EN 13630-10:2005 (E) 4 1 Scope This European Standard specifies a method for determining the initiating capability of flexible plastic-coated detonating cords

23、and flexible fibrous-overbraided detonating cords, for civil use. It applies only to those detonating cords, having a maximum grammage of 40 g/m, that are used to initiate another detonating cord or a high explosive. NOTE The limitations of this method are described in Annex B. 2 Normative reference

24、s The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EN 13763-15, Explosives for civil uses - Detona

(ISO/IEC 17025:1999) 3 Terms and definitions For the purposes of this European Standard, the terms and definitions given in EN 13857-1:2003 apply. 4 Principle A detonating cord is taped tightly to a stack of paper cards. The detonating cord is detonated and the total numbers of cards cut is u

27、sed as a measure of the initiating capability of the detonating cord. 5 Apparatus 5.1 Detonator A detonator of equivalent initiating capability, determined in accordance with EN 13763-15, as specified by the manufacturer of the detonating cord. 5.2 Paper cards Cards cut from plain non-coated paper o

28、f a grammage (g c ) between 240 g/m 2and 260 g/m 2as determined according to EN ISO 536. The dimensions of the paper cards shall be (100 5) mm long and (50 5) mm wide. 5.3 Support plate Steel or aluminium plate (200 20) mm long and (60 5) mm wide. The thickness shall be at least 4,0 mm. 5.4 Tape Sti

29、cky tape, width (20 2) mm. EN 13630-10:2005 (E) 5 6 Test pieces Select five pieces of detonating cords, each of (500 50) mm in length. 7 Procedure Select such a number of paper cards that after the test at least five paper cards are completely uncut. NOTE Depending on the grammage of the paper, the

30、number of cards likely to be required is 24 to 33 for 12 g/m detonating cords and 35 to 45 for 24 g/m detonating cords. Place the paper cards on top of the support plate. Tightly connect one end of the detonating cord with three equally spaced pieces of tape to the paper cards and the support plate.

31、 Provide an excess end of (50 10) mm of detonating cord (see Figure 1). Dimensions in millimetres Key 1 paper cards 2 tape 3 support plate 4 detonating cord Figure 1 - Detonating cord connected to the paper cards and support plate At the other end of the detonating cord tape the detonator to the det

32、onating cord over a distance of (25 5) mm or in a manner specified by the manufacturer. Place the assembly on a solid base of steel or concrete. Fire the detonator. Collect the paper cards. Count the number of paper cards that are cut completely. Add the total number of partially cut cards using the

33、 percentage (with an accuracy of 5 %) of each paper card that has been cut (i.e. if the paper card is cut for 30 mm add 0,3 to the number of cut cards). The number of cut paper cards (X) is the sum of the total and partial cut cards. Perform the test five times. EN 13630-10:2005 (E) 6 8 Calculation

34、of results The initiating capability (IC n ) of each detonating cord is calculated using the equation: NOTE although the unit of IC is g/m 2 , IC will be used without units when expressing the results. where: n is the number of the test IC nis the initiating capability of the detonating cord in the

35、n thtest (-) X nis the number of paper cards cut in the n thtest (-) g c is the grammage of the paper cards in g/m 2 Report the result as the arithmetic mean of the five individual values, rounded down to the nearest whole number. 9 Test report The test report shall conform to EN ISO/IEC 17025. The

36、following information shall be given: a) initiating capability claimed by the manufacturer; b) type and grammage of paper card used in the test (g c ); c) individual results of all five tests in the form of the total number of paper cards cut (X n ) and the calculated initiating capability (IC n );

38、 (informative) Restriction of the test method This test was developed in CEN/TC321/WG3 by several manufacturers and notified bodies. After extensive research it was concluded that the reproducibility of the test was good, but the repeatability was not. It should be noted that difficulty may be exper

39、ienced in obtaining consistent results between different laboratories, as a consequence of variations in age or quality of the paper used. To compare IC values of detonating cords obtained using two different types of paper one will need a correction factor. Furthermore IC values obtained for mild d

40、etonating cords manufactured with low explosive concentrations (in terms of grammage per meter) have not been evaluated thoroughly and should therefore be reviewed critically.
