If the expl submitted to the BurMines is intended to be used in gaseous and/or dusty coal mines, it shall be tested (in addition to stability) for permissibility in galleries which are located at Bruceton, Pennsylvania. A brief description of these galleries and tests is.given in Vol 3 of Encycl (Ref 13, pp C375 to C377), whereas a detailed description is found in BurMinesBull 346 (Ref 5, pp49-59)... [Pg.513]

Dope-Size Test. It has been recognized that the granulation of the solid ingredients or an expi has an appreciable effect on its expl characteristics a considerable variation might have as much effect as a change in chem compn, and so may cause failure in gallery tests for permissible expls. The "dope-size test" consists of treating a sample of expl (under a hood) with carbon bi-... [Pg.514]

The operation of the scanning electron microscope was in the hands of Walter R. Brown of the National Museum of Natural History. R. M. Organ and Harold Westley of the Smithsonian Institution supplied the spectrographic results for the ink ignition tests. H. P. Stern and T. Lawton (Director and Assistant Director of the Freer Gallery of Art) are thanked for advice on the selection of paintings, for permission to sample them, and for general discussions on the history of Chinese ink. [Pg.231]

The expl is considered to pass the test for permissibility if 5(orl0) consecutive firings of prescribed weight cause no ignition (which is usually followed by expln) of chamber atmosphere. In Austrian gallery the charge is not fired from the cannon, but as indicated below... [Pg.153]

The following permissibility gallery tests are required for newly submitted expls, by Bur Mines regulations listed in Schedule I-H (Ref 45) ... [Pg.158]

The gallery tests listed below are required for field samples. These are of a regularly manufd and previously approved brand of permissible expls removed by the Bureau s representative from a mining company magazine or directly from the field. These samples are collected at any period after acceptance as permissible explosives in order to determine whether they continue to conform to the basic specifications of BurMines (Ref 47)... [Pg.159]

Maximum charge (charge limite) of this or other expls is usually detd experimentally either in a gallery or an experimental coal mine, as described under COAL MINING EXPLOSIVES, TESTING FOR PERMISSIBILITY. These tests verify also the theoretical finding of permissibility of the expl to test... [Pg.231]
