When the ice container is full, load the ice for (5 0,5) min
43、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

45、ks The temperature treatment for the test has to be analogue to ice type 2 5.2.4 Procedure 5.2.4.1 Determination of resistance of ice pitons when hammered in Carry out the test at ( 10 3) C. Drive the ice piton into an ice block of type 1, using a vertically guided falling body. Ensure that the ice
46、surface is horizontal and that the ice piton is within 1 of vertical before the first drop. For the first impact, fix the drop height at (375 5) mm above the impact surface of the ice piton. For each successive impact, increase the drop height by the amount the piton has penetrated the ice. Hammer i
47、n the ice piton until the lower edge of the eye is in contact with the surface of the ice. Repeat the procedure, inserting and pulling out the piton slowly from the ice 100 times, without removing the ice core between the individual placements. The piton may be placed in the same ice block several t
48、imes, providing the placements are at least 75 mm apart from each other and from the edges. 5.2.4.2 Determination of screwability of ice screws Fix the ice screw concentrically to the shaft of the holding device by means of the clamp. Store the ice screw and test device at ( 10 1) C for a minimum of
49、 4 h. Place the ice screw on the surface of a type 1 ice block and adjust the holding device to keep the ice screw at right angle to the ice surface. Screw in the ice screw with a continuous contact force of (120 3) N. After a maximum of 10 turns check that the requirements specified in 4.3 are met. Complete the test within 5 min of removal from the conditioning atmosphere. 5.2.4.3 Determination of holding strength of ice anchors 5.2.4.3.1 Testing in radial direction Testing shall
