Introduction
The direct method to assess the thermal environment of the vehicle (hot, medium, cold) includes the measurement of various human reactions, and there are three forms. subjective method, objective method
Methods and methods of behavior. Subjective methods use subjective scales to quantify people's reactions to the environment. The objective method refers to the use of instruments or output
Measurement (such as performance measurement) to quantify a person's physical, physiological, or psychological conditions. Behavioral methods quantify or express human response to the environment.
Each method is developed based on basic principles, and the most suitable method form and method combination for thermal environment assessment depends on the evaluation concerned.
Content and transportation environment. This section presents the principles and application methods of using the tested to assess the environmental thermal comfort of vehicles. Evaluation
The most suitable method for communicating the thermal comfort of the tool environment is the subjective method. For the compilation principle of the subjective rating scale, see GB/T 18977, and it is used in the system.
Determine the experimental methods specified in this section. ISO 9886 describes the physiological measurement of the human body, which is beyond the scope of this standard.
This section supplements the standards related to the ergonomics of the thermal environment, and can be used in conjunction with the thermal index applicable to the vehicle environment.

Part 2.Use subjects to evaluate thermal comfort
1 Scope
This part of GB/T 40261 gives guidelines for using subjects to evaluate thermal comfort in vehicles, and specifies a standard
experimental method. This section establishes the general principles of thermal environment assessment and evaluation, not limited to any specific means of transportation. Provisions in this section
Based on whether it can provide people with thermal comfort, the method determines the performance of the vehicle under the conditions of concern, and is used for the development and
Evaluation.
This Part applies to various types of transportation, including cars, buses, trucks, off-road vehicles, trains, airplanes, ships, submarines, cranes, etc.
The cockpit of a car and similar spaces. It is suitable for situations when people are enclosed in vehicles and exposed to the external environment. For exposure
People under external conditions, such as bicycle and motorcycle riders, convertible drivers, and forklift operators without a cockpit, etc., the vehicle speed
Degree and weather will dominate the body's response. The evaluation principles of this section also apply.
This section applies to vehicle passengers and operators whose application does not affect the safe operation of the vehicle.
This section establishes the principles of thermal comfort assessment and evaluation, including the use of test methods and subject experiments. At the same time, this section also mentions
Provides a subjective method for evaluating the comfort of the thermal environment.
This section belongs to the basic ergonomics standards, which is helpful for the development of standards for specific vehicles and products.
