Automatic Extensometer
SIE-560A/560SA
-
To determine the suitability of a material for an application where it is under load, measuring its elongation is important. Measuring elongation enables determination of the elastic modulus (reversible elongation in the elastic region) by measuring the small initial elongation range, and determination of elongation at specimen failure, by measuring larger irreversible elongation in the plastic region. Shimadzu’s SIE-560A series automatic extensometers accomplish both of these measurements with high accuracy, and provide automated functions that increase testing efficiency and test reproducibility. Ideal for testing a wide variety of materials, including metallic materials, plastics, and composites, the SIE-560A series complies with ISO 527, JIS K 7161, and ASTM D638 standards for plastics tensile testing. In addition, the SIE-560A series supports strain-rate controlled metallic material tensile testing measurements specified in ISO 6892, JIS Z 2241, and ASTM E4
