Declaration of uncertainties in test reports Ingestion-build-205840 NOTE: Coupling systems between permanent

NOTE: Coupling systems between permanent coupled vehicle units are not in the scope of this standard

According to ISO 8686‐1 there are two general approaches to proof‐of‐competence calculations: the limit state method

time behavior

followed by higher practical concentrations after a period of acclimatization

Declaration of uncertainties in test reports Ingestion-build-205840 NOTE: Coupling systems between permanent1 Scope The purpose of this document is to indicate how to present the uncertainty data determined by EN ISO 129991 in a laboratory test report of the Sound reduction index R of a building product or a building system, determined in accordance with EN ISO 7171 and EN ISO 101402: 2010, Figure B. 1. It is planned to include this information in EN ISO 101402.
