This European Standard:
-- gives methods and procedures for the assessment of the in-situ compressive strength of concrete in
structures and precast concrete components;
-- provides principles and guidance for establishing the relationships between test results from indirect test
methods and the in-situ core strength;
-- provides guidance for the assessment of the in-situ concrete compressive strength in structures or
precast concrete components by indirect or combined methods.
This European Standard does not include the following cases:
-- where indirect methods are used without correlation to core strength;
-- assessment based on cores less than 50 mm in diameter;
-- assessment based on less than 3 cores;
-- use of microcores.
NOTE In these cases provisions valid in place of use apply.

regarding national provisions dealing with the fourth and sixth items in the
above list,
This European Standard is not for the assessment of conformity of concrete compressive strength in
accordance with EN 206-1 or EN 13369 except as indicated in EN 206-1:2000.5.5.1.2 or 8.4.
