GB/T 5703-2023Basic human body measurements for technological design (English PDF)

Foreword

This document was drafted in accordance with the rules provided in GB/T 1.1-2020 Directives

for Standardization - Part 1.Rules for the Structure and Drafting of Standardizing Documents.

This document serves as a replacement of GB/T 5703-2010 Basic Human Body Measurements

for Technological Design. In comparison with GB/T 5703-2010, apart from structural

adjustments and editorial modifications, the main technical changes are as follows.

---"longitudinal axis of the foot" is added and "styloid process" is deleted from "Terms

and Definitions", and the terms of ten bony landmark points, including "acromion" are

moved to Chapter 5 "Landmarks" (see Chapter 3 and Chapter 5; Chapter 2 of Version

2010);

---The requirements for body posture are added to "measuring conditions" (see 4.1);

---The Chapter "Landmarks" is added, which provides general requirements for landmarks,

as well as definitions and corresponding position diagrams of 21 landmarks (see

Chapter 5);

---The form of the schematic diagrams of anthropometric measurements is modified (see

Chapter 6; Chapter 4 of Version 2010);

---Six basic anthropometric measurements "thumb length", "thumb breadth", "hand

thickness", "hand breadth including thumb", "arm circumference flexed" and "forearm

circumference flexed" are added (see 6.3).

This document modifies and adopts ISO 7250-1.2017 Basic Human Body Measurements for

Technological Design - Part 1.Body Measurement Definitions and Landmarks.

This document makes the following editorial modifications.

---The title of the Standard is modified from "Basic Human Body Measurements for

Technological Design - Part 1.Body Measurement Definitions and Landmarks" into

"Basic Human Body Measurements for Technological Design";

---Appendix A (informative) "Correspondence between ISO 7250-1 Dimension Names

and Numbers and ISO 14738 and ISI 15534 Anthropometric Dimension Codes" of ISO

7250-1.2017 is deleted.

---Appendix A (informative) "Recommended Anthropometric Terminology" is added.

1 Scope

This document provides a description of anthropometric measurements which can be used as a

basis for comparison of population groups and for the creation of anthropometric databases (see

GB/T 22187).

The basic list of measurements specified in this document is intended to serve as a guide for

ergonomists who are required to define population groups and apply their knowledge to the

geometric design of the places where people work and live.

2 Normative References

3 Terms and Definitions

The following terms and definitions are applicable to this document.

imagined center line of the foot, connecting a point between the ankle bones, and the tip of the

second toe

pertaining to the long bones of the hand between the carpals (wrist bones) and the phalanges

pertaining to the anteroposterior (front to back) median plane of the body (midsagittal), or to a

referring to the long bone in the forearm on the little finger side

4 Measuring Conditions and Instruments

A cube, 200 mm on each side, is used for determining the maximal posterior protrusion of a

seated person.

A standard rod, 20 mm in diameter, and approximately 10 cm in length, is used for determining

grip measurements.

Chest and other measurements affected by breathing should be taken during gentle breathing.

5 Landmarks

Most lateral point of the lateral edge of the spine (acromial process) of the scapula, projected

vertically to the surface of the skin. See Figure 1.

Tip of the prominent bone at the base of the back of the neck (spinous process of the seventh

cervical vertebra) in the midsagittal plane and projected posteriorly to the surface of the skin

while the head is held in the Frankfurt plane.

Superior point of the patella (kneecap) projected vertically to the surface of the skin, when the

subject is seated and the feet are parallel with each other.

6 Basic Anthropometric Measurements

Description. Vertical distance from the floor to the acromion. See Figure 24.

Description. Vertical distance from the floor to the most downward-directed point of the iliac

crest (iliospinale anterius). See Figure 26.

Method. Subject first stands with legs a maximum of 100 mm apart and the movable arm of

the measuring instrument is placed against the inner surface of the thigh in such a way that,

when pushed higher, it gently presses against the ischial bone.
