Title:
針貫入試験装置および針貫入試験方法
Document Type and Number:
Japanese Patent JP7351799
Kind Code:
B2
Abstract:
To provide a device and a method for testing a needle penetration that allow a quantitative measurement to be done easily and at site without causing variations in the rate or in the angle of a needle penetration.SOLUTION: The present invention relates to a needle penetration test device 1 and a method for testing a needle penetration using the device 1, the device including: a penetration mechanism 3 having a penetration needle 32 and measurement means 33; a chuck mechanism 4 for holding the penetration mechanism 3; and a passage 21 in which the chuck mechanism 4 can move. The chuck mechanism 4 guides the penetration mechanism 3 to a measurement target surface by moving along the passage 21. The penetration needle 32 penetrates the measurement target surface when the chuck mechanism 4 is guided to the measurement target surface. The measurement means 33 measures a penetration resistance load when the penetration needle 32 penetrates the measurement target surface.SELECTED DRAWING: Figure 1
