830 Panel Bending Tester


The Model 830 Panel Bending Tester evaluates finished 4x4 panels based on ASTM D3043 (Method C). The Model 830 (Formerly TECO QL-3) can measure panel deflection in both the parallel and perpendicular direction and takes the panel to ultimate load.

The 830 consists of two rotating posts that produce a load across the panel. The posts are driven by electronically controlled hydraulics. The panel deflection is measured by a digital encoder, eliminating the need for micrometers or other manual measurements. From an operating point of view, one person can easily run the 830 to perform the ASTM D3043 test on a panel. The operator loads the test specimen into the Panel Bender and prompts the computer to run the test. The computer will ask the operator to enter specific information such as the panel thickness and span rating, the producing plant identification, the thickness of the specimen being tested, a control number assigned to the specimen and any other user- or application-specific information. After this data is entered into the computer, the 830 will run the first half of the test. The 830 will pause and release the panel, allowing the operator to rotate the panel for testing in the subsequent position.

When all tests are completed, reports provide the following information:

  • Average Panel Thickness
  • Panel Density
  • Panel Stiffness (EI) in both parallel and perpendicular orientations
  • Ultimate Load at Failure (MOR)
  • Maximum Moment
  • Floating Average of Panel Stiffness Results
