INMETRO 545 Tyre Rolling Resistance Test Brazil
The INMETRO 545 tyre rolling resistance test is a critical measurement in the Brazilian market, ensuring that tyres meet stringent environmental and safety standards. This test evaluates the energy loss during tyre rolling, which directly impacts fuel efficiency and overall performance. The test follows the ISO 6980 standard for rolling resistance of pneumatic tyres, with additional considerations as per INMETRO requirements. This ensures that tyres are not only environmentally friendly but also safe and reliable.
The rolling resistance coefficient (CR) is a key metric in this test. It represents the ratio of the force required to roll the tyre at a constant speed on a flat surface to the weight of the tyre. A lower CR indicates better fuel efficiency, which is crucial for reducing greenhouse gas emissions. This test is particularly important for original equipment manufacturers (OEMs) and tyre retailers looking to comply with Brazilian regulations.
The INMETRO 545 test requires tyres to be tested under controlled conditions that simulate real-world driving scenarios. The testing apparatus used includes a rolling resistance tester, which consists of a steel wheel mounted on an electrically driven carriage. The tyres are inflated to their nominal pressure and placed on the rotating drum at specified speeds. The force required to maintain this speed is measured and converted into the CR value.
The test procedure involves several steps:
- Preparation of the tyre, including cleaning and drying.
- Inflation to the required pressure.
- Mounting on the rolling resistance tester.
- Rotation at specified speeds while measuring force.
- Data collection and analysis.
The results are compared against INMETRO standards, which are stricter than those in other markets. Compliance with these standards ensures that tyres meet not only local regulations but also international expectations for sustainability and performance.
| Key Parameters | Description |
|---|---|
| Test Speed | Typically 5 km/h or 10 km/h, depending on tyre size and INMETRO requirements. |
| Load Application | The tyre is loaded to its nominal load before testing. |
| Temperatures | Temperature ranges from room temperature up to 35°C, depending on the test protocol. |
| Environmental Conditions | Testing occurs in controlled environmental chambers to ensure uniformity. |
The INMETRO certification is a significant milestone for tyre manufacturers. It not only ensures compliance with local regulations but also enhances the reputation of the manufacturer in the Brazilian market. This test is essential for companies looking to enter or expand their presence in Brazil, as it ensures that their products meet the highest standards of safety and environmental responsibility.
