3 Terms and definitions
For the purposes of this document, the following terms and definitions apply
3.1
rope clamp
mechanical device which, ii attached to a rope ci an accessory cord of appropriate diameter, will clamp under load in one direction and move freely in the opposite direction
3.2
lockIng devIce
device that, when closed around a rope, prevents the unintended removal of the rope from the rope clamp
4 Safety requirements
4.1 Design
4.1.1 Rope clamps shall have a locking device or similar mechanism that, if closed prevents a rope or an accessory cord with a diameter within the range marked on the rope clamp (see Clause 6) from being removed from the rope clamp The rope clamps shall be designed in such a way that when used in accordance with the manufacturer’s instructions, at least two independent actions shall be needed, before the rope or accessory cord can be released from the rope clamp.
4.1.2 When tested according to 5.2.2 rope clamps shall clamp onto a rope or an accessory cord in one direction and to move freely in the opposite direction.
4.1.3 When tested according to 5.3.1 rope clamps shall not completely break the rope or accessory cord,
4.1.4 When tested according to 52,3 rope damps shall have an attachment point of at least diameter 13mm (see Figure 1). The edges of all openings for handles and connectors or sling attachment shal be as shown in Figure 1.
4.1.5 When tested according to 5.2,1 all edges of a rope clamp shall be free of burrs.
5.3 Strength test
5.3.1 Determination of the strength
Attach a rope according to EN 892 or EN 1891 or accessory cord according to EN 564 of maxmum diameter as marked on the rope clamp, to the rope clamp as specified by the manufacturer and a connector in the attachment point of the rope clamp. Fix the system in a tensile testing machine and load ii with a force of (4 i 0,1) kN using a test speed of (100 ± 50) mmimin. Release the load immediately. Repeat four more times.
Move the rope damp between application of each force, so that the locking force is applied to a prevlously unloaded point of the rope or accessory cord in each case.
Repeat the procedure using a rope or accessory cord of minimum diameter, as marked on the rope clamp. Note any visible signs of damage or deformation, which can impair its function,
5.3.2 PushIng test
Attach a loop of rope according to EN 892 or EN 1891 or accessory cord according to EN 564 of maxinum diameter as marked on the rope clamp to the rope clamp as specified by the manufacturer and a connector in the upper hole of the rope clamp (see Fige 2). If there is no upper hole, clamp or use any other means of attachment without influence on the test. Fix the system in a tensile testing machine and load it with a force of (400 t 10) N. using a test speed of (100 ± 50) mm/miri. Release the load immediately. Repeat the procedure using a rope or accessory cord of minimum diameter, as marked on the rope clamp.
Note any visible signs of damage or deformation, which can impair its function.
