Foam testing is performed across many industries to evaluate the firmness of foam. A universal test machine is ideal for this type of test since it is possible to precisely control the speed of the test, the amount of force applied, or the distance travelled by the compression plate. All of these are critical in properly performing a test on foam. The evaluation of compression strength is known as Indentation Load Deflection (ILD), or Indentation Force Deflection (IFD), but both refer to the same measurement. As a result of this unique industry-specific requirement, United has developed a specialized, single-column foam tester that incorporates a wider base and a longer throat depth to accommodate larger compression plates.
