29、he shock-wave from one unit to another and/or to delay the signal. This can be done by means of surface connectors, relays and coupling accessories.

37、) C, ensuring that the ends of the receptors are kept out of the water. Unless otherwise specified by the manufacturer, ensure that the free end of the surface connector or relay remains submerged during conditioning. After conditioning, remove the connector or relay from the water. Place witness pa
38、pers at the end of each receptor. Initiate the donor using the initiating device and check the witness paper at the end of each receptor. Record whether or not the shock-wave has been successfully transferred to all of the receptors. 6.2 Surface connectors or relays designed to be hung from near-ver
39、tical rock faces If the surface connector or relay is of a type designed only to be hung from a near-vertical rock face and not laid on the ground, where it may be exposed to puddles of water, as stated by the manufacturer, the procedure described in 6.1 shall be performed with the connector or rela
40、y subjected to the ingress of water test for IPX4 (spray test) as described in EN 60529, instead of total immersion in water. 6.3 Coupling accessories other than those designed to be hung from near-vertical rock faces Connect the maximum number of receptors claimed by the manufacturer to the couplin
41、g accessory in accordance with the manufacturers instructions. Condition the full assembly by submerging it in water at a depth of (0,5 0,1) m for 1 0 48+ h at a temperature of (20 5) C, ensuring that the ends of the receptors are kept out of the water. After conditioning, remove the coupling access
42、ory from the water. Place witness papers at the end of each receptor. Initiate the donor using the initiating device and check the witness paper at the end of each receptor. Record whether or not the shock-wave has been successfully transferred to all of the receptors. 6.4 Coupling accessories desig
43、ned to be hung from near-vertical rock faces If the coupling accessory is of a type designed only to be hung from a near-vertical rock face and not laid on the ground, where it may be exposed to puddles of water, as stated by the manufacturer, the procedure described in 6.3, shall be performed with
44、the coupling accessory subjected to the ingress of water test for IPX4 (spray test) as described in EN 60529, instead of total immersion in water. These subclauses 6.3 and 6.4 shall include all transfers, which are specified in the information to be provided by the manufacturer or his authorised rep
45、resentative to the user according to EN 13857-3. 7 Test report The test report shall conform to EN ISO/IEC 17025.
