26、in prEN 13857-1:2001 and the following apply. 3.1 free-flowing explosive solid, liquid or pasty material in such a form that it is readily transferred from one container to another by pouring to give one continuous, homogenous mass 4 Apparatus 4.1 Tank, containing a suitable inert liquid such as wat
27、er or paraffin oil in which the cartridge can be immersed. 4.2 Thermometer, capable of measuring the temperature of the liquid to an accuracy of 1 C. 4.3 Weighing machine, capable of weighing to an accuracy of 0,5 g. For cartridged explosives, a hook shall be provided for attaching the cartridge und
28、erneath. 4.4 Graduated measuring cylinder, of capacity 250 ml (or greater) capable of measuring to an accuracy of 1 ml. 5 Procedure 5.1Apparent density 5.1.1Cartridged explosives Measure the temperature of the liquid and calculate its density. Weigh the cartridge in air (mass M1). Attach the cartrid
29、ge to the hook and suspend it underneath the weighing machine so that the cartridge is fully immersed, without touching the bottom or sides of the tank, and reweigh (mass M2). 5.1.2Free-flowing explosives Place an empty measuring cylinder on the weighing machine and record its mass (M3). Introduce a
30、 minimum of 50 g of the explosive substance, tamp lightly (for solid explosives), record the volume of the product in the cylinder (V1), reweigh the cylinder and contents (M4). 5.1.3Non-free-flowing explosives The apparent density of non-free-flowing explosives shall be taken as the true density, de
31、termined in accordance with 5.2.1.
