Scope

Scope: This standard specifies the general requirements, vehicle mounting performance requirements, and test methods for emergency safety devices for military and police vehicles in the event of tire blowouts. This standard applies to M and N-class wheeled military and police vehicles. Other wheeled vehicles may refer to it for use. Main technical content: 3. Technical terms and definitions: GB/T 3730.1 and GB/T 15089 define the following terms and definitions, which apply to this document. 3.1. Military and police vehicle: Refers to vehicles used by military and police forces for logistical support. 3.2. Emergency safety device for tire blowouts: An auxiliary device installed inside an inflated tire, which can maintain controllable driving direction, effective braking, and stable steering within a certain driving distance when a tire blows out. 4. Classification: If a vehicle is equipped with one of the following systems, it is considered to be equipped with an emergency safety device for tire blowouts as defined by this standard. 4.1. Class I emergency safety device for tire blowouts: Satisfies all technical requirements specified in this standard. 4.2. Class II emergency safety device for tire blowouts: Satisfies all technical requirements specified in this standard except those stipulated in 5.2.3 for Class I emergency safety devices for tire blowouts. 5. Technical requirements 5.1. General requirements 5.1.1 After the emergency safety device for tire blowouts undergoes high/low temperature resistance, salt spray resistance, mechanical vibration resistance, and durability tests according to the methods specified in Appendix A, it shall not exhibit corrosion, loosening, cracking, or breaking. After the emergency safety device for tire blowouts undergoes aging resistance performance tests according to the methods specified in Appendix A, the change rate of its tensile strength aging performance shall not exceed 10%. 5.1.2 After the emergency
