4.4.4.1 The conductor shall have good insulation properties. Electrical equipment and conductors shall be able to withstand the ambient temperature and humidity, especially the temperature in the engine compartment and the 4.4.6.1 The materials within 100 mm around the exhaust system, high-voltage electrical equipment and other obvious heat sources shall be able to withstand the high temperatures that may be encountered, otherwise they shall be
effectively shielded, to prevent grease or other combustible materials from coming into contact with them.
4.4.6.2 The flame-retardancy of the interior decoration materials of the bus is tested according to the method of GB 8410-2006; its horizontal burning speed shall be less than or equal to 70 mm/min.
4.4.6.3 The engine compartment shall use sound insulation and thermal

4.4.7 Fire monitoring and fire extinguishing facilities
4.4.7.1 Buses shall be equipped with an alarm system that can monitor the high temperature or smoke in the compartment.
4.4.7.2 If the engine compartment is located behind the driving area, a temperature alarm system shall be configured, to issue an alarm when the temperature is too high in the engine compartment and other cabins equipped with gas/fuel heaters.

intercommunication staircases or 1 intercommunication staircases and 1
half staircase;
b) On a class III double-deck bus, if there are more than 30 passengers on the upper deck, there shall be at least 2 intercommunication staircases or 1 intercommunication staircases and 1 half staircase.
4.5.2 Exit location
4.5.2.1 The service door shall be located on the right side of the bus, at least one of the service doors shall be located on the front half of the bus. However, the following doors can be set:
a) A door (non-service door) for wheelchair passengers is provided in the rear or side wall;
b) A service door is set in the rear wall, which can be used by passengers when special needs;
c) For buses designed for passengers to get on/off from left side, such as those that only need to get on/off from left side due to the location of the platform, service doors can be provided only on the left. For buses
designed for passengers to get on/off from both sides, such as the buses that need to run not only along the dedicated lane for public bus as
provided along the central lane of the road but also along the ordinary road, it may set one or more service doors at the left side; however, it shall ensure that when the service door at one side is opened, the service door at the other side shall be reliably locked simultaneously;
d) A service door is provided in the back of the class A or class B bus. 4.5.2.2 If the passenger area S0 is greater than or equal to 10 m2, the two service doors specified in 4.5.1.1 shall be provided separately. For single-deck buses (except for class A, class I, and class II buses whose service doors are on the left), the distance between the horizontal vertical planes passing through the center of the area of the two doors shall be greater than or equal to 40% of the total length of the passenger area. For double-deck buses, if the two doors are on the same side, the distance shall be greater than or equal to 40% of the total length of the passenger area at lower deck or 25% of the total length of the bus. If they are not on the same side, it does not need to meet this requirement. If there are double doors in the two doors, it shall be measured between the two farthest doors. For articulated buses, if the distance between two doors of different rigid sections is greater than or equal to 40% of the total it can still be opened from inside the vehicle.
4.5.4.2 The height of the door opening device outside the vehicle to the horizontal ground (at no load) shall be less than or equal to 1800 mm; the distance from the outer edge of the door shall be less than or equal to 500 mm or on the door.
4.5.4.3 For hinged or pivoted single-leaf hand-operated service door, when the bus moves forward, the opened door shall tend to close when it touches a stationary object.
4.5.4.4 If the spring-loaded lock is used for the manually controlled service door, it shall be of two-stage type.
4.5.4.5 When the service door is closed, there shall be no mechanism on the inside of the door to cover the step. The door operating mechanism and other devices installed on the inside of the door can invade the concave part of the step, but the intrusive part shall not become an additional floor that the passenger may stand on; meanwhile the mechanism and device shall not be hazardous to passengers.
4.5.4.6 The driver shall be able to observe the situation of passengers near the inside and outside of each non-automatically controlled service door on the seat. For class I double-deck buses, this requirement also applies to the inside of all service doors and the vicinity of each intercommunication staircase on the upper decks. For service doors on the rear wall of class A and class B buses, if the driver can observe a person of 1.3 m tall at a point 1 m behind the bus, it meets this requirement. For the service door on the articulated bus behind the hinge, it shall not be observed only with the mirror. If it is not directly observable, optical or other auxiliary devices shall be installed.
4.5.4.7 Under the conditions of normal use, when the service door is opened inwards, its structure shall ensure that the opening movement will not harm the passengers. When necessary, appropriate protective devices shall be installed. 4.5.4.8 If the service door is adjacent to the toilet or other inner doors, it shall be able to prevent misuse. This requirement does not apply to service doors that can be automatically locked when the vehicle speed exceeds 5 km/h. 4.5.4.9 The service door located in the back wall of class A and class B buses shall have an opening angle of greater than or equal to 85?? and be automatically kept in the open position.
4.5.4.10 Any open state of service doors shall not prevent passengers from reaching or using emergency exits, except for buses with a length of less than 7 m and sliding doors.
4.5.5.3 For each driver operated service door, the driver shall be able to operate it with manipulators on the seat. The manipulators (excluding manipulators operated with feet) shall be clearly marked and distinct from other signs. 4.5.5.4 Each power-controlled service door shall be able to activate a visual warning device. The driver shall be able to clearly see this warning in the normal driving position and in any lighting environment, to remind that the door is not completely closed. This warning device shall give a signal between the fully open position of the rigid structure of the door and 30 mm from the fully closed position. Multiple doors can share a warning device. However, the front service door that does not meet the requirements of 4.5.5.6a) and 4.5.5.6b) may not be equipped with such warning device.
4.5.5.5 The control part for the driver to open and close the power-operated service door shall be able to enable the driver to move the service door at any time during the door closing or opening process.
4.5.5.6 The structure and control system of the power operated service door shall ensure that the passengers are not injured or pinched by the door when closing the door. If the following two requirements are met, this provision is met: a) At any of the measurement points as described in Appendix C, the
clamping force when the door is closed shall not exceed 150 N, otherwise the door shall be automatically fully opened again (except for
automatically operated service door), meanwhile kept in the open position until the door closing control is operated. See Appendix C for the test method. The peak force can be higher than 150 N for a short time, but
shall not exceed 300 N. Re-opening system can be checked by a test bar
which has a cross-section height of 60 mm, a width of 30 mm, a radius of 5 mm.
b) When the passenger's wrist or finger is caught by the door, one of the following conditions shall be met:
1) The door shall be automatically reopened to fully open (except for
automatically operated service door) and kept open until the door
closing control is operated.
2) The passenger's wrist and fingers can be easily extracted without injury. This requirement can be checked by hand or test bar (section height 60
mm, width 30 mm, fillet radius 5 mm). The thickness of the test bar...
