DIN EN 13791/A20
Assessment of in-situ compressive strength in structures and precast concrete components; Amendment A20
Bewertung der Druckfestigkeit von Beton in Bauwerken oder in Bauwerksteilen; Änderung A20
Overview
This Amendment to DIN EN 13791 contains the amended National Annex to the German version of EN 13791:2007. The Amendment is intended to replace the national annex of DIN EN 13791. Although the National Annex has only been partially amended and supplemented, the Working Committee NA 005-07-05 AA "Prüfverfahren für Beton" ("Test methods for concrete") has decided to replace the National Annex completely in order to simplify manageability and readability. EN 13791:2007, which is not included in this document, has been prepared by Technical Committee CEN/TC 104 (secretariat: DIN, Germany). This National Annex contains those rules for the assessment of the compressive strength of concrete in structures or in parts of structures which, according to EN 13791, are to be regulated in national rules, or additional rules for applications which are explicitly not regulated in the European Standard (see Clause 1 of EN 13791).
