Model 642 Bend Fixtures

Model 642 Bend Fixtures are configured to meet a variety of testing requirements. The fixtures have adjustable spans with easy-to-use, permanently attached scales for equal positioning of the rollers. The hardened rollers ensure test result accuracy by reducing undesirable loading and frictional forces on the specimen. All models can be used for both 3- and 4-point tests.

TECHNICAL OVERVIEW

Model 642.001

  • 1, 2, 3, 4, and 5 mm rollers are included
  • Adjustable spans
  • Metric and US Customary scales.

Models 642.01 And 642.10

  • Model 642.01 can be used to meet ASTM D790, ASTM D7264, EN 2746, ISO 14125. The minimum nominal specimen thickness for the 4-point loading setup required by ISO 12125 Method B, is limited to 24 mm for smallest upper span.
  • Model 642.10 can be used to meet ASTM E399, ASTM D7264 and EN 2562. The minimum nominal specimen thickness for the 4-point loading setup required by ASTM D7264, is limited to 24 mm for smallest upper span.
  • Flexible configurations provide either a region of constant stress or a line of maximum stress
  • Adjustable spans
  • Metric and US Customary scales

Model 642.25

  • Well-suited for ASTM E-399 fracture toughness tests
  • Adjustable spans
  • Metric and US Customary scales.
