The Explosion Effects Sub-Committee EESC of ESTC recommended in 1980 the investigation of fragments and debris arising from an untraversed bomb stack, one having a standard 2 degree traverse and also one with a 10 degree traverse. In addition, the effect of having such a stack inside a typical brick built storehouse with a protective concrete roof, under comparable traversed conditions, was also to be determined. As a result of reservations expressed by RARDE concerning the symmetry of the bomb stacks used in Phase 1 it was decided to carry out a Phase 1B search over part of the sites used during Phase 1. A Phase 2 had been recommended because of some doubts as to the applicability of the trails to buildings which were considerably weaker than those tested, e.g., with 115mm brick walls and because it was not felt that the results allowed extrapolation down to small quantities of explosives less than 1800 kg. Phase 2 was proposed using smaller quantities of explosives, typically of a few hundred kilograms, in a similar type brick built building to ascertain the effect of reduced loading.
