Tasks
An important metrological task is to ensure the
traceability of ballistic measurements within the cope of the Proof
Testing Act (Beschussgesetz – BeschG) to the national
standards by means of special calibration an test devices. These new
measurement devices have been specially developed for security-relevant
dynamic measurands occurring above all upon firing. For user safety,
the gas pressure up to 600 MPa at a very low rising time (of up to
around 20 µs) and short pulse duration (of up to about 3 ms)
as well as the bullet velocity (up to 1200 m/s) are tested as
substantial measurands.
Due to their dangerousness, and in order to avoid their
possible misuse, certain types of firearms as well as powder-actuated
technical equipment (predominantly shooting tools as, for example,
bolt-firing tools, tools for line throwing, deactivating, and cutting
of cables) must be subjected to approval tests before they are released
for manufacture an trade. This is an important task which has been
assigned to PTB by the State under the Proof Testing Act. In particular
it must be checked whether the equipment fulfils the technical
requirements prescribed by the legislator.
