Bending capability

The test element shall be secured between the formers so that at least 200 mm of the element

projects below the base of the formers, and the length above is sufficient to bend over the formers.

The free upper length of the element shall be bent at a rotational speed of 12 rpm through an angle of

180° over one former then the other, which means within 5 s to the right and within 5 s to the left. This

cycle shall be repeated three times.
