Page 7: Proper Use
Proper Use The Light Weight Deflectometer LWD WEBERconnect was developed in accordince to the German test regulation TP BF-StB Part B 8.3 as well as the American standard ASTM E2835-11, to test the soil bearing capacity and the achieved degree of soil compaction in the area of soil construction, traffic route engineering or railway construction by means of a dynamic plate pressure test. -
Page 8: Warnings
Warnings In this manual, all warnings are particularly highlighted compared to the remaining text. The warnings are marked in colours and introduced by a signal word that indicates the degree of danger. An icon specifies the kind of danger. All warnings have to be followed strictly to carry out an accident-free work and to avoid injuries and damages. -
