SSG Series Strain Gauge Extensometers - Features

Elastic Modulus Measurements within 1 µm Accuracy - Compliant with Elastic Modulus Measurement Requirements of ISO 527, JIS K 7161, and Class B-2 for ASTM D638

Plastic tensile testing standards, represented by ISO 527, JIS K 7161, and ASTM D638, require high-accuracy displacement measurements.
The SSG series, widely used by plastics manufacturers, public testing institutions, and universities, meets the requirements of these plastic tensile testing standards.

ISO 527, JIS K 7161, and JIS K 7162 test standards require:

  • Extensometer elongation measurements with accuracy within 1% of the measured value.
  • Elastic modulus values based on a secant line or regression line between the two strain points of 0.0005 (0.05%) and 0.0025 (0.25%).

Satisfies Strain Control Requirements of ISO 6892 and JIS Z 2241

ISO 6892 and JIS Z 2241 detail test methods for determining the tensile strength of metallic materials. Included within these standards are two control methods for loading materials until they reach their yield point: a stress-rate controlled method and a constant strain-rate controlled method using an extensometer. ISO 6891-1 defines the strain rate control method as Method A, where testing using this strain rate control method is expected to become increasingly common.

Shimadzu’s SSG series extensometers are ideal for strain-rate control testing according to ISO 6892 and JIS Z 2241.
