28、 the terms and definitions given in prEN 13857-1:2001 apply. 4 Immersion test for detonating cords 4.1 Principle A test piece is immersed in water under tensile load for a given time and its ability to be initiated is then checked using a detonator and a witness plate. 4.2 Apparatus 4.2.1Tank of wat
29、er, open at the top, of a sufficient size. The temperature of water shall be (20 10) C. 4.2.2Means of supporting the test piece. A suitable means is shown in Figure 1; in this case, the diameter of the pulleys shall be sufficiently large that they do not cause damage to the cover of the test piece a
30、nd shall be at least 100 mm. One pulley shall be attached to the bottom of the tank. 4.2.3Weight, or other means, to subject the test piece to a tensile load of 5 0 400+ N, unless the detonating cord has been designed for use in a specific application. In the latter case, the weight, or other means,
31、 shall be that specified by the manufacturer.

35、 measuring the burning duration. 5.2 Apparatus 5.2.1Tank, open at the top, of a sufficient size. 5.2.2Weight, of mass (500 50) g. 5.2.3Apparatus for the measurement of burning duration, as described in EN 13630-12. 5.3 Test pieces Select five lengths of safety fuse, each (1 500 50) mm long. 5.4 Proc
36、edure Fill the tank with water to a height of 25 0 500+mm. Immerse the test piece in the water and position the weight (5.2.2.), so that the midpoint of the test piece is kept in contact with the bottom of the tank, as shown in Figure 2. Keep the test piece in the water for 24 h. Remove the test pie
37、ce from the tank and cut off a (1 000 5) mm length from the section which was immersed. Measure the burning duration of the immersed length using the unconfined test described in EN 13630-12.
