This European Standard shall be given the status of a national standard, either by publ
21、ication of an identical text or by endorsement, at the latest by January 2014, and conflicting national standards shall be withdrawn at the latest by January 2014. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC
22、 shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 1537:1999. The remit of CEN/TC 288 is the standardisation of the execution procedures for geotechnical works (including testing and control methods) and of the required material properties. CEN/
23、TC 288/WG 14 has been charged with the revision of EN 1537:1999 in the subject area of ground anchors, which includes all anchors that are bonded to the ground by grout and are stressed and tested. This standard has been prepared to stand alongside EN 1997-1, Eurocode 7: Geotechnical design Part 1:
24、General rules, and prEN ISO 22477-5, Geotechnical investigation and testing Testing of geotechnical structures Part 5. Design, safety aspects and testing, which were included as the informative Annexes D and E in the previous issue of this standard (EN 1537:1999), were consequently taken out of this
