Figure 1 — Placement length, l 4 Safety requirements 4.1 Design 4.1.1 Ice screws shall consist of a cylindrical or semi-cylindrical hollow body with thread. At the screw head, there is an eye into which a connector can be clipped. Ice pitons shall consist of a cylindrical or semi-cylindrical hollow body and have an eye into which a connector can be clipped. SIST EN 568:2016

a) b) Figure 2 — Attachment point eye dimensions 4.1.3 When tested according to 5.1, the eye shall have an internal diameter of at least 15 mm. See b) in Figure 2. 4.2 Resistance to hammering of ice pitons When tested in accordance with 5.2.4.1, ice pitons shall not show any deformation likely to affect safety, e.g. cracks or separation of components. The impact area of the head shall remain sufficiently intact so as to allow further hammering. NOTE Deformation due to hammering, as occurs with chisels, is not considered detrimental. If the ice anchor has a sling for attachment, which is removable without tools, the sling shall conform to EN 566. 4.3 Screwability of the ice screws When tested in accordance with 5.2.4.2 after a maximum of 10 full rotations of the ice screw the penetration of the following rotation shall be equal to the pitch of the thread of the ice screw. 4.4 Holding strength 4.4.1 Holding strength in the radial direction When tested in accordance with 5.2.4.3.1, anchors shall withstand a force of at least 10 kN in the radial direction, without being pulled out of the ice or breaking. Permanent deformation during the test is permitted. 4.4.2 Holding strength in the axial direction When tested in the axial direction in accordance with 5.2.4.3.2, ice anchors shall withstand a force of at least 5 kN without the hanger breaking or becoming detached. All test samples shall meet the requirement. SIST EN 568:2016

The base of the ice container shall be rigid so that it does not influence the test results. 5.2.2.3 A vertically guided falling body of mass (10 ± 0,02) kg with a flat impact area of 30 mm (± 10) mm diameter of hardness, HV (40) = (800 ± 10) %. 5.2.2.4 A device as shown in Figure 3 to hold a shaft at right angles to the ice surface, the lower end of the shaft having a clamping mechanism for an ice screw, which holds the screw concentrically. A lever is fitted to the top of the shaft for screwing in the ice screw. SIST EN 568:2016

Smooth off any uneven surface of the ice. 5.2.3.2 Type 2: Fill the ice container alternately 50 mm deep with layers of ice grains with a maximum diameter of 10 mm and 250 ml of cold potable water and store it at (– 8 ± 2) °C, for at least 20 h. When the ice container is full, load the ice for (5 ± 0,5) min with a steel plate of mass (100 ± 2) kg, the clearance between the steel plate and the side walls of the container not exceeding 10 mm. The ice block shall be used immediately for testing according to 5.2.4.3.1. The block of ice type 2 can be alternatively replaced by a block of cellular concrete with following characteristics: — Material: cellular concrete — Density: 500 kg/m3 (± 50) kg/m3 — Compressive strength: 4 MPa ± 0,25 MPa — Minimum dimensions: Width: 200 mm, Height: 400 mm, Depth: 250 mm SIST EN 568:2016
