440 Static Bending Tester

2017-04/440

Provides laboratory measurement of flatwise bending modulus of elasticity (E).

  • Highly accurate
  • Accommodates twist
  • Built-in, stress-free yoke
  • Durable with trouble-free operation

Pneumatically-operated, static weight bending test machine measures deflection at mid-span, by a yoke-mounted dial indicator gauge. Combination pivot and roller load points accommodate warp in the specimen. Adjustable alignment pins, writing table, and storage drawer are included. 

  • Employs a test load and dial indicator to find flatwise bending modulus of elasticity (E) in both North American and metric sizes.
  • Specimen is positioned by hand against adjustable stops and a pre-load is applied. A dial indicator contacts the underside of the specimen at mid-span.
  • Test load of steel weights are positioned with pushbutton-controlled air cylinders and is applied equally at the 1/3 and 2/3 test span locations.
  • Dial indicator is supported on a separate, stressfree yoke structure to eliminate any frame deflection errors that might occur when the test load is applied.
  • Dial indicator withdraws into its protected position simultaneously with the removal of the pre-load from the lumber.
