Of these tests the Trauzl Test , also known as Lead Block Expansion Test is one of the oldest and it became, since 1903, an official test in most of the countries of the world (except GtBritain USA). Accdg to Pe rez Ara (Ref 8, p 113) this test was invented by Beckerhinn in 1877, but accdg to Stettbacher (Ref 6, p 362) an Austrian scientist Trauzl described the method in 1883. In France the test has been used in a modified form known as coefficient d utilisation pratique (CUP) and is described in Ref 23, pp IX-X XXV-XXVI and in Ref 26 

Ballistic Pendulum Test, described briefly in Ref 23, pp VII-VIII, has been used in USA and until 1949 in GtBritain (Ref 13, p 185). Ballistic Mortar Test, described briefly in Ref 23, p VII is used now in GtBritain (Ref 13, pp 185-86) 

Besides the above listed tests there are the Cratering Test (Ref 23, p X), Quinan Test (Ref 23, p XXI Ref 26). Guttmann Test (Ref 8, p 118) and Mortar Test (Ref 23, p XIX Ref 6a, p 66). They are not official tests 

Cook (Ref 17, p 271-L) defines power as the rate of doing work , but it may also be defined as energy divided by time , since power multiplied by time is energy . A watt is a unit of power and watt-hour is a unit of energy
