Quanzhou pull vendors would share the constant temperature and humidity box selection method for everyone
Pull vendors would share the constant temperature and humidity box selection method for everyone today instrument co. , LTD for sharing, constant temperature and humidity box selection method for customers to buy suitable products. 1. Selected the use environment of constant temperature and humidity box, especially the reliability test, the test cycle is long, the test object is sometimes worth of military industrial products is very high, in the process of test, test personnel often have to operate or test work around at the scene, and the constant temperature and humidity box must furnish with running safety, convenient operation and reliable in use, long service life, etc, in order to ensure the normal conduct of test itself. Various protection, constant temperature and humidity box warning measures and safety interlock is perfect and reliable, to ensure that the test personnel, subjects the safety and reliability of the product and test equipment itself. 2. Selected test box box size: must be according to the size of the product test to determine the size of the constant temperature and humidity in the box; 3. Selected reasonable is the use of voltage: constant temperature and humidity box power 220 v or 380 v is more than three phase power supply interface, if the temperature in - 40 degrees, and the box dimension in more than 225 l, we suggest four phase 380 v power supply interface, for this to be stable power for the whole of the lab, is good for the life of the equipment itself. 4. Selected air cooling or water cooling: standard generally adopts air cooling is enough, constant temperature and humidity box adopts water cooling is generally large constant temperature and humidity chamber or the rapid rise of box body is various, the cooling chamber, generally hot and cold impact test box adopts water more.

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.
Personal protective equipment must meet specific performance requirements before it can be used in demanding workplace environments. ISO, EN, and ASTM standards provide important test methods and performance requirements for different PPE categories. However, the applicable standard depends on the product, intended application, target market, and specific protection requirements.
This guide explains the role of ISO, EN, and ASTM standards in PPE testing and introduces common requirements for safety footwear, protective gloves, protective clothing, masks, and safety helmets. It also explains how laboratories can select suitable PPE testing equipment according to the applicable test method.
