This standard BS EN 13391:2004 Mechanical tests for post-tensioning systems is classified in these ICS categories:
91.080.40 Concrete structures
This European Standard specifies the test procedures for the anchorages and couplings of post-tensioning systems. This standard is to be used in conjunction with the relevant European Standards ENV 1992-1-1 and ENV 1992-2 and others for pertaining to prestressed concrete structures. The test results should be used for the acquisition of the Technical Approval of the specified post-tensioning system. For unbonded tendons additional tests and requirements are needed and these are not covered in the present scope of this standard.
