New Standard from Last Update.

1. Scope

This standard (Part 4) specifies a method for taking cores from hardened concrete, their examination, preparation for testing and determination of compressive strength.

NOTE - Extracting other types of specimens from structures and pavements, like beam specimens and slab removal are given in Annex A.
