Conformance testing
This chapter contains the information needed to conduct conformance testing according to the specified
standards.
Mounting for acoustical tests The microphone must be mounted on the preamplifier.
Electrical substitute for the microphone To obtain a BNC Class electrical input, the microphone
must be replaced by an electrical microphone impedance
ST 02 with the serial capacitance 18 pF ± 10%.
