Some standard content:
GB/T 2428-1998
This standard is revised on the basis of the national standard GB 2128-81 "Chinese Adult Head Shape Series". This standard is based on the head and face size survey data of more than 11,150 men and women in the national adult anthropometric survey conducted in 1988. The main technical content of this standard is formed through the analysis and statistical calculation of the anthropometric facial size data of small samples. This standard is mainly different from (132428-81) in terms of arrangement: 1. The anthropometric terms and methods used in this standard are based on two national standards, GB3975-83 Anthropometric Terms 3 and GB5703-85 Anthropometric Methods. Some special items are also measured uniformly using industry-specific and anthropological methods to ensure the scientificity and timeliness of the data.
2. In addition to retaining the 29 facial items involved in the original standard, this standard adds 12 new items. 3. In addition to providing statistical data on human head and face items, this standard also provides a two-dimensional distribution table of the main dimensions of the human head and face to facilitate the model design of head and face equipment.
In this standard Appendix A and Appendix I are standard appendices, and Appendix is a suggestive appendix. This standard replaces GB2428-81 from the effective date of H. This standard is proposed by the Ministry of Labor of the People's Republic of China. This standard is under the jurisdiction of the National Technical Committee for Ergonomics Standardization. The drafting units of this standard are: China Institute of Standardization and Information Classification and Coding, Institute of Vertebrate Paleontology and Paleoanthropology, Chinese Academy of Sciences, Institute of Military Equipment of General Logistics Department, 301 Institute of China Aviation Industry Corporation, Tsinghua University. The main drafters of this standard are: Xiao Hui, Hua Donghong, Yang Tingxin, Zhang Zhenbiao, Bi Guozhi, Liu Wei, and Liu Jingmin. Scope
National Standard of the People's Republic of China
Adult face size
Head-face dimenslons of adults This standard only provides basic data on the minimum dimensions of the head and face of adults and a two-dimensional distribution table of the main dimensions.

3.13 Two-dimensional distribution iwa-dimensional distribution1998
Gives the distribution number F(I) of a two-dimensional random variable and any given set in one-dimensional space. For example: randomly select a person from the crowd and measure the maximum length and maximum width of his head, respectively. Then X, Y, constitute a two-dimensional random variable. Its sub-composition is referred to as the two-dimensional distribution of the maximum length and maximum width of the head. 4 Measurement items and dimensions of human head and face

5.1 Setting of one-dimensional distribution table of human head and face dimensions CB/T 24281998
KAoiKAca-
The setting of two-dimensional distribution table of human head and face dimensions is based on the two-dimensional distribution coverage of two sets of data: the maximum length and width of the head, the morphological face length and face width of adult males (18-60 years old) and adult females (18-55 years old); the subfrontal circumference between the top of the head and the back of the occipital point, and the face width. 5.2 Two-dimensional distribution of human head and face dimensions The subfrontal circumference between the top of the head and the back of the occipital point is divided into 10mm grades; the maximum length and width of the head, the morphological face length, and the face width are divided into 5mm grades. They can be rationally merged according to actual needs during use to calculate the coverage. Set the model. 5.3 Two-dimensional distribution table of human head and face dimensions
5.3.1 Two-dimensional distribution table of maximum head length and maximum head width5.3.1.1 Two-dimensional distribution table of maximum head length and maximum head width for men (see Table 3)Table 3 Two-dimensional distribution table of maximum head length and maximum head width for menMaximum head length.mm
Note: This table gives the proportion of the maximum head length and maximum head width in a given population. From the table, we can see that the proportion of the population with a maximum head length of 18 mm and a maximum head width of 150 mm is 7.45%, which means that the proportion of adult men with a maximum head length of 177.5 mm (excluding 177.5 mm) to 182.5 mm and a maximum head width of 147.5 mm (excluding 147.5 mm) to 152.5 mm in the country is .45%. The production ratio of the corresponding products can be determined from this. 5.3.1.2 Two-dimensional distribution table of maximum length and maximum width of female head (see Table 4) Table 4 Two-dimensional distribution table of maximum length and maximum width of female head Maximum width of head, mm

In this standard, the data of head and facial parameters including head circumference, facial length, maximum head length, maximum head width, head shape, head coronal arc and head total height are obtained through direct measurement, and the other 34 items are calculated through a small survey of facial dimensions (sample size: 214 males and 179 females), and the regression equations between the measurement items and the main head and facial parameters are established through stepwise regression (see Table C1 and Table C2).mm

In this standard, the data of head and facial parameters including head circumference, facial length, maximum head length, maximum head width, head shape, head coronal arc and head total height are obtained through direct measurement, and the other 34 items are calculated through a small survey of facial dimensions (sample size: 214 males and 179 females), and the regression equations between the measurement items and the main head and facial parameters are established through stepwise regression (see Table C1 and Table C2).21
