scope:

This standard applies to the planning, execution, evaluation and documentation of deformation measurements. Surveys are carried out to monitor the condition of technical objects (buildings, machinery and plant, etc.) and natural objects (embankments, slopes liable to landslides, etc.), to determine their movements and distortions and to document the state of the respective object(s).

Deformation measurements shall be carried out with the objective of providing short-term or medium-term protection against hazards caused by or related to the objects being monitored. Early detection of movements and distortions is also useful for the maintenance and inventory assurance of objects.

Interpretation of the results other than for the purpose of evaluating deformation measurements is not the subject of this standard.

This standard is intended to standardize and ensure the quality of the proofs obtained by deformation measurements, and it is essential that the results of the deformation measurements can be interpreted unambiguously.
