365 Water Stemming cut off at one end, and the cartridge is tested for detonation and transmission with the aid of a No. 6 blasting cap. The criterion for the water resistance of the explosive is the time of exposure to water, after which it still retains its capacity to detonate the cartridge in three trials, without leaving any non-detonated residual explosive behind. There is no generally accepted quality classification. Nevertheless, water resistance of an explosive is considered to be satisfactory, acceptable, or poor if the cartridge can still be detonated after 24, 8, or 2 hours respectively. In Germany, the following method for testing the water resistance of powder-form permissibles has been laid down at the Test Station at Dortmund-Derne. A train of four cartridges is fixed in a file on a wooden board; the first of the four cartridges is equipped with a detonator No. 8. Five longitudinal, 2 cm long notches, uniformly distributed over the circumference, are cut into each cartridge. The train is immersed for 5 hours in water, in a horizontal position, 20 cm under the water surface, after which they are detonated. The train must detonate in its entirety. This method, including some additions regarding the preparation of the test sample is standardized as EN 13631-5 as a so-called Harmonized European Standard. The water resistance of partly water – soluble, powder-form explosives (e.g. ammonium nitrate explosives or blasting agents) can be improved by the addition of hydrophobic or gelling agents. If e.g. W Guar Gum is added, the water entering immediately forms a gel which blocks the penetration of more water. Water-resistant Detonator Unterwasserzünder; détonateur pour tir sous l’eau Such detonators differ from conventional detonators in being watertight; water cannot penetrate into the detonator even under increased water pressure (W Bridgewire Detonator). Water Stemming Wasserbesatz; bourrage à l’eau Water stemming of explosive-blasted boreholes consists of waterfilled cartridges made of plastic material, which give some protection against firedamp and coal dust explosions.
Web Web In a solid propellant grain, the minimum distance which can burn through as measured perpendicular to the burning surface (W Burning Rate). Weight Strength The strength of an explosive material per unit of weight expressed as a percentage of the weight of a recognized explosive standard. W Strength.
