Usage, precautions and maintenance of American standard washing machine
How to use the American standard washing machine and precautions: 1. Sort the fabric before washing to avoid affecting the test effect 2. Add detergent to the bottom of the enamel liner (select different detergent types and dosages according to different test standards) 3. Add test fabrics (Remember not to exceed the maximum load capacity) 4. Select the program (please choose different test programs according to different test standards) 5. Select the load capacity (four choices of small, medium, large, and super large) 6. Select the washing temperature (different samples Choose different washing temperature for the type, please refer to the corresponding AATCC standard test method for details) 7. Press the Start knob to start the washing process. (Because the system automatically checks the load balance, there will be a 2-3 minute delay in water filling, which is normal) American standard washing machine maintenance: 1. Regularly replace the water inlet pipe 2. Choose an appropriate amount of detergent according to the standard, and do not use excessive detergent 3. Appropriate use of warm water and hot water washing procedures, do not only use cold water. 4. Keep the lid open between use to keep the inside and outside of the washing machine dry 5. Please clean the washing machine after use to extend its service life. Article source: Standard Group (Hong Kong) Co., Ltd.

Cut resistance is one of the most critical performance indicators in personal protective equipment (PPE) testing, directly affecting worker safety in high-risk industries such as metal processing, machinery manufacturing, and emergency rescue. The TDM Cut Test Machine GT-KC28 plays a vital role in accurately evaluating the cut resistance of PPE products, including gloves, protective clothing, footwear materials, composite materials, rubber, and industrial textiles.
By adopting high-precision force control systems, intelligent data processing, and stable transmission technology, the GT-KC28 TDM Cut Tester can accurately measure the critical cutting force of materials and ensure excellent repeatability and comparability of test results. Its user-friendly touch-screen operation, comprehensive data storage, USB data export, and built-in thermal printer greatly improve laboratory efficiency and data traceability.
The TDM Cut Test Machine GT-KC28 fully complies with major international and national standards such as ISO 13997, EN 388, ASTM F2992/F2992M, ANSI/ISEA 105, and GB 24541-2022, making it a reliable solution for PPE manufacturers, third-party testing laboratories, and research institutions. Through precise and standardized cut resistance testing, the GT-KC28 helps reduce industrial cutting injuries, supports PPE certification across global markets, and ensures that protective equipment delivers reliable safety performance in real-world applications.
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.
