Acoustics. Attenuation of sound during propagation outdoors - Calculation of the absorption of sound by the atmosphere Ingestion-build-65808 proper measurements require adequate planning

proper measurements require adequate planning and understanding of the measurement systems and their results

and this standard applies only to that type although many of its principles could be used for others

The objective of this standard is to define limits and test methods for apparatus in relation to electromagnetic emissions which may cause interference in other apparatus

having average run lengths (ARLs) at the target level of at least 1 000 and 200 respectively
