This document specifies procedures for assessing the measurement uncertainty of sound insulation in building acoustics. It provides for

  1. a detailed uncertainty assessment;

  2. a determination of uncertainties by inter-laboratory tests;

  3. an application of uncertainties.

Furthermore, typical uncertainties are given for quantities determined according to ISO 10140 (all parts), ISO 16283 (all parts) and ISO 717 (all parts).
