- BIS certification is an assurance that steel wire which is used for Steel Wire for Nipples is conforming to the standard mechanical, chemical, and dimensional requirements.
- It makes sure that the occurrence of wire breakage, rust problems, and irregular performance of wheels is minimized or avoided.
- Material that is certified becomes a source of trust among bicycle manufacturers, automotive component suppliers, and OEMs.
- BIS certifies that the producer has enough manufacturing facilities, good quality control measures, and trustworthy testing arrangements.
- Acquiring a BIS licence is a way of improving the supplier’s reputation with both local and foreign buyers.
Introduction
Steel wire for spoke nipples is one of the most essential components in the wheels of bicycles, motorcycles, and even light vehicles where the three main characteristics of the wire must be strength, flexibility, and durability. Any deviation of the material can have an immediate effect on the safety of the wheel, its carrying capacity, and the stability of the product in a long period of time.
In order to keep up with quality and standardization, the Bureau of Indian Standards has come up with IS 8564:1977 that defines the requirements for the steel wire used in the production of the nipples of the spokes. BIS certification under this standard is a guarantee for the buyers that the product meets the specified mechanical properties, surface finish, and dimensional accuracy.
For the producers, BIS-approved steel wire is a proof of their conformity with the Indian standards, makes it easier for them to be accepted in the market, and assures them that they are in line with the regulations set by the BIS Act, 2016.Bureau of Indian Standars
What is IS 8564:1977?
IS 8564:1977 is the Indian Standard that defines the technical requirements of the steel wire that is used to make Steel Wire for Nipples for spoke assemblies.
The standards include:
- Chemical composition of steel
- Mechanical properties like tensile strength
- Diameter tolerances
- Surface finish and freedom from defects
- Testing and sampling procedures
Steel wire made according to IS 8564:1977 is mainly the steel wire in the bicycle wheels or in the applications that are similar where there is a requirement for threading, strength, and corrosion resistance to be done consistently.
ISI Mark Certification
According to the ISI Mark Certification Scheme, the steel wire for spokes wire nipples should conform to all the stipulations of IS 8564:1977.
Some of the key features are:
- Defined range of tensile strength
- Restrictions on impurities that affect ductility and strength
- Dimensions for the wire diameter
- The surface should be without cracks, rust, or any harmful defects
- Testing and inspection are obligatory
Only manufacturers have a valid BIS licence can put the ISI mark on the product.
Why is BIS Certification Necessary?
BIS certification is compulsory when products come under the range of notified standards or Quality Control Orders that are set up to regulate the safety and the general consistency of the most important parts. The metal wire which is going to be used for the nipples of the spokes is the factor that will determine the strength of the wheel and the safety of the person riding it.
Mandatory BIS certification:
- Helps to stop bad quality wire that is below standard from being used or sold in the market.
- Make sure that quality is the same for all manufacturers.
- Gives a guarantee to OEMs and end users that the product will not fail them quickly
- Helps to keep the competition level fair between manufacturers
- Means that the product

Step-by-Step Process of BIS Certification
Step 1: Documentation
- Prepare documents for the company and the factory
- Gather product specifications
- Coordinate quality control records
- Make sure documents are in accordance with BIS guidelines
Step 2: Product Testing
- Provide wire steel samples for a laboratory recognized by BIS
- Perform mechanical and dimensional tests
- Get test reports confirming conformity
Step 3: Application Submission
- Submit BIS application through online portal
- Attach documents and test reports
- Carry out BIS fee payment, if applicable
Step 4: Scrutiny & Inspection
- BIS evaluates the documents sent
- An inspection of the factory can be scheduled
- The verification of manufacturing and quality control (QC) systems take place
Step 5: Grant of Licence
- BIS gives out the license number
- Producer is entitled to the use of the ISI mark
- The license is checked from time to time
Documents Required for BIS Certification
| Category | Documents Required |
| Business Documents | Local company registration, ISO certificates, organizational details |
