EN ISO 3378 Leather Crack Resistance Tester Grain Crack Index Mechanical Test Machine
Product Introduction
This instrument is suitable for measuring the anti-crack resistance of leather and the grain crack index. It consists of a fixture, cylindrical rollers, and core rods, etc. The fixture rigidly holds one end of the test piece, and is equipped with a cylindrical roller perpendicular to the axis, with a diameter of (25.0 ± 0.5) mm. The position of the roller is adjustable relative to the position of the handle. The core rods meet the standard requirements.
Compliant with standard
EN ISO 3378 Leather - Physical and mechanical tests - Determination of crack resistance and grain crack index
Test principle
Place the leather sample on a known-diameter mandrel and bend it outward under the minimum force required to maintain contact between the leather and the mandrel. This process causes the leather to become fragmented. Rotate the handle by 180° within 5±1 seconds. Observe the fragmentation during the bending process and pay attention to any cracks. If necessary, repeat the test with another mandrel. If the resistance to cracking on a specific mandrel is confirmed, the result will be either pass or fail.
