For the purposes of this European Standard, the following terms and definitions apply.
anchoring device intended for repeated use after installation, that is inserted into a drilled hole in the rock andheld in place by gluing, or expansion forces, or positive locking, and with an attachment point for a connector(in accordance with 3.1 of EN 12275:1998).
Install the rock anchor into a concrete block in accordance with the information supplied by themanufacturer. If rock anchor bodies are supplied without hangers, attach a hanger in accordance with the in-formation supplied by the manufacturer.If hangers are supplied without bodies, attach the hanger to a fixedstructure in accordance with the information supplied by the manufacturer.
Attach the concrete block to the tensile testing machine using clamps at a distance a ≥ installedlength l + 5 % away from the axis of the rock anchor (see Figure 3).Apply an axial load to the rock anchorusing a pin with a diameter of (10 ± 0,1) mm in the eye at a rate of (35 ± 15) mm/min, increasing the load to(8±0,25) kN then reducing the load to less than 0,5 iN.Apply this loading a total of ten times within 10 min.Again apply a load, increasing it until failure or until the rock anchor is pulled out of the concrete block.
Install a new rock anchor into a new concrete block in accordance with 5.3.2.1.Attach the concrete block to the tensile testing machine using a support, and a clamp at a distance a ≥ installed length1+ 5 % away from the axis of the rock anchor (see Figure 4). Apply a radial load to the rock anchor using a pinwith a diameter of (10± 0,1) mm in the eye at a rate of (35±15) mm/min, increasing the load to (8±0,25) kNthen reducing the load to less than 0,5 kN.Apply this loading a total of ten times within 10 min. Again apply aload, increasing it until failure or until the rock anchor is pulled out of the concrete block.BS EN 959 pdf download.
