This European Standard: - gives methods and procedures for the estimation of the in-situ compressive strength and characteristic in-situ compressive strength of concrete in structures and precast concrete components using direct methods (core testing) and indirect methods, e.g. ultra-sonic pulse velocity, rebound number; - provides principles and guidance for establishing the relationships between test results from indirect test methods and the in-situ compressive strength; - provides procedures and guidance on in-situ assessment of the compressive strength class of concrete where there is doubt over the strength of concrete recently supplied to a structure or precast concrete component. This European Standard does not include the following cases: - assessment based on cores less than 50 mm in diameter, micro-cores; - assessment of the quality of concrete for properties other than compressive strength, e.g. durability-related properties; - specific provisions for lightweight concretes; - use of pull-out testing; - in the Clause 8 procedures, provisions for less than 8 cores without indirect testing; - use of comparative testing (see FprCEN/TR 17086, Further guidance on the application of EN 13791 and background to the provisions [1] for explanation). (2) This European Standard is not for the assessment of conformity of concrete compressive strength in accordance with EN 206 or EN 13369 except as indicated in EN 206:2013+A1:2016, 5.5.1.2 or 8.4. (3) This European Standard does not cover the procedures or criteria for the routine conformity control of precast concrete components using either direct or indirect measurements of the in-situ strength.
