This Standard specifies test methods for verifying the capabilities of tyres for truck and bus, including terms and definitions, test equipment and precision, test conditions, test procedure, judgment criterion and test report, etc. In the test methods given, only some may be required depending on the type of tyre to be tested.

This document describes the laboratory test method for the performance verification of truck and bus tyres, including test equipment and accuracy, test conditions, test steps, judgment rules and test report. Of the test methods proposed, only certain test methods are applied depending on the type of tyre to be tested. This document includes: - Endurance performance test: evaluate the fatigue resistance performance of the tyre through the driving time under the specified load and speed; - High-speed performance test: evaluate the high-speed driving performance of the tyre according to the tyre speed symbol; - Strength performance test: evaluate the structural performance of the tyre by detecting the destructive energy of the tyre crown. The test methods listed in this document are not suitable for grading the performance or quality level of tyre products. This document applies to new pneumatic truck and bus tyres tyres and retreaded pneumatic truck and bus tyres tyres. Other tyres may be tested with reference to this document upon negotiation and agreement of relevant parties.
