Test items: various masks powerful test items Shandong Derek independently researched and developed a comprehensive testing machine for medical masks and protective clothing, which is widely used in various masks for strong testing items. It meets the testing requirements of national standards and medical standards, and the fully automatic software control system meets the requirements of data storage, printing, and comparison. The imported servo motor is equipped with a precision screw drive system to ensure the stability of the test data. Standards Compliant: GB 19082-2009 "Technical Requirements for Medical Disposable Protective Clothing" (4.5 Breaking strength-the breaking strength of the key parts of the protective clothing is not less than 45N) (4.6 Elongation at Break-The elongation at break of the key parts of the protective clothing should not be less than 15%) GB 2626-2019 "Respiratory protective equipment Self-priming filter anti-particulate respirator" (5.6.2 Exhalation valve cover-the breathing valve cover should withstand axial tension "Disposable mask: 10N, lasts 10s" "Replaceable mask: 50N, lasts 10s") (5.9 Headband-the headband should withstand the tension "disposable mask: 10N, lasting 10s" "Replaceable half-mask: 50N, lasting 10s" "Full-face mask: 150N, lasting 10s") (5.10 Connecting and connecting parts-connecting and connecting parts should bear axial tension "Replaceable half-mask: 50N, lasting 10s" "full-face mask 250N, lasting 10s") GB/T 32610-2016 "Technical Specification for Daily Protective Masks" (6.9 The breaking strength of the mask belt and the connection between the mask belt and the mask body≥20N) (6.10 Expiration valve cover fastness: there should be no slippage, fracture and deformation) YY/T 0969-2013 "Disposable Medical Masks" (4.4 Mask straps-the breaking strength at the connection point between each mask strap and the mask body is not less than 10N) YY 0469-2011 "Medical Surgical Mask" (5.4.2 Mask Belt) GB/T 3923.1-1997 "Determination of Fabric Breaking Strength and Breaking Elongation" (Strip Method) GB 10213-2006 "Disposable Rubber Examination Gloves" (6.3 Tensile Performance) Instrument Technical Parameters: ² Specifications: 200N (standard) 50N, 100N, 500N, 1000N (optional) ² Accuracy: better than 0.5 level ² Resolution of force value: 0.1N ² Deformation resolution: 0.001mm ² Test speed: 0.01mm/min～500mm/min (stepless speed regulation) ² Sample width: 30mm (standard fixture) 50mm (optional fixture) ² Sample clamping: manual (pneumatic clamping can be changed) ² Stroke: 700mm (standard) 400mm, 1000 mm (optional)
