·The new national standard or official implementation of school bus is divided by length
From February 15th to 18th, the 2012 Beijing School Bus Development Seminar and International School Bus Exhibition jointly hosted by China's Care for the Next Generation Committee and the Ministry of Education of the People's Republic of China was held at the Beijing National Convention Center Exhibition Hall. According to the news from the seminar of the school bus show, the new national standard of the school bus will be officially implemented in March. Recently, the second edition of the four mandatory national standards, such as the "Technical Conditions for School Bus Safety Technology", has been revised in a large amount compared with the previous "Consultation Draft". The biggest change is that before the cancellation, "flat change" Also known as the "long nose" standard.
Divide the school bus by length
It is reported that after the ten ministries and commissions organized the communication meeting before the Spring Festival, the National Standards Committee has convened technical experts and technical leaders of school bus manufacturing enterprises in Beijing according to the original date, and reviewed four mandatory national standards such as “School Safety Technical Conditionsâ€. And made a lot of changes to the first draft.
In the "Verification Draft", the school bus engine position is no longer clearly defined, but requires that "the front of the special school bus should be equipped with a collision safety structure." In addition, the special school bus type has been re-divided according to the structure and use of the vehicle. Among them, the light-duty special school bus with a length of more than 5 meters and less than or equal to 6 meters is more than 6 meters and less than or equal to 12 meters. It is designated as a large and medium-sized special school bus, which can be used for school buses for children, school buses for primary schools, and school buses for primary and middle school students.
In addition, the specific power of the special school bus (excluding the new energy-specific school bus) (ie, the ratio of the maximum net power of the engine to the maximum allowable total mass of the motor vehicle) is reduced from the original requirement of not less than 10.0 kW / t to not less than 9.0 kW / t; The thickness of the bumper and the height of the floor are no longer clearly defined, but the requirements for the roll test of the passenger car are increased, and the roll stability angle is increased from 32 degrees to 35 degrees. The general principle is that while the safety of the existing school bus is improved, it is necessary to control the cost reasonably and facilitate the popularization of the school bus.
Representatives of participating companies revealed that the bus standards of Yutong's existing specifications are generally different from the industry standards in the “Consultation Draftâ€. According to the revised new “Standardsâ€, mainstream bus manufacturers only need to increase the corresponding costs. Can meet the requirements. In fact, the places where school buses are needed in China are mainly concentrated in the urban-rural junction. Compared with the large-length school buses that were previously circulated, the light-duty special school buses are flexible and more suitable for future market demand.
