IS 4968 : Part 1 : 1976 Method for subsurface sounding for soils: Part 1 Dynamic method using 50 mm cone without betonite slurry

1. SCOPE

1.1 This standard covers the procedure for determining the resistance of different soil strata to dynamic penetration ofa So-mm cone and thereby obtaining an indication regarding their relative strengths or density or both. The method helps reconaissance survey of wide areas in a shorter time which will enable selective in situ testing or sampling for typical profile. It can provide useful data for local conditions where rebable correlations have been established.
