注:1 the figures in the table are applicative in the quality assurance period starting from the accomplishment of production. 2 it is not necessary to measure the gap distance, brisance and capacity of explosive insensitive to detonator. 3 all the figures above are concluded by measurements ofф32mm orф35mm sticks. |
