BIS for Two & Three-Wheeler Wheel Rims - Process & Compliance
In automotive, wheels and rims are very important parts that define the performance capability of a car, the safety capability to handle, and the outlook of the car. Regarding two and three-wheelers, the quality of wheel rims plays a higher criticality as they contribute towards vehicle stability and handling. However, in India, the Bureau of Indian Standards (BIS) has set a particular standard and regulations for light alloy wheel rims used in such vehicles and eligibility for certification. From this blog, the reader can know the documents that need to be produced, the method to be used in testing, as well as the standards that manufacturers need to meet to be accredited under the Quality Control Orders (QCO).

Understanding BIS Certification
Bureau of Indian Standards commonly called BIS is the fourth largest standards body in the world, and it formulates and implements standards in the country apart from providing certification that can assure the quality of the product. The BIS certification is compulsory for some products to protect the health and safety of the people and prejudice practice, conserve the environment, etc. There is a specific requirement for automotive wheel rims and these must conform with certain Indian Standards.
Quality Control Orders (QCO)
The QCOs of automotive wheel rims were prospectively put into practice to guarantee the products fit the safety and quality parameters. The relevant standard for light alloy wheel rims is IS: 16192 (Part 1) was enacted on June 22, 2023, as a law. This standard provides a detail on the method of tests and the performance requirement that needs to be met to acquire BIS certification.

Testing Methods for Light Alloy Wheel Rims
To ensure compliance with IS:16192 (Part 1), before placing on the market, manufacturers of light alloy wheel rims must go through a number of tests that are very stringent.
Step 1: Rotation Bending Fatigue Test
This test checks the rim capacity to bend stress in using it on other equipment.
Procedure: The rim stone has to endure a continuously acting bending moment while it is revolving a certain number of rpm.
Criteria: Thus, the rim of the tire should be able to sustain at least 10⁵cycles without the growth of deleterious cracks or large deformation.
Step 2: Radial Load Durability Test
This test gives an indication of the ability of the rim to withstand vertical loads in a progressive manner.
Procedure: The rim fits a tire, and then is loaded radially.
Criteria: The rim should be able to endure 5×10⁵ cycles without having to deform or become loose.
Step 3: Radial Impact Resistance Test
This particular test shows how the rim reacts to shock loads that may get exerted on it.
Procedure: A weight weight of a specified mass is dropped from a specific height onto the rim of the specimen.
Criteria: Cracks as well as air leakages after impact test should not be of any dangerous nature.
Step 4: Torsion Moment Test
This test is designed to understand the ability of the rim to cope with twist forces.
Procedure: A machine applies torsional moments on it, especially on the rim of the product.
Criteria: In this test, the rim has to withhold 5 ×10⁵ cycles without undergoing any significant deformation.
Step 5: Air Leak Test
This test confirms whether the rims of tubeless tires are sealed.
Procedure: The rim is pressured with air at least to 300 kPa and any loss of air is identified.
Criteria: During this test, it is important for no air to be let through the rim at all.
Performance Requirements
After conducting these tests, light alloy wheel rims must meet specific performance criteria:
- Durability Against Bending Moment: Fatigue testing also has to make sure that no crack or anything that could be considered abnormal looseness has to be seen in the test sample.
- Radial Load Durability: Similar considerations apply, it is expected that no large deformation should happen after radial load testing.
- Impact Resistance: Rims should not have dangerous cracks or air leaks after the impact tests and they should stay fully intact.
- Torsion Moment Resistance: After torsion testing, there should be no deformities that were not present in the rims of the test sample.
- Airtightness: Specifications of a tubeless tire rim must hold air pressure and be leak-proof.
Additional Considerations
There are some additional considerations that you may consider
Metallurgical Testing
- Beyond mechanical tests, metallurgical evaluations are crucial for assessing material properties:
- Chemical Composition Analysis: Checks that meet the set alloy type.
- Microstructure Analysis: Covers the structural aspects of granules and imperfections that may impact the performance of the granules.
Hardness Tests: Often performed in order to use, for instance, the Brinell or Rockwell test to measure the material’s hardness.
Dimensional Measurements
Accurate dimensional measurements are vital to ensure compatibility with tires:
- Specifications of rim measurements incorporate the outer rim diameter, width, and outer rim flange dimensions.
- The roughness surface evaluations thus perform vital tasks of pointing out problems that may affect tire seating or sealing.
Compliance Process Overview
The process for obtaining BIS certification involves several key steps:
- Documentation Preparation: Finally, bring all the documents mentioned above for the respective course of study.
- Application Submission: Pay the application fees & send the application form through the BIS online portal form for registration.
- Scrutiny of Application: BIS makes some sustainability reviews on submitted papers with the aim of judging their thoroughness and accuracy.
- Audit of Manufacturing Premises: An inspection team pays a visit to the manufacturing facility in order to check whether the set standards have been complied with.
- Sample Collection and Testing: The samples are taken for testing to laboratories accredited by the BIS, that is Bureau of Indian Standards.
- Grant of License: After all the stages have been completed, BIS issues a license that enables manufacturers to use the ISI mark on the products that meet the set criteria.
Fees for BIS Certification
The government-approved fees for BIS certification of molded solid rubber soles and heels under IS 16192:2014 are as follows:
| Category | Fee (INR) |
|---|---|
| BIS Application Fees | 9000 |
| BIS Marking Fees | Micro Scale-79,800 |
| Small Scale-19,9500 | |
| Medium Scale-3,19200 | |
| Large Scale-39,9000 |
NOTE: BIS testing charge fees are subject to changes from time to time depending on the circulating governments’ policies on fee structure.
Thus, it is recommended to visit the official site of BIS or consult with a BIS registration consultant like Professional Utilities.
