3.3 Test execution
This chapter describes the user of the digital test hammer to carry out tests.
3.3.1 Criteria to select the impact point
If possible, test vertical surfaces. One should avoid joints, honeycombs and porous areas.
One should take great care with walls that are less than 10 cm thick and columns that are
less than 12 cm thick since they could give misleading concrete hammer readings on
account of their resilience.
3.3.2 Surface preparation
Any plaster or coating covering the concrete should be removed as a first step.
Slightly uneven surfaces caused by wooden forms can be removed with the carborundum
stone that is supplied with the instrument (Ref. 7 del in chapter 2.1).
