The European Committee for Standardisation has released a draft of the second part of the Geotechnical monitoringby field instrumentation standard for industry review and comment.
Part two of ISO 18674 cover displacement measurements along a line using an extensometer and BSI is inviting UK-based geotechnical engineers to comment on the draft by 9 September.
The draft publication follows on from the first section covering general rules which was put out for review in August 2013. A further eight sections are in preparation and will cover inclinometers, piezometers, total pressure cells, hydraulic settlement gauges, strain gauges, load cells, geodetic monitoring instruments and vibration monitoring instruments.
The standard provides details of the different types of extensometer and the accuracy, as well as the applications that they are best suited to. The standard also covers installation, monitoring and data interpretation.
To review the standard and comment, please go to www.bsigroup.com before 9 September.
