ISO 6926:2016 specifies the acoustical performance requirements for reference sound sources: - temporal steadiness (stability) of the sound power output; - spectral characteristics; - directivity. Temporal steadiness is defined in terms of the standard deviation of repeatability (see 5.2). The spectral characteristics can be verified in either a hemi-anechoic room or a reverberation test room from measurements of the frequency band sound power levels in accordance with this International Standar...view more

ISO 18580:2015 specifies the verification method of total running resistance force when the exhaust gas emissions and/or fuel consumption of motorcycles are measured during mode running on a chassis dynamometer. The performance of chassis dynamometer is verified by comparing the measured total running resistance force (measured by a chassis dynamometer absorption force) and the target total running resistance force (calculated from velocity, acceleration and/or deceleration). This International ...view more
