Specification for measurement microphones - Specifications for laboratory standard microphones1 Scope This part of IEC 61094 specifies mechanical dimensions and certain electroacoustic characteristics for condenser microphones used as laboratory standards for the realization of the unit of sound pressure and for sound pressure measurements of the highest attainable accuracy. The specifications are intended to ensure that primary calibration by the reciprocity method can be readily carried out. This part also establishes a system for

the strengths as well as limitations of this technique and analytical results for halogens and sulphur obtained on waste samples

ISO/IEC TS 19795-9 provides a general framework usable for all modalities as well as dedicated recommendations when needed

you can design fitting ends ensuring high quality and reliability for use in aircraft

and as a consequence absolute sustainability is not currently attainable
