30、protects the climber or mountaineer against falls from a height Note 1 to entry: The safety chain includes ropes connected to the anchors by connectors and to the climbers by harnesses. 4 Safety requirements 4.1 Construction Dynamic ropes in accordance with this European Standard shall be made in a

31、kernmantel construction. Diameter and mass per unit length are relevant characteristics. See test method in 5.3. If the properties of the rope change along its length, for example: diameter, strength, markings, samples from each section shall be submitted for testing. The information to be supplied

32、shall all correspond to the lowest performance section of the rope. 4.2 Sheath slippage When tested in accordance with 5.4, the sheath slippage in a longitudinal direction relative to the core (in positive or negative direction) shall not exceed 1 % (20 mm) (see Figure 3).

35、all not exceed 40 % during the first drop for each test sample. 4.5 Peak force during fall arrest, number of drops 4.5.1 Peak force in the rope When tested in accordance with 5.6, the peak force in the rope, during the first drop, for each test sample, shall not exceed: 12 kN in single ropes (single

36、 strand of rope); 8 kN in half ropes (single strand of rope); 12 kN in twin ropes (double strand of rope). 4.5.2 Number of drops When tested in accordance with 5.6, each rope sample shall withstand at least 5, for twin ropes at least 12, consecutive drop tests without breaking. 5 Test methods 5.1 Te

37、st samples A test sample with a length of: 40 m for single and half ropes, 80 m or 2 40 m for twin rope; shall be available for the tests. Carry out the tests in accordance with 5.3 on an unused test sample. Carry out the tests in accordance with 5.4 on two unused test samples with a length of (2 25

38、0 10) mm. Carry out the test in accordance with 5.5 on two unused test samples with a length of at least 1 500 mm. Carry out the tests in accordance with 5.6 on three unused test samples with a minimum length of 5 m for single and half ropes, and 10 m for twin ropes, cut out of the available test sa

40、 of (50 5) C and less than 20 % relative humidity. Then condition these test samples in an atmosphere of (23 2) C and (50 2) % relative humidity for at least 72 h. Then start testing these samples at a temperature of (23 5) C within 10 min. 5.3 Construction, diameter, and mass per unit length 5.3.1

41、Procedure Clamp the test sample at one end. Load the test sample without shock with a mass1)of: (10 0,1) kg for single ropes, (6 0,1) kg for half ropes, (5 0,1) kg for twin ropes at a distance of at least 1 200 mm from the clamp. After applying the load for 60 s mark within the next 10 s a reference

42、 length of (1 000 1) mm on the test sample. The distance of the marking from the clamp or attachment for the test sample shall be at least 50 mm. Within a further 3 min measure the diameter in two directions around the diameter starting at points 90 apart at each of three levels approximately 100 mm

43、 apart. If the rope cross section is not circular, the maximum and minimum diameter are to be determined in each section. The length of the contact areas of the measuring instrument shall be (50 1) mm. The rope cross-sectional area shall not be subject to any compression during the measurement. Then

44、 cut out the marked portion of the test sample and determine the mass to the nearest 0,1 g. Check that the construction of the rope is a kernmantel construction. 5.3.2 Expression of results Express the diameter as the arithmetic mean of the six measurements to the nearest 0,1 mm. Express the mass pe

45、r unit length in ktex or g/m to the nearest 1 g. 5.4 Sheath slippage 5.4.1 Principle The rope is drawn through the apparatus illustrated in Figure 4, where the movement is restricted by radial forces. The resulting frictional force on the sheath causes slippage of the sheath relative to the core. Th

46、e extent of this slippage is measured. 1) The mass can be introduced by a corresponding force.

Before cutting the other end of each test sample to size, apply a short leng

48、th of adhesive tape around the rope, where it is to be cut, at right angles to the axis of the rope. The adhesive tape shall be at least 12 mm wide before cutting, and the angle of wrap around the rope, , shall be 150 180. After affixing the adhesive tape, cut the sample to a length of (2 250 10) mm with a sharp knife, within the width of the tape, at right angles to the axis of the rope (see Figure 5) such that the adhesive tape remainin
