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,

Protective glove testing is the core link to verify hand safety protection performance for industrial PPE. This article focuses on the two most authoritative EU mandatory standards EN 388 and EN 407, elaborates on standardized test necessity, complete test items, professional supporting glove testers, result rating rules, and the differences between mechanical risk testing and thermal risk testing. It provides one-stop compliant testing reference for glove manufacturers, third-party testing labs, and safety supervision institutions to meet global CE certification and workplace safety production requirements.

This guide details the 9 critical physical property tests essential for assessing leather quality: Tensile Strength, Tear Strength, Abrasion Resistance, Thickness, Water Vapor Permeability, Water Resistance, Shrinkage Temperature, Color Fastness to Friction, and Bending Strength.

This comprehensive guide explains the 3-Position DIN Abrasion Tester, a rotary drum instrument simulating real-world wear to quantify material abrasion resistance. Learn its working principle (mass/volume loss measurement under controlled friction), key features (touch-screen control, automated dust cleaning), and applications across rubber, tires, footwear, and conveyor belts. Discover compliant standards (DIN 53516, ISO 4649, ASTM D5963), step-by-step operation procedures, and essential mainte

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.

A Programmable Temperature Humidity Chamber simulates environmental conditions to test product durability, stability (like shelf life & ageing), and performance across materials, electronics, automotive parts, food, and pharmaceuticals. This guide explains its five core systems (Control, Refrigeration, Heating, Humidity, Air Circulation) and their functions for precise testing.
