Where stitching is used to provide safety and strength (e.g. in joints) it shall be possible to inspect it and the stitching shall contrast with the textile element in colour or surface appearance.The MCD shall be designed to ensure that the loading is in pre-determined direction(s). Only for category E, the connection between the lanyard and the MCD shall not be able to be placed into the opening of the MCD without a tool. The functioning of the MCD system shall be in accordance with the information supplied by the manufacturer (see Clause 7) and the category or categories as described in 3.6 to 3.10.
4.2 Manual extraction test for categories C, D and E Only for MCD which are used on cable safety lines when tested in accordance with 5.2, the MCD shall not be able to be removed from the cable.
4.3 Static strength 4.3.1 Function under a test load (only for MCD with pulleys) For MCD with pulleys, when tested in accordance with 5.3.2, the pulley wheel(s) of the MCD shall be able to rotate 10 times in both directions (see Figure 6). If the MCD is one-directional, then the requirement is only for the intended direction. 4.3.2 Deformation test for MCD This test applies to MCD of category E and to other categories, where relevant. When tested in accordance with 5.3.3 when the load is released, the permanent deformation of the MCD opening shall be less than 0,5 mm. 4.3.3 Static strength test for all ISS with all categories of MCD When tested in accordance with 5.3.4, the load shall not be released. 4.3.4 MCD transversal static strength test This test applies to MCD of category E and to other categories, if relevant. When tested in accordance with 5.3.5, the MCD shall not release the load.
4.4 Locking devices of the opening of the MCD When the opening of the MCD is closed by a locking device, the side gate test of EN 12275:2013 shall be carried out and its respective requirement met (see EN 12275:2013, 4.2.3.2). If the MCD is closed by a locking device which is not at the place of the opening, both the face gate test and the side gate test of EN 12275:2013 shall be carried out on the locking device and their requirements shall be met (see EN 12275:2013, 4.2.3.1 and 4.2.3.2).
4.5 Stability of tape If the lanyard is made of woven tape not conforming to EN 565:2017, 4.1, when tested in accordance with 5.1, the weft yarn of the tape shall not be released from the tape sample.
4.6 Corrosion resistance When tested in accordance with 5.6, there shall be no corrosion of the metal parts material that would affect their functional operation, e.g. the correct operation of moving elements. The presence of tarnishing and white scaling is acceptable.
5 Test methods
5.1 Design and construction
Check by visual examination and/or measuring, that the requirements of 4.1 are met.
For category E MCD, pre-assembled with a lanyard, check by measurement that the minimum thickness of the lanyard, excluding the attachment loop, is at least 2 mm greater than the opening of the MCD.
5.2 Manual extraction test for categories C, D and E
Introduce by hand the extremity of one side of the MCD opening between two strands of the cablerecommended in the information supplied by the manufacturer (see Clause 7). By manually rotating the MCD along the lay of strands, check that the MCD cannot be removed from the cable (see Figure 4).BS EN 17109 pdf download.
