Operating procedure

Dynamometers

1. Using a drill bit or a similar tool, cut a circular or square notch, depending on the size of the discs, until you reach the basis material. This is intended to define accurately the measuring surface.

2. Stick on the surface to be tested a disc of the appropriate size. To achieve this, you may use a standard epoxy-base quick adhesive.

3. The test consists in drawing out the cut element using the instrument. The result is given in kN.

Extractometers

Ring retaining clamp + shouldered ring

Turnbuckle fork

1. Position the unit on the support to be tested.

2. Using the turnbuckle, secure the fork on the ring.

3. To perform the test, rotate the wheel in the clockwise direction.
