<p>A device (10) is suggested for elongation detection particularly of small samples (11), featuring two sample holders (12, 13) holding the sample (11) which needs to be tested, stressed and fastened subjected via the sample holders (12, 13) to the stretching force (14, 140). The sample holders (12, 13) feature each time pairs of pins (15, 150; 16, 160) at a certain distance from each other to hold the sample (11) which are located along the line (152, 162) at a right angle to the stretching direction (14, 140); while two device (19) needles (17, 18) for path detection, which can be connected to the sample (11), are gripping at the imaginary pressure points (110, 111) which are located in fact centrally along the each time imaginary line (151, 161)</p> |
