ISO 3379  crack strength tester for leather

Introduction

Leather surface cracking tester is used for testing mechanical properties such as leather cracking height, cracking strength, etc. It is suitable for testing the cracking index of vamp, various thin leather and leather surface and the cracking deformation performance of vamp upper.

ISO 3379  crack strength tester for leather

Principle 

A steel ball is pressed against the central part of the fleshy surface of a round leather specimen, and the sides of the specimen are fixed with a clamp.The pressure and elongation height of the grain surface were recorded when cracks and fractures occurred.
