This British Standard is the UK implementation of EN ISO 22476-5:2012. It partially supersedes BS 5930:1999+A2:2010, which is currently being revised in order to remove conflicting material.
ISO 22476 consists of the following parts, under the general title Geotechnical investigation and testing — Field testing:
- Part 1: Electrical cone and piezocone penetration test
- Part 2: Dynamic probing
- Part 3: Standard penetration test
- Part 4: Ménard pressuremeter test
- Part 5: Flexible dilatometer test
- Part 7: Borehole jack test
- Part 9: Field vane test
- Part 10: Weight sounding test [Technical Specification]
- Part 11: Flat dilatometer test [Technical Specification]
- Part 12: Mechanical cone penetration test (CPTM)
