DETONATOR OF OPTIMUM AUDIBILITY AND SAFETY. ADDITIONAL TESTS. TECHNICAL SPECIFICATION
Following the tests carried out by the B 63 Committee at Rosenheim in January 1962 (described in Section 3 of Interim Report No. 1), the SNCF and the DB raised with their respective detonator manufacturers the question of the development of a detonator of power equal to that of the new detonator of the DB but which would not produce a fragmentation effect endangering the staff even when located at a short distance from the actual point of explosion. The new tests carried out by the B 63 Committee at Villeneuve in February 1963 dealt with the prototypes developed by the manufacturers consulted. The results of these tests were satisfactory as both the detonator with plastic material casing submitted by the DB and the detonator with brass casing submitted by the SNCF produced an excess pressure of the same order of magnitude as that of the new DB detonator which, during the tests at Rosenheim, had been considered as being satisfactory from the point of view of explosive power. Moreover, the fragmentation produced by these two detonators was not strong enough to penetrate through a light cardboard screen arranged at 3 m from the actual point of explosion. The first task entrusted to the B 63 Committee can thus be considered as having been fulfilled and the results of the various tests can be directly used for the purpose of drafting-out the principal sections of a technical specification for the supply of new detonators.
