New for 2008, Metriguard has acquired a line of panel testing equipment from TECO and will be manufacturing and servicing this equipment under license from TECO.
The TECO QL-2 Panel Performance Tester is a fully automated, computer-controlled machine designed to perform testing which is consistent with PS 2-07 concentrated static, impact load, and deflection test requirements. The QL-2 is equipped with a "floating bed" that facilitates impact testing. The QL-2 tests panels for:
- Concentrated load and deflection
- Ultimate (failure) load
- Impact load
- Edge-supported configurations
The QL-3 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 QL-3 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 QL-3 will run the first half of the test. The QL-3 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
