BS EN ISO 22477-5:2018 PDF Download

BS EN ISO 22477-5:2018 is an international standard that focuses on conducting tension tests on anchors grouted in the ground. It is part of a set of standards that includes BS EN 1997-1:2004+A1:2013 and EN 1537:2013, which define the design and execution requirements for grouted anchors. This standard is aimed at various stakeholders involved in ground anchor design, construction, testing, monitoring, and maintenance, including contractors, consultants, engineers, and manufacturers.

The standard provides specifications for the execution of tension tests on grouted anchors, which are used to provide support to various geotechnical structures subject to horizontal load, uplift, and other forces. It describes three test types and their associated test methods, which involve cyclic tension loading with measurement of displacement or loss at load stages, as well as step-loading with measurement of displacement under successive maintained tension loads. These test methods should be used consistently for all test types.

Additionally, the standard covers specifications for experimental devices, measurement apparatus, test procedures, the definition and presentation of test results, and record-keeping. However, it does not provide specifications for the size of the proof load and the limiting criteria, as these are outlined in the UK National Annex to BS EN 1997-1.
