BS EN ISO 22477-5:2018

Geotechnical investigation and testing. Testing of geotechnical structures. Testing of grouted anchors

Status : Current   Published : September 2018



What is this standard about?

This new international standard details how to conduct tension tests on anchors grouted in the ground. Its publication completes a trio of standards on this important structural element. The other two are:

  • BS EN 1997-1:2004+A1:2013, Eurocode 7: Geotechnical design – Part 1: General rules which defines the design requirements for grouted anchors
  • EN 1537:2013 Execution of special geotechnical works – Ground anchors which defines the execution of grouted anchors

Who is this standard for?

  • Contractors – specialist anchor contractors, procurement officers, project managers, design managers, construction managers, construction engineers, planning engineers
  • Consultants engaged in ground anchor design, construction, testing, monitoring and maintenance 
  • Consulting engineers – geotechnical and civil engineers, structural engineers, project managers, design engineers, site resident engineers, site supervising engineers
  • Geo-environmental specialists and geologists
  • Designers – architects, design engineers, project managers
  • Manufacturers – specialist anchor component manufacturers, technical managers, project managers.   

Why should you use this standard?

It establishes specifications for the execution of tension tests to be carried out on an anchor grouted in the ground, as defined in BS EN 1997-1:2004+A1:2013 and EN 1537:2013. 

Such anchors can be used to provide support to retaining structures subject to horizontal load, basements subject to uplift, and many other geotechnical structures.

The standard describes three test types that are associated with three test methods:

  • Method 1 involves cyclic tension loading with measurement of displacement at the load stages
  • Method 2 involves cyclic tension loading with measurement of loss at the load stages
  • Method 3 involves step-loading with measurement of displacement under successive maintained tension loads.

Test methods 1, 2 and 3 shall be used consistently for all test types i.e. investigation, suitability and acceptance.

The standard also provides specifications for experimental devices, measurement apparatus, test procedures, the definition and presentation of the test results and the content of records. 

NOTE: This standard does not provide specifications for the size of the proof load and the limiting criteria. These are in the UK National Annex to BS EN 1997-1.
