Leather softness test method1
The leather softness test is a routine indicator for checking the comfort and quality of leather. Different indicators have different testing requirements. Here, we will briefly introduce the GB standard as an example. Experiment purpose: To determine the relative softness of leather. Experimental materials: genuine leather, artificial leather. Experimental equipment: leather softness tester. Sample three experimental conditions: experimental temperature: 23±2°C, RH 60±5% experimental steps: 1. Use a test ring with a diameter of 35mm on the test seat of the testing machine; 2. Use the metal plate equipped with the machine to zero the machine dial; 3. Press the sample into the In the test seat; 4. After the sample is pressed in, the pointer on the testing machine will change. After the pointer is stable, record the corresponding value (accuracy to 0.1mm); 5. Take the average value of the three different points tested Note : The distance between two adjacent test points is not less than 15cm. Diameter of the test ring: ∮=35 mm. The diameter of the shrinking ring is suitable for detecting shoe leather. The diameter of the test ring: ∮=25 mm. : ∮=20 mm The shrink ring is suitable for detecting leather for gloves or leather clothing. Report record: The report should indicate the sample form, the value of sample softness and the diameter of the test ring. Example: Sample Name: Brown Leather Quantity: 1 Piece Test Item Results Methods and Conditions Softness Test 1.90mm Temperature: 23±2℃ Test Ring Diameter: ∮=35mm More about Leather Testing Instruments: http://www.standard-groups.com/LeatherShoes/

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.
