Test principle and use method of Martindale Abrasion Tester
1. Machine model: G235 2. Product name: Martindale abrasion resistance and pilling tester 3. Standard: ASTMD 4970; ISO12945.2; GB/T4802.2/13775/21196.1/21196.2; ASTMD4966; ISO 12947; FZ/T 20020; BS3424-24/5690; ISO 12947.1/12947.2; M&S; P17/P19/P19C; NEXT 18/18a/18b; ISO5470-2; IWTO-40; JIS L10968.17.5 MethodE; Woolmark TM112/196; BS EN 388/530/13770; ISO20344 Abrasion resistance and pilling performance of a kind of fabric 5. Test method: The test sample is rubbed with a standard friction cloth under the specified pressure, and the abrasion resistance of the sample is evaluated after reaching a predetermined number of rotations. 6. Product features: 1. Number of stations: 9, which can significantly improve the test efficiency; 2. Active sample fastening components: a friction sample can be taken out at any time without affecting other samples, improving the testing flexibility; 3. , Friction count range: 0~999999 times, can adapt to the test requirements of different wear-resistant materials and standards; 4. Stroke: horizontal 60.5±0.5mm, vertical 24±0.5mm, which can adapt to the needs of different sizes of materials to be tested; 5. Two effective friction diameters: can be selected according to actual needs 6. The relative movement speed of the gripper and the grinding table is adjustable: 20-70r/min 1. Friction resistance test The circular fabric sample is fixed on the grinding table, and the friction test is carried out with the friction head fixed with the standard friction cloth. There are three evaluation methods: the determination of sample breakage, the determination of mass loss, and the evaluation of appearance changes. 2. Pilling test The pilling test method used in Martindale was developed with EMPA. The test is suitable for knitted and woven fabrics (woven from spun yarn). Use a testing instrument to simulate the pilling that occurs in normal wear. Under slight pressure, rub the sample mounted on the sample holder and the fabric on the grinding table with each other in a certain geometric pattern, and then rub the ground sample. Compared with the standard sample photo. According to the type of the tested sample, it can be simply divided into: knitted pilling review sample photo, woven fabric pilling review sample photo. And according to the eye redness of pilling, it is divided into five grades 5-no pilling? 4-slight pilling? 3-moderate pilling 2-severe pilling 1-very serious pillingMore about Martindale wear test : http://www.standard-groups.com/TextileGarment/

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.
