The 95 % confidence level corresponds to the mean value minus (and/or plus) a tolerance value (see Annex ZA, Table ZA.1 column Notes). Both the mean value and the tolerance value are defined by the manufacturer to be representative of the performance of the product for the corresponding characteristic (these two values are not necessarily based on a statistical calculation). Relevance of codes: A: relevant to all conditions of use S: relevant to specific conditions of use “—”: indicates that the characteristic is not relevant for that product Particular site-specific application cases may contain requirements for additional properties and - preferably standardized - test methods, if they are technically relevant and not conflicting with European Standards. The design life of the product should be determined, since its function may be temporary, as construction expediency, or permanent, for the lifetime of the structure. SIST EN 13492:2018
