1 Scope This British Standard complements BS EN 13791, which gives methods for determining the characteristic in-situ compressive strength in concrete structures and precast concrete components based on:
a) core testing;
b) rebound hammer, ultrasonic pulse velocity and pull-out force measurements after a relationship with core strength has been determined for the particular concrete under investigation.
This British Standard provides additional guidance on:
• planning an investigation (see Clause 5 );
• selection of test methods (see 5.4 );
• selection of the test locations (see 5.5 and 5.6 );
• assessment of individual core results within a group (see 6.1 );
• assessment where the strength of concrete based on test specimens is in doubt (see Clause 7 ).
In addition, this British Standard provides guidance on the following cases not covered by BS EN 13791:
