states that certification is operated under Scheme-I of the BIS Conformity Assessment Regulations, 2018 and provides guidance for both existing licensees and manufacturers seeking a BIS certification licence.
IS 6003:2010 is also included in the Steel and Steel Products (Quality Control) Order, 2024. The QCO specifically lists IS 6003:2010 – Indented Wire for Pre-stressed Concrete – Specification and provides for compulsory use of the Standard Mark under a BIS licence. For IS 6003:2010, the QCO specifies implementation with immediate effect.

What is Indented Wire for Prestressed Concrete?
Indented wire is a steel wire manufactured with surface indentations rather than a plain smooth surface.
These indentations are important because they improve mechanical interaction between the steel wire and concrete. In prestressed concrete construction, this bond is important for transferring stresses between the prestressing wire and concrete.
Indented wire can be used in applications such as:
- Prestressed concrete components
- Precast concrete members
- Railway sleepers
- Bridges
- Flyovers
- Concrete beams
- Structural concrete elements
- Other prestressed concrete construction applications
The actual application depends on the product design, specified size and purchaser requirements.
Scope of IS 6003:2010
The BIS Product Manual identifies the following nominal sizes:
8.00 mm, 7.00 mm, 5.00 mm, 4.00 mm, 3.00 mm and 2.50 mm.
The Product Manual also identifies the following geometrical characteristics:
- Elliptical indentation
- Round indentation
- Any other indentation pattern agreed between the manufacturer and purchaser.
The BIS Product Manual specifically notes that different shapes and patterns of indentation are treated as separate varieties because the geometry can affect actual performance when the wire is used for prestressing.
Therefore, manufacturers should finalise both nominal size and indentation shape/pattern before preparing the BIS licence scope.
Is BIS Certification Mandatory for Indented Wire?
Yes. Indented Wire for Pre-Stressed Concrete under IS 6003:2010 is covered under compulsory BIS certification requirements.
The Steel and Steel Products (Quality Control) Order, 2024 specifically lists:
IS 6003:2010 – Indented Wire for Pre-stressed Concrete – Specification
with ITC (HS) codes 72171010, 72179091 and 72179099, and gives immediate effect as the date of implementation.
The QCO requires specified steel and steel products to bear the Standard Mark under a BIS licence in accordance with Scheme-I. BIS is identified as the certifying and enforcing authority.
The current BIS Scheme-I page also lists IS 6003:2010 – Indented Wire for Pre-stressed Concrete under the Steel and Iron Products compulsory-certification framework.

BIS Certification Process for Indented Wire
Step 1 – Product Applicability Assessment
The product is reviewed against IS 6003:2010.
The assessment includes:
- Nominal wire size
- Indentation shape
- Indentation pattern
- Raw material
- Manufacturing process
- Intended licence scope
The Product Manual identifies six nominal sizes and separate indentation varieties.
Step 2 – Product Scope Finalisation
The manufacturer declares the varieties of wire intended to be included in the BIS licence.
The Product Manual specifically states that the licence scope may be restricted according to the manufacturer's manufacturing and testing capabilities.
Step 3 – Product Grouping Assessment
For grouping:
- One wire of any nominal size can be tested to cover all nominal sizes in the proposed scope.
- A separate sample must be tested for each shape and pattern of indentation.
This makes indentation geometry a particularly important part of scope planning.
Step 4 – Documentation Preparation
Technical, factory and quality-control documents are prepared.
Step 5 – Sample Preparation
The BIS Product Manual specifies:
2 Nos. × 1 metre for mechanical tests
3 metres for the relaxation test
50 g drillings for chemical testing.
Step 6 – Laboratory Testing
The samples are tested against the applicable requirements of IS 6003:2010.
Step 7 – BIS Application
The manufacturer submits the BIS application with the required technical and factory documentation.
Step 8 – Factory Assessment
BIS assesses the manufacturing facility, testing laboratory, equipment, quality-control system and production records.
Step 9 – Observation Closure
Any observations or deficiencies identified by BIS are addressed through corrective action.
Step 10 – BIS Licence Grant
After successful conformity assessment, BIS grants the licence for the approved product scope.
Step 11 – ISI Marking
The manufacturer can mark the certified product according to applicable BIS Standard Mark requirements.
Testing Requirements for Indented Wire
Testing is one of the most important parts of BIS certification because prestressing wire must satisfy both mechanical and geometrical requirements.
The BIS Product Manual identifies the following major tests.
Chemical Composition
Chemical composition is checked according to the applicable requirements.
The Product Manual identifies chemical testing for sulphur and phosphorus using the relevant parts of IS 228.
Chemical composition testing is specified once for each cast or heat under the inspection scheme. Where the material is accompanied by a test certificate or is ISI marked, further testing may not be required under the specified condition.
Manufacture
Manufacturing requirements under the standard are checked.
The inspection scheme specifies manufacture-related control for each coil.
Nominal Size and Tolerances
The nominal size and applicable tolerances are checked according to the standard.
Equipment identified includes:
- Micrometer
- Vernier caliper
Ovality
Ovality is also an important dimensional characteristic and is controlled under the applicable dimensional requirements.
Nominal Mass
The mass of the wire is checked according to the applicable provisions.
The Product Manual identifies:
- Weighing scale
- Steel scale
for this measurement.
Geometrical Characteristics
The shape and pattern of indentation are checked because they influence the performance of the wire in prestressed concrete applications.
The Product Manual treats each indentation shape and pattern as a separate variety for licensing purposes.
Tensile Strength
Tensile strength is one of the key mechanical properties of prestressing wire.
The BIS Product Manual identifies a:
Tensile Testing Machine / Universal Testing Machine (UTM)
along with an extensometer and steel scale for tensile-related tests.
The inspection scheme specifies 3 samples from every control unit for tensile strength testing.
If a tensile-strength test fails, the coil from which the sample was drawn is rejected, and subsequent coils are subjected to the specified additional control until the required conformity is re-established.
Proof Stress
Proof stress is tested according to the applicable requirements of IS 6003:2010.
The Product Manual identifies the Universal Testing Machine and extensometer arrangement as relevant equipment.
The inspection scheme specifies 3 samples from every control unit for proof-stress testing.
Ductility / Reverse Bend Test
Ductility is another important characteristic of indented prestressing wire.
The Product Manual identifies:
Bending arrangement with required mandrels
for this test.
The inspection scheme specifies 3 samples from every control unit for the ductility/reverse-bend requirement.
Elongation After Fracture
Elongation after fracture is measured as part of the mechanical-property assessment.
The Product Manual identifies tensile testing equipment, extensometer and steel scale for the relevant tests.
Three samples are specified from every control unit under the inspection scheme.
Relaxation Test
Relaxation is a particularly important characteristic for prestressed concrete wire because the wire must retain the required prestressing force over time.
The Product Manual identifies a dedicated relaxation testing machine and air-conditioning facility.
The inspection scheme specifies:
- 1 sample once a month
- 100-hour relaxation test
- The graph is extrapolated to 1000 hours
- A 1000-hour relaxation test is to be carried out once a year for any one size
The samples should be selected so that all sizes covered by the licence are tested in rotation to the extent possible.
Stress-Corrosion Test
The Product Manual also identifies a requirement for:
Susceptibility to Stress Corrosion – Clause 10.5
where required by the purchaser.
The applicability of this test should therefore be determined based on the purchaser's specified requirements and the applicable provisions of the standard.
