- Introduction
GB/T 30195—2023 Standard Overview
Pendulum method is a classic method for testing the impact resistance of passenger car tires. GB/T 30195—2023 has comprehensively optimized the test equipment, conditions and procedures. The new standard adds a number of technical requirements on the basis of the old version, including the use specifications of angle sensor, bulge measuring device and image recording device.
Background and significance of standard revision
Comparison dimensions Old version GB/T 30195—2013 New standard GB/T 30195—2023 Scope of application Applicable only to passenger car tires Explicitly covers all pneumatic tire types Key parameter adjustment No clear requirements for pendulum length and impact mass Explicitly stipulate that the pendulum length is (1-830.0±18.3) mm, and the impact mass is (62.0±3.0) kg New Technologies No angle sensor required Added angle sensor with an error of no more than ±0.1° to improve measurement accuracy Test Equipment and Accuracy Requirements
Main test equipment:
- Swing rod system: Strictly controlled length and quality to ensure accurate calculation of kinetic energy
- Angle sensor: Error range of ±0.1° to ensure accurate angle measurement
- Bulge measuring instrument: Accuracy of ±0.02mm, supports high-precision bulge height detection
Test Procedure and Implementation Suggestions
Implementation recommendations:
- Equipment selection:Give priority to pendulum systems and sensor equipment that meet the technical requirements of B.1-B.8.
- Staff training:Ensure that operators are familiar with the test procedures of 6.1 to 6.2, especially the impact angle and energy adjustment.
- Data management:It is recommended to use a digital recording system to store test data for subsequent analysis and traceability.
