3 Terms and Definitions
This document does not have terms and definitions that need to be defined.
4 principles
Under the specified test conditions, wear the clothing sample on the mannequin or humanoid limb equipped with pressure sensors, and maintain a state of balanced free tension.
Stretch. The force value is recorded by the pressure sensor on the surface, and the pressure per unit area of the test site is calculated by using the Laplace formula.
The larger the test value, the greater the pressure per unit area of the human body surface, and the smaller the test value, the smaller the pressure per unit area of the human body surface.
5 Test equipment
Pressure performance tester, including pressure sensor, mannequin (humanoid limb) and automatic calculation and recording device, the specific requirements are as follows.
---Pressure sensor, pressure sensor should use air bag pressure sensor, its thickness should not be greater than 3mm;
The range should not be less than 10000Pa, the resolution is 10Pa; the acquisition frequency is 2s/time, and the error is 0.5%.
--- Automatically calculate the recording device, record and calculate the pressure value per unit area.
---Avatar or humanoid limbs, consisting of head, chest (back), abdomen (buttocks), arms, legs, etc. The keel of a mannequin or a humanoid limb should be adopted
When glass fiber/resin is used, elastic sponge should be used as the filler, and fabric with higher density and smooth surface should be used as the surface layer. avatar or person
The fixing method of shaped limbs should be convenient for testing, and the size should meet the requirements of GB/T 10000, GB/T 1335.1 or GB/T 1335.2.
beg. The requirements for the dimensions of the intermediate mannequin or humanoid limbs are in accordance with Table 1, and the size deviation of the mannequin is ±1.0cm.
