4 National Standards Such As The Size Of Minors In China Have Been Completed.

When the children's festival comes, everything about children will become the most popular topic.

Many parents have encountered a problem when they buy their shoes and clothes for their children, that is, the number is not uniform. When children are in class, they often feel that the height of desks and chairs is not suitable. Indeed, many children's products in China have lacked relevant standards, because the establishment of standards requires a large number of human data as the basis, and our previous work in this area is relatively weak.

However, we can see from today's article that the departments concerned are stepping up their work in this area. Soon, children's products will have production standards, and parents need not worry about it any more.

Reporters learned from the Chinese Academy of standardization, "61" children's Day eve, the 4 national standards of Chinese Minors, including body size, head and face size, hand size and foot size, have been completed by the Institute.

It is reported that these 4 items standard It is an important task of the national science and technology foundation platform work "national ergonomics basic data and clothing size standard research" project. The 4 criterion is based on the national survey of minors' body size. According to Dr. Zhang Xin, the Institute of basic standardization of the Chinese Academy of standardization, the physical and mental development of minors is not yet mature. Life and consumption are often in a passive state, requiring special attention and care. Due to the lack of national minors' body size data in China, the satisfaction of minors for a long time is far lower than that of adult products. In addition to the pressure of homework, one of the most important reasons is the unsuitable height of desk chairs. If we can scientifically design the products that are commonly used by minors, such as desks and chairs, according to the accurate human body size data, we can avoid these problems to a large extent. The same problem also includes the inappropriate step height, the wide spacing of guardrails, and the unsuitable amusement facilities.

Only by obtaining accurate data on the size of the minors, can designers from all walks of life design all kinds of supplies and facilities that meet their physical characteristics, so that they can be fully considered in various occasions. Juveniles Comfort and safety.

The scope, sample size, number of measurement items and age span of the minors are unprecedented. The target population is our 4 to 17 year old minors. In the Northeast China, the central and western regions, the lower reaches of the Yangtze River, the middle reaches of the Yangtze River, the 6 natural areas of Guangdong and Guangxi Fujian and Yunnan Guizhou Chuan areas, a number of measurement points were selected, with a sample volume of over 2 million. This survey divides minors into 4~6 age group (pre-school age), 7~10 years old (lower primary school), 11~12 year old (primary school senior), 13~15 year old (junior high school), 16~17 year old (high school) 5 age group, and stratified random cluster sampling. More than 150 items are measured, including standing position, sitting size, head size, hand size and foot size. The determination of these measurement items is in addition to referring to relevant national standards and international standards. clothing Leather, furniture, culture and education, sports goods, spanportation, building six industries to investigate the demand for minors' body size data. The relevant standards formulated on this basis can better meet the needs of minors' growth and development and health and safety.

According to the introduction, the international advanced non-contact 3D scanning technology is combined with a small number of manual measurements and two-dimensional image scanning measurements. The non-contact human body measurement technology takes 3D scanner as the main tool. It can acquire a complete 3D human body model of 1:1 in less than 10 seconds. Then the accurate human body size data can be extracted through the measurement software. Compared with the traditional manual measurement, it has an unparalleled advantage in data integrity and reutilization, and it can provide human 3D data manually measured.

Basic data of human body size is an important resource for a country. The size of juveniles reflects the physical status of adolescents in a country, and is also an important indicator for the comprehensive evaluation of the social and economic development of a country. In addition to the 4 national standards, the main tasks of the national basic data and clothing standard research program of ergonomics include the establishment of the national basic database application system for Chinese Minors, the standard body templates for Chinese juveniles, the standard human body computer model for Chinese Minors, the Chinese standard for minors and the prototype of Chinese minors.

It is also understood that, according to the results of the national survey on the size of minors, the Chinese Academy of standardization will also work together with the textile information center and the clothing association to formulate the national standard of "China's minors' clothing size".
