BR-PV-UMT Universal Material Tester Implementation of standards: UL 1703-2008 "Accelerated Aging Test" GB/T 2790 and GB/T 2791: EVA "Peel strength test" GB 18173 and GB 12952: TPT "Stretching and tear test" GB/T 2059: Solder Strip "Tensile strength and elongation epigastric test" ETAG 002-2000: Silicone Sealant "bonding test"
Max. test force range: 500N (Provide a 200N sensor backup) The biggest test force value: 1%~100%F.S. Test accuracy: better than the indication force 1% Beam displacement measurement resolution: 0.01mm Deformation measurement accuracy: ±1% or better Deformation measurement resolution: 0.01mm Adjustable speed range: 1~500mm/min Effective tensile space: ≥600mm Tester dimension: 600mm×400mm×1650mm Microcomputer control: with computer and software Software functions: data storage function, automatically generate statements format… Note: for EVA test, automatic calculation after the average 100mm to peel strength within.
The application in UL 1703Accelerated Aging Test:
Minimum tensile strength
