Test methods for footwear insoles - static compression deformation
1 Scope
This document describes a test method for static compression deformation of insoles:
This document is applicable to various microporous foam insoles with base materials such as ethylene-vinyl acetate copolymer (EVA), polyurethane (PU) foam, etc:
Determination of state compression deformation:

3 Terms and definitions
The terms and definitions defined in GB/T 2703 and below apply to this document:
3:1
Compression deformation compressionset
The sample deforms after being compressed by an external force: When the external force is removed, the geometric dimensions change in the direction of the force:
4 Principles
When the insole is compressed by an external force, its microporous foam base material will deform in the direction of the force: When the external force is removed, the microporous foam base material still cannot
Restore to original geometric dimensions: In this method, after the insole is statically compressed under a certain pressure and a certain period of time, the insole is produced in the direction of the force:
The geometric dimensional change rate is used to evaluate its compression deformation performance:
5 Instruments and Equipment
5:1 Static compression tester, the structural diagram is shown in Figure 1, and should meet the following requirements:
---Indenter, the diameter is (25±0:5)mm, (30±0:5)mm, (40±0:5)mm optional, the chamfering radius of the edge of the indenter is (1:0±
0:25)mm:
---Manually lift the table to realize the adjustable distance between the indenter and the test platform from 0mm to 50mm:
---The test load is (10±0:1)kg, (15±0:15)kg, (20±0:20)kg, (25±0:25)kg, (30±0:30)kg optional:
---Testing platform, the table top is flat and has no elasticity:
---Static compression tester with constant temperature and humidity function: The temperature fluctuation of its constant temperature and humidity chamber is controlled at ±1℃, and the relative humidity wave
Mobility is controlled at ±5%:
