This document specifies the following features:

a)    type of cone penetration test;

b)    cone penetrometer class according to Table 2;

c)    test categories according to Table 3;

d)    penetration length or penetration depth;

e)    elevation of the ground surface or the underwater ground surface at the location of the cone penetration test with reference to a datum;

f)     location of the cone penetration test relative to a reproducible fixed location reference point;
