Product No.: fs-zs112
Scope of application: This equipment combines vision, tension, heating and servo as a whole, perfectly combines product heating temperature, tension measurement and extension deformation measurement, fully automatically tests and records the deformation process with vision, and collects deformation data. It is applicable to the aging test of products deformed by a certain tension under heating conditions.
1. Scientific name of test piece: small dumbbell test piece, dumbbell shaped cable skin, mainly in black and white translucent, only test 20 mm size test piece;
2. It is necessary to draw a marking line in the middle of the small dumbbell test piece. The white test piece is drawn with a black marking pen, and the black test piece is drawn with a white marking pen.
3. The measured distance is the distance between two marking lines, which is rated 20mm when drawing;
4. If the elongation is within 175%, it is qualified; if it exceeds 175%, it is unqualified if it changes from 20mm to 55mm; if it exceeds 175%, the precision is ± 0.1mm; if it exceeds 175% to 250%, the data will still be recorded; if it changes from 20mm to 55mm to 70mm, the precision can be appropriately relaxed; if it exceeds 250%, the data will not be recorded; Elongation=(final length - original length)/original length * 100%, visual recognition accuracy is ± 0.1mm;
