DIN EN ISO 12999-1 specifies procedures for assessing the measurement uncertainty of sound insulation in building acoustics. It provides instructions for a detailed uncertainty assessment; a determination of uncertainties by interlaboratory tests; and an application of uncertainties. Furthermore, typical uncertainties are given for quantities determined according to ISO 10140, ISO 16283 and ISO 717. The committee responsible for this standard is NA 062-02-31 AA "Schalldämmung und Schallabsorption, Messung und Bewertung" ("Sound reduction and sound absorption; Measurement and evaluation") at DIN.
