G651 National Standard Shoe Bending Tester: Compliance and Durability Testing
The G651 national standard shoe bending tester is designed to evaluate the flex resistance of shoe soles under repeated bending cycles, ensuring compliance with Chinese footwear regulations. This article outlines applicable standards, key parameters, operating principles, and test methodologies for manufacturers seeking to validate product quality.

Normes applicables

The tester adheres to the Chinese national standard:

• GB/T 20991-2007 (Test method for flexing resistance of footwear soles)

Paramètres principaux

Principe de fonctionnement

The tester uses a motor-driven eccentric wheel mechanism to apply cyclic bending forces to the shoe sole. A load cell monitors applied force, while displacement sensors track bending angles. The system automatically stops at preset cycle limits or when sole cracks exceed predefined thresholds.

Principe d'essai

1. Préparation des échantillons: Secure the shoe to the fixture, aligning the flex line with the tester’s axis.
2. Paramètres paramètres: Define load force, bending angle, and test duration via the control panel.
3. Tests automatisés: The machine flexes the shoe repeatedly, recording real-time force and displacement data.
4. Analyse des résultats: Assess sole cracking, energy loss, and structural integrity to determine compliance with GB/T 20991-2007.

This tester enables manufacturers to ensure footwear meets national quality standards, reducing product defects and enhancing brand credibility. Its precision and compliance with Chinese regulations make it a critical tool for domestic footwear production and quality control.
