How to do office chair foot frame test
7. 1 applicability to this test for all the chair foot type rack chassis. 7. 2 test objective the purpose of this test is to assess excessive foot frame under vertical load. 7. 3 test steps a) Demolition of pneumatic rod or castor ( Castor set to keep in place) , generation to obstacles or support. Recommend the use of castor stem to provide support. Obstacles or support should be high enough, in the middle of the test to avoid the foot frame column and/or legs of contact test platform. Will cushion support dismantle machinery and height adjustment from the feet, shelves. Along the vertical direction of horse central column or tapered/horse interface shape fixed model of load test. b) Is applied load, the chair foot leg should be able to move sideways, feet wearing the central column should be able to move along the vertical direction. Obstacles or support should be with the original position of castor/pneumatic rod and similar supporting way, and not hinder its any deflection during testing and/or lateral movement, also can't weaken the rigor of the test. 7. A) 4 test procedure The horse with 11120 N ( 2500 LBS) The force, time lasts 1 min. b) Lift the load. c) The horse again to 11120 N ( 2500 LBS) The force, time lasts 1 min. d) Lift the load, according to 7. 5 to evaluate product acceptance level. 7. The interior structure of 5 accept horse can't sudden big change. Is applied load, the horse can not contact the central column test platform.

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.
