3.1 Basic conditions
3.1.1 The anthropometric terms used in the design should be consistent with GB 3975. 3.1.2 The basic postures and data collection methods used in the design should be consistent with the human body measurement methods of GB5703 3.1.3 The design size of the template adopts the naked human body size with shoes, and its data is consistent with the human body size determined in GB10000. 3.2 Functional size of human body template
3.2.1 According to the distribution of human height scale, the population is divided into three height levels: large, medium and small. The data grouping is shown in Table 1.

Note: 1) The diagram about the angle adjustment range is drawn according to the service function technical measurement system. The angle calibration is shown in Figures 1 to 3: 3) The design of the template waist only shows a coordination relationship, and does not reflect its possible range of activity in a physiological sense! The knee joint is removed from the regular diagram of the template. At this time, the movement of the lower leg will be controlled around the hip joint. 3.4 Design diagram of the human body template

Figure 4 Side view of template joint position Consider the top view and the bottom view According to the provisions of GB/T12985, the human body template of different grades should be selected. 4.1
The size and range of motion of the human body template can be used in various technical diagrams: 4.2
4.3 Select the following hand models according to different requirements for use: Hold the round hand, and the left hand is straight. This indicates the range of grasping in this posture: h
The extended hand indicates the reachable range of the hand: the hand with the fingers pinched together (such as operating a pull switch). 4.4 The range of motion of human joints
The range of motion of human joints marked with angle scales includes the positions that a healthy person can reach without overloading the ligaments and muscles. See Table 2 and Figure 1 Figure 2 and Figure 3.
4.5 The body template can be used in the following aspects:
Assisting technical drawing;
Assisting design;
Assisting demonstration.
