This comprehensive guide provides detailed instructions for the proper assembly, calibration, and operation of the Bally Leather Flexing Tester GT-KC10A. Essential for quality control labs, it ensures accurate testing of flex resistance in leather, coated fabrics, and textiles used in footwear uppers, helping to prevent material failure.

Fabric bursting strength measures resistance to rupture under concentrated load. Three primary test methods are used:

Ball Burst Method (ASTM D3787): Steel ball penetration for textiles/films using testers like GT-C02-2.

Hydraulic Method (ISO 13938.1): Fluid pressure on rubber diaphragm for industrial fabrics via GT-C12A.

Pneumatic Method (ISO 13938.2): Compressed air for breathable materials tested with GT-C12B.
Results are influenced by raw materials, yarn properties,

With the global PPE market’s rapid growth, choosing a professional CE-certified safety glove testing machine manufacturer is critical for data integrity and international compliance. This article explains why CE certification is non-negotiable (ensuring EU safety/quality standards), outlines essential test items (abrasion, cut, thermal protection per EN 388/EN 407), highlights core instruments (GESTER GT-KC28 TDM Cut Tester, GT-KC29 Cutting Tester, GT-C101 Heat Contact Machine), and details how to evaluate suppliers (20+ years of experience, partnerships with SGS/Bureau Veritas, ISO 9001 certification, after-sales support). It also covers the benefits of OEM/ODM capabilities for customized solutions. Ultimately, partnering with trusted manufacturers like GESTER ensures high-precision, compliant testing to protect workers and meet global market requirements.

The Heat Contact Machine GT-C101 is a specialized testing instrument designed for evaluating the heat resistance and thermal protective performance of gloves, protective clothing, and other heat-resistant materials used in high-temperature environments. In industries such as smelting, casting, welding, and glass manufacturing, workers are frequently exposed to intense heat, making accurate testing of contact heat resistance essential for ensuring safety and compliance.

GT-C101 simulates real working conditions by measuring heat transfer delay and thermal transmission under instant contact with high-temperature surfaces. Fully compliant with EN 407, EN 702, and ISO 12127-1 standards, this machine provides precise, repeatable data for manufacturers, laboratories, and research institutions. With high-temperature capability up to 500°C, advanced calorimetry, digital monitoring, and adjustable contact speed, the Heat Contact Machine GT-C101 is an indispensable tool for developing and certifying next-generation PPE and heat-insulation materials.

Slip resistance is one of the most critical performance indicators for modern footwear, especially safety shoes used in industrial and high-risk working environments. Slip and fall accidents frequently occur on wet or smooth surfaces, posing serious risks to workers and consumers. To prevent such accidents and improve product safety, footwear manufacturers widely use professional testing equipment such as Shoe Slip Resistance Tester and Footwear Slip Testing Machine. These devices simulate real walking conditions to measure the coefficient of friction between the shoe sole and various surfaces. This article explores the working principle, features, applications, and industry significance of shoe slip safety tester, explaining why accurate slip resistance testing is essential for footwear safety, product development, quality control, and compliance with international standards.

The ASTM D642 standard defines the test method for determining the compressive resistance of shipping containers, like corrugated boxes, when faced with static compressive forces. This article details the test procedure and introduces the GESTER GT-N02A and GT-N02B Box Compression Testers, which are fully compliant with ASTM D642, ISO 12048, and TAPPI T804. These versatile machines perform destructive strength tests, constant value tests, and simulated long-term stacking tests to ensure your pac

Footwear soles and uppers endure thousands of flex cycles during use, risking premature cracking, delamination, or chipping if material resistance is inadequate. This technical analysis details two critical international standards:

1. ISO 5402-1: Specifies the flexometer method for testing leather flex resistance under repeated bending.

2. ISO 17694: Defines test methods for footwear upper and lining flex resistance, simulating real-world bending stress to assess long-term durability.
