Geotechnical investigation and testing - Field testing - Part 5 : flexible dilatometer test

ISO 22476-5:2012 specifies the equipment requirements, execution of and reporting on flexible dilatometer tests. ISO 22476-5:2012 is applicable to tests in ground stiff enough not to be adversely affected by the drilling operation. ISO 22476-5:2012 is applicable to four procedures for conducting a test with the flexible dilatometer. ISO 22476-5:2012 applies to tests performed up to 1 800 m depth. Testing can be conducted either on land or off-shore.

ZOOM ON ... the Requirements department
To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.

With Requirements, quickly access the main part of the normative text!
