Floating roller test

An alternative to the climbing drum peel test is the floating roller peel test, described in ASTM D3167-76. Direct comparisons cannot be made between the two tests because the floating roller test induces a more severe peel angle than the climbing drum.

The floating roller peel test is used when one adherend is flexible and the other is rigid. The flexible member is peeled through a spool arrangement to maintain a constant angle...

Modern roller presses for the fertilizer and agrochemical industries feature special designs (Figs. 6.6-16 and 6.6-17). Operating parameters are determined during tests with a representative sample of the particular formulation. As for all applications, they include specific pressing force, response characteristic of the floating roller (i.e., in-... 

ASTM D3167-03a Standard test method for floating roller peel resistance. 

A T-peel test is shown in Fig. 27.2. The specimen is usually 1 in. (2.54 cm) wide and is described in Standard Test Method ASTM D1876 [6]. This specimen is symmetrical (both adherends are the same thickness). Other peel test specimens are not symmetrical, such as the floating roller peel test [7] or the climbing drum peel test [8]. The test measures the fracture resistance of an adhesive under conditions in which the adherends may plastically deform. In the tables presented later, the peel strength is given in Newtons per centimeter of width (N/cm) and in tmits of pounds per inch width (piw). The latter is shown in parenthesis. In some cases, the peel strength is derived from climbing drum peel measurements in which the results are presented in torque, in. Ib/in. For pressure sensitive adhe-...

Samples for the floating roller peel test can be a bonded honeycomb type or any adhesive assembly consisting of a rigid adherend and a relatively flexible adherend. Test specimens are typically aluminum with the flexible adherend being 0.025 inch thick and the rigid adherend at 0.064 inch thickness (see Figure 16). Samples are tested in a tensile machine at a crosshead speed of 6 inches/min for three inches of peel distance. Peel strengths are reported in pounds per inch of peel width.
