35、ontrolled Copy, (c) BSI EN 13763-12:2003 (E) 6 6 Test pieces 6.1 Detonators intended for use down shot holes Select 50 detonators of a specific type, with the same design and construction. The testing shall be performed with the shortest standard length of shock tube or leading wire specified by the
36、 manufacturer. If the detonators form part of a series with different delay times, use 50 detonators with at least five different delay times distributed as evenly as possible and including the longest delay time in the series. 6.2 Detonators intended for use on the surface only and relays Select 50
37、 detonators or relays of a specific type, with the same design and construction. The testing shall be performed with the shortest standard length of shock tube or leading wire specified by the manufacturer. If the detonators or relays form part of a series with different delay times, use 50 detonato
38、rs or relays with at least five different delay times distributed as evenly as possible and including the longest delay time in the series. 7 Procedure 7.1 Detonators intended for use down shot holes Immerse the detonators in water at a temperature of (T ? 2) ?C, close the vessel and apply a pressur
39、e of (0,30 ? 0,01) MPa where: ? T = 20 ?C if the manufacturer does not claim the product can be used at temperatures exceeding 40 ?C. Keep the detonators in the pressure vessel for 48 h. ? T= highest temperature specified by the manufacturer if the product is to be used at temperatures exceeding 40
40、?C. The cooling rate of the water shall be such that the water temperature reaches 30 ?C within 5 h but not before 3 h. The total test time for the detonators is 48 h calculated from when the specified pressure has been reached. Place the shock tube, if present, in such a way that the open end of th
41、e shock tube is never exposed to pressurised air, either by leading the shock tube end from the water inside the tank to the outside of the tank through a pressure-safe sealing or by totally immersing the detonator assembly in water using properly sealed shock tube ends according to the manufacturer
42、s specification. Unless otherwise specified by the manufacturer, ensure that the free ends of the leading wires remain below the surface of the water during pressure testing phase. After pressure testing, fire the detonators and measure the delay times of the detonators in accordance with prEN 13763
43、-16. The detonators shall be fired within 2 h. 7.2 Detonators intended for use on the surface only and relays Immerse the detonators or relays in the water tank for 48 h in water at a depth of (0,50 ? 0,01) m and at a temperature equal to the highest temperature specified by the manufacturer ? 2 ?C.
44、 Unless otherwise specified by the manufacturer, ensure that the free ends of the leading wires or shock tubes remain below the surface of the water during pressure testing phase. After pressure testing, fire the detonators and measure the delay times of the detonators in accordance with prEN 13763-
45、16. The detonators shall be fired within 2 h.
