适用范围：This British Standard complements BS EN 13791, which gives methodsfor determining the characteristic in-situ compressive strength inconcrete structures and precast concrete components based on:a) core testing;b) rebound hammer, ultrasonic pulse velocity and pull-out forcemeasurements after a relationship with core strength has beendetermined 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 testspecimens is in doubt (see Clause 7).In addition, this British Standard provides guidance on the followingcases not covered by BS EN 13791:? assessment of an unknown structure using a margin based on thet-statistic (see 6.2);? use of indirect methods without correlation to core strength(see 6.3);? relative testing, i.e. comparison of a volume of concrete underinvestigation with concrete in similar elements that has beenaccepted (see 6.4);? action when the producer has declared nonconformity (seeClause 8).This British Standard does not provide guidance on:? the use of cores with a diameter of less than 50 mm or the use ofmicrocores;? whether a structure has adequate durability;? the use of in-situ testing as an alternative to conformity testingbased on test specimens.
