De-Mattia Flex Tester
The apparatus consists of pairs of flat grips of each pair being positioned vertically above the other. One of the grips of each pair shall be capable of a reciprocating motion in a vertical plane; the rate of movement of the reciprocating grip being 5.0 + 0.2 Hz. Each pair of grips are so positioned that they are 70+1 mm apart when in the open position and 12.5 + 0.5 mm apart when in the closed position.
The specimen shall be taken from the selvedge and at least 1 m from the beginning or end of the piece. The sample should be cut in a way that it gives the maximum representation of the fabric to be tested. The standard specimen should be a rectangular one about 125 mm long and 37.5 + 1 mm wide. In every series of test, cut six test specimens, three parallel to the longitudinal direction and three parallel to the transverse direction. Please note that there is no test pieces contain the same threads of fabric in the direction to be tested.
Angle of oscillation of grips : 57.15 ± 0.1
Flexing frequency : 300 ± 10 cycles/minute
Maximum distance between each set of the opposite grips : 75 ± 2
Dimensions of test specimens : 125 x 37.5 mm
Maximum number of test Specimens : Six that can be tested At one timeMotor : ¼ HP single –phase 230 volts AC
