適用范圍：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 testmethods 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.This European Standard is not for the assessment of conformity of concrete compressive strength inaccordance with EN 206-1 or EN 13369 except as indicated in EN 206-1:2000, 5.5.1.2 or 8.4.
