3 Terms and definitions
For the purposes of this document, the terms and definitions given in prEN 13857-1:2021 apply.
4 Principle
The explosive is initiated using the means of initiation foreseen by the manufacturer, e.g. detonator,
booster or detonating cord. The test is successful when complete detonation of the explosive is
observed.
5 Apparatus
5.1 Means of initiation, as specified by the explosives’ manufacturer.
5.2 Steel tubes: the dimensions of the steel tubes shall be in accordance with Table 1.
The steel quality shall be structural steel with a minimum yield strength of 235 MPa at 16 mm, which is
specified in accordance with EN 10025-2:2005 as “S 235 xx”.
In case of cartridged explosives, the internal diameter of the steel tube shall be the smallest where the
cartridges still can be inserted into it without difficulty.
In case of bulk explosives, the internal diameter of the steel tube shall be the nearest diameter equal or
less to the smallest diameter which the manufacturer specifies for use of the bulk explosive.
prEN 13631-10:2021 (E)
In case the start-stop-method (prEN 13631-14:2021, 5.4.1) is used, holes shall be drilled in the tube to
allow the insertion of the sensors of the measuring equipment at positions in accordance to 6.2. The
diameter of the holes shall be no larger than to allow the insertion of the sensors (prEN 13631-14:2021,
5.4.1).

NOTE The dimensions are in accordance with ISO 4200:1991, Table 1, “range of preferred thickness E”,
which are commercial steel tubes for general use. To facilitate the use in this standard the outer diameter
dimensions given in ISO 4200:1991, Table 1 have been converted to inner diameter values.
5.3 Thermometer, capable of measuring the temperature of the test environment and the
temperature of the high explosive with an accuracy of ± 1 °C.
5.4 Balance, with an accuracy to 1 g.
5.5 Measuring tape, capable of measuring length up to 200 cm with an accuracy of 1 mm.

specified in prEN 13630-7:2021, 5.3.
prEN 13631-10:2021 (E)
6 Test pieces
6.1 Cartridged Explosives
For the test with cartridged explosives, cartridges shall be used of the smallest diameter placed on the
market by the manufacturer.
The test piece shall comprise a cartridge or column of cartridges of length of at least L, expressed as
formula:
L = 5 d + l
where:
L is the length of cartridge or column of cartridges necessary for conducting this test;
l is the length between sensors as specified for the measuring equipment of velocity of
detonation;
d is the cartridge diameter.
NOTE The length 5 d is larger than the propagation length for the explosives in cartridge form.
In view of limiting damage to the environment, noise and impact on work safety it is acceptable to use
test pieces of length L only but in some cases the test piece may be longer than length L.
When the length of an individual cartridge is less than L, prepare each test piece by joining two or more
cartridges together. In case of clipped cartridges or cartridges with rounded ends, the end portions of
two cartridges shall be cut off to form a flat surface, with the cross section not less than the diameter of
the cartridge, and the cartridges shall be joined by butting together and taping securely.
Measure the diameter of the explosives using the calliper (5.6). Measure the length of the test piece with
measuring tape (5.5). Weigh the mass of test piece using the balance (5.4). Record all the values.
6.2 Bulk explosive
The test piece shall be prepared up by filling a steel tube (5.2) with the bulk explosives.
The length of the steel tube shall be at least of length L, expressed as formula:
L = 5 d + l
where:
L is the length of cartridge or column of cartridges necessary for conducting this test;
l is the length between sensors as specified for the mea
