Bruceton test

T.W. Anderson et al, NAVORD Rept 65-46 (1946) described seven varieties of staircase method including the Bruceton test. Natrella (Ref 42a) also gives several References to other discussions of the up-and-down or staircase method of testing... [Pg.1080]

The Bruceton test affords a fairly good estimate of the 10, 50 and 90% firing points for minimum trials, but depends heavily on the assumption that the sample sensitivity follows a normal distribution about the median firing height... [Pg.1080]

The Bruceton test (as expected) gives a good value of the mean drop height, ie 50%... [Pg.300]

N. E. Hanna et al, US Bur Mines RJ No 5463 (1959) CA 53, 14517 (1959). The effect of 0, 3.6, 6.6 9.5% NaCl on the incendivity of permissible explosives was studied by the Bruceton up-and-down technique in gallery tests. The study showed that the addn of relatively small quantities of NaCl tends to reduce but does not eliminate ig-... [Pg.286]

The Bruceton method is also frequently used in other destructive tests, eg in functioning tests of detonators, gap tests for shock sensitivity, or in tests where the test alters a sample so that it is no longer in its original state... [Pg.301]

A 40mg sample is placed on a brass cap which is inverted over the anvil. The falling weight is normally 5kg. If the volume of gas evolved by a 0.03mg sample is more than 1ml, then the test is considered a go. The Bruceton method is used and results are reported as Figure of Insensitiveness or FI which is ob-... [Pg.302]

During World War II Dixon and Mood [72] developed a special experimental method for testing the sensitiveness of explosives to impact. The method gave a statistical estimation of the mean value. It became known as the Bruceton up-and-down method. The primary advantage of the method is that it increases the accuracy with which the mean value can be economically determined. The method requires fewer tests than other methods. [Pg.445]

When the Bur of Mines Explosives Experiment Station was established at Bruceton, Pa, the tests for permissible expls started to be conducted there. Right from the beginning many expls were submitted for testing but only a few passed the tests. This was because most of the submitted mixts were compounded without any consideration to oxygen balance, heat of expln (or deflagration) or max temp developed on expln. In... [Pg.229]
