FRICTION PENDULUM

Abstract

The purpose of a Friction Pendulum Test is to determine the sensitivity of explosives when subjected to a glancing blow with its attendant friction. A test consists of ten trials with the steel shoe, except when complete explosion or burning occurs in any trial. If explosion or burning occurs, the trials with the steel shoe are discontinued. Ten trials are made with fiber faced shoe only when complete explosion or burning occurs with steel shoe, or as prescribed in test directive. If the explosive passes the test with the use of the steel shoe, no further trials are conducted. From a viewpoint of economy and efficiency, therefore, all samples are tested first with the steel shoe. Each trial consists of 7 plus or minus 0.1 grams of explosive.
