33、d definitions For the purposes of this European Standard, the terms and definitions given in prEN 13857-1 and the following apply: 3.1 drop height distance between the lowest part of the striking head of the drop weight and the uppermost part of the percussion cylinder 3.2 ignition system electrical
34、 resistance heating wire surrounded by an incendiary material 4Apparatus 4.1 Electric, non-electric and plain detonators 4.1.1General The apparatus is a drop hammer (e.g. the BAM fall-hammer), comprising a cast steel block with base, a main anvil and an intermediate anvil, a locating plate, a guide
35、piece, a percussion cylinder, a column, guides and a drop weight with a release mechanism and a striking head. Licensed Copy: sheffieldun sheffieldun, na, Mon Oct 30 02:17:39 GMT+00:00 2006, Uncontrolled Copy, (c) BSI EN 13763-3:2002 (E) 6 4.1.2Drop hammer A steel anvil is screwed onto the steel blo
36、ck and cast base. The steel used for the intermediate anvil and the main anvil is of the same type as for the striking head of the drop weight (see 4.1.3.). The percussion cylinder is a roller bearing with polished surfaces and rounded edges, and is made of steel of type B1 100Cr6 as defined by ISO
37、683- 17:1999. The support onto which the column is fixed (made from a seamless drawn steel tube) is bolted to the back of the steel block. NOTEFigure B.1 shows the arrangement of the BAM fall-hammer (the anvil, the steel block and the column) Figure B.2 shows the arrangement of the lower part of the
38、 BAM fall-hammer. Figure B.3 shows the dimensions of the guide piece and the percussion cylinder. The two guides which are fixed to the column by means of three cross pieces are fitted with a toothed rack, to limit the rebound of the drop weight, and a moveable graduated scale for adjusting the drop
39、 height. The guides shall be vertical. The drop weight release mechanism is adjustable between the guides and is clamped to them by the operation of a lever mechanism. The apparatus shall be firmly secured to a concrete block, with minimum dimensions of (0,6 0,6 0,6) m, by means of four anchoring bo
40、lts. 4.1.3Drop weight The drop weight has a mass of (2000 ? 2) g and is provided with two locating grooves to hold it between the guides as it drops. A suspension spigot, a removable cylindrical striking head and a rebound catch are screwed onto the drop weight. NOTEFigure B.4 shows the design of th
41、e drop weight of the BAM fall-hammer. The removable striking head is made from hardened steel conforming to type 90 MnCrV8 in EN ISO 4957:1999 with polished surface and a diameter of 25 mm. The release mechanism shall be controlled remotely. 4.2 Detonating cord relays, surface connectors and shock t
42、ube Impact testing apparatus, consisting of a (5,0 ? 0,01) kg steel hammer which can be dropped freely from a set height, inside a guide tube onto a steel plate and anvil containing the device to be tested. The anvil shall rest on a concrete floor. NOTEFigure B.5 shows the arrangement of the impact
43、testing apparatus. The hammer is made of steel of type B1 100Cr6 as defined by ISO 683-17:1999. The plates are made of steel of type FE 490-2 as defined by ISO 1052:1982. The anvil is made of steel of type 46 S 20 as defined by ISO 683- 9:1988. 5Test pieces 5.1 Electric detonators Select 50 detonato
