How is the basic Goodrich Flexometer Test performed – Heat-Build-Up and Blow-Out Tests?
Usually, the test is performed with 30 Hz and a static load of 1 MPa, followed by a dynamic stroke of 4.45 mm. This test is called the Heat-Build-Up (HBU) test. If the static load is raised to 2 MPa, the test is known as a blow-out (BO) test.
Advancement to the basic flexometer: GABOMETER®
The GABOMETER® is superior to the Goodrich flexometer since you can measure not only the heat build-up at the surface but also inside the rubber sample by using a needle thermocouple. The GABOMETER® can be upgraded to a complete DMA for measuring viscoelastic properties in compression mode.
