CEN/TC 341/WG 2 - Cone and piezocone penetration tests

This document establishes equipment, procedural and reporting requirements and recommendations on cone and piezocone penetration tests.
NOTE       This document fulfils the requirements for cone and piezocone penetration tests as part of geotechnical investigation and testing according to the EN 1997 series.
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;
g)    pore pressure dissipation tests.
This document covers onshore and nearshore cone penetration test (CPT). For requirements for offshore CPT, see ISO 19901-8.

This standard covers the field vane test used in cohesive soils for the determination of the undrained peak and remoulded shear strength and the sensitivity of the soil. The Field Vane Test is used to determine undrained shear strength of cohesive soils, by pushing a rectangular vane body into cohesive soil and rotating it. During rotation the torque and rotation are measured. From the measured torque and the dimensions of the vane the undrained shear strength can be derived. With this test the remoulded strength can also be measured.

2012-02-15 EMA: WI deleted following the 3-year timeframe rules.
2011-05-09 EMA: WI reactivated due to reception of resolution requesting 9 months tolerance before FV (res 164 taken on 2011-04-15).
2011-05-06 EMA: WI deleted following the year timeframe rules.
2009-02-12 SJ: resolution 99/2008 was missing the inforamtion related to the CEN members willing to participate. Since the corresponding items have been approved in ISO, the issue was brought to light. We have now received the missing infromation.

2006-10-13  Deleted due to 3YTF (formal vote).
Tolerance of nine months applied before enquiry by resolution CEN/TC 341 41/2004 (note by JLM 2004 08 23).
