- Round Steel wire for ropes need to have a BIS certification as per IS 1835:1976.
- The standard lays down the features related to chemicals, mechanicals, and galvanising.
- Obtaining the certificate means the product goes through the testing, inspection stages and the ISI mark is used.
- Certified wires are preferred by the buyers and can easily access the market without the risk of legal issues.
- They are also subject to periodic testing and renewal of the license to ensure that they are always in conformity.
Introduction
Once a wire producer in Pune was close to losing a big deal because his round steel wire was of high quality but did not have a BIS certificate under IS 1835:1976. The buyer didn’t accept the delivery stating that it is not in accordance with the mandatory standards. These incidents illustrate how the certification has become indispensable in India’s steel sector. BIS certification confirms that the wires used for ropes are of the required strength, safety, and durability standards. For manufacturers and importers, it is not a matter of choice anymore – it is a necessity for them to have the trust of the public, comply with the regulations, and be able to continue their business. Bureau of Indian Standards
What is IS 1835:1976?
IS 1835:1976 is the Indian Standard that specifies the quality and performance requirements for round steel wires used in rope manufacturing. Eventually, the norm demands that the wires should possess adequate strength, be pliable and have a good quality of a protective layer so that they can be used without any danger in heavy industrial machinery applications such as cranes, elevators, and buildings.
Key Points:
- The standard covers the round wires of a diameter from 0.20 mm to 5.00 mm made of steel.
- The standard may be used for bright (un-galvanized) as well as for galvanized wires, too.
- It mentions the elements of the chemical composition, also the mechanical properties along with the dimensional tolerances.
- Along with this, it also points to the features illustrated by tensile strength, torsion, reverse bend, and zinc coating tests. ISI MARK
- Additionally, correct marking, packing, and product traceability are among the features that BIS certification entails.
Why is BIS Certification Mandatory
BIS certification is a must to make sure that round steel wires for ropes that are made or sold in India are in accordance with the minimum safety, quality, and performance standards laid down by the Bureau of Indian Standards (BIS). It is a way to keep standard quality from different manufacturers and also to safeguard the consumers from the materials of poor quality that can bring about the failure of the mechanical parts in the situations that are decisive.
Key Reasons:
- Legal requirement: The Ministry of Steel has mandated BIS certification as a must by the Quality Control Order (QCO) for round steel wire for ropes under IS 1835:1976.
- Safety assurance: The certified wires are tested for the same, the tests include strength, torsion, and coating, thus the wires can be safely used in heavy-duty applications like cranes, lifts, and mining ropes.
- Market acceptance: Purchasers, mainly OEMs and infrastructure contractors, only accept materials that have the BIS mark in order to fulfill the regulatory and project requirements.
- Quality consistency: The enforced certification ensures that all manufacturers have the same production and testing practices.
- Trade compliance: Those who import without BIS licences and domestic producers are not allowed without a BIS licence. They are in danger of being penalised, having their products rejected, or being banned under the QCO regulations.

Step-by-Step Process of BIS Certification
Step1:Documentation
- Gather factory and company registration certificates.
- Write product specifications and manufacturing flow charts.
- Maintain quality-control procedures and calibration records.
- Ensure all documents align with the relevant Indian Standard (IS).
Step2:Product Testing
- Provide product samples to a laboratory recognised by BIS.
- The testing is carried out according to the standard IS (e.g., IS 1835:1976) cited in the standard.
- Get a real test report with which the product fully complies.
- If there are any non-conformities, you should address them before submitting your application.
Step3:Application Submission
- Submit the online BIS application form on the BIS portal.
- Attach test reports, factory details, and required documents.
- Pay applicable government and processing fees.
- Track application status and respond promptly to BIS queries.
Step4:Scrutiny and Inspection
- BIS officials verify documents and assess the test reports.
- A factory inspection is carried out to evaluate production and testing facilities.
- Inspectors check marking, control units, and record-keeping systems.
- Any observations raised must be resolved for approval.
Step5:Grant of Licence
- BIS issues a licence after successful inspection and verification.
- The manufacturer receives authorization to use the ISI mark.
- Each product batch must meet ongoing compliance and testing requirements.
- Licence is valid for a fixed term and must be renewed periodically.
