This standard specifies test methods for verifying the capabilities of tyres for passenger cars, including terms and definitions for test, test equipment and accuracy, test conditions, test procedure, judgment criterion and test report, etc. Of the test methods presented, only some may be required depending on the type of tyre to be tested (with inner tube or tubeless, diagonal tyre or radial tyre, etc.).
This standard includes:
(1) The bead unseating test, assesses the resistance of the tyre to bead unseating. It applies to tubeless tyres only.
(2) The strength test - test the capability of the tyre structure with respect to braking energy of tread cap.
(3) The high speed test, assesses the capability of the tyre according to its speed symbol.
(4) The endurance test, assesses the resistance of the tyre with respect to service at specified load and speed.
(5) The low pressure test, assesses the reliability of radial tyre at low voltage state with respect to service at specified load, speed and low pressure.
The test methods presented in this standard are not intended for gradation of tyre performance or quality levels.
