Description Overview Used to measure resistance against repetitive strain for films, composites, and coating films, etc. Flex failure is determined by measuring the pinholes formed in the sample structure. Also called gelboflex. Standard: ASTM F392, "Flex durability of flexible barrier materials". Specifications Flex frequency: 45 per minute Horizontal stroke: 155 mm or 80 mm Stations: 4 Flex angle: 440° (90 mm) or 400° (80 mm) Sample size: 280 mm x 200 mm Sample size (200 by 280 mm) is attached to the flex tester mandrels Flexing action consists of a twisting motion combined with a horizontal motion (compression), thus repeatedly twisting and crushing the film Test set up gives a twisting motion of 440° in the first 90 mm of the stroke and is followed by a straight horizontal motion of 65 mm Speed is 45 cycles per minute Features Plc control and 7 inch touch screen operation 5 standard test modes and 4 test stations Long and short stroke fast switching Protection front cover Condition a, b, c, d and e can be chosen Micro printer Could realize test frequency random setting
