ČSN EN ISO 12999-1

This document specifies procedures for assessing the measurement uncertainty of sound insulation in building acoustics. It provides for
- a detailed uncertainty assessment;
- a determination of uncertainties by inter-laboratory tests;
- 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).
