BS EN ISO 22477-5:2018

This standard BS EN ISO 22477-5:2018 Geotechnical investigation and testing. Testing of geotechnical structures is classified in these ICS categories:

• 93.020 Earthworks. Excavations. Foundation construction. Underground works

This document establishes specifications for the execution of tension tests to be carried out on an anchor grouted in the ground, as defined in EN 1997‑1 and EN 1537. Three methods of testing are recognized by this document. Test Method 1 involves cyclic tension loading with measurement of displacement at the load stages; Test Method 2 involves cyclic tension loading with measurement of load loss at the load stages; and Test Method 3 involves step-loading with measurement of displacement under successive maintained tension loads.

This document provides specifications for the experimental devices, the measurement apparatus, the test procedures, the definition and presentation of the test results and the content of records.

NOTE This document does not provide specification for the size of the proof load and the limiting criteria. These aspects reside in EN 1997‑1 or its national annex for CEN countries and in similar national application documents for this test standard for ISO countries.
