UNE-EN ISO 22477-5:2019

(1) This Standard establishes specifications for the execution of tension tests to be carried out on an anchor grouted inthe ground, as defined in EN 1997-1 and EN 1537. Three methods of testing are recognised by this Standard. Method1 involves cyclic tension loading with measurement of displacement at the load stages. Method 2 involves cyclictension loading with measurement of loss at the load stages and Method 3 involves step-loading with measurement ofdisplacement under successive maintained tension loads.(2) The standard provides specifications for three types of tension tests as defined in EN 1997-1 and EN 1537:investigation tests, suitability tests and acceptance tests.(3) Test methods (1, 2 or 3) shall be used consistently for all test types (Investigation, Suitability and Acceptance).(4) The standard provides specifications for the experimental devices, the measurement apparatus, the testprocedures, the definition and the presentation of the test results and the content of records.(5) The standard does not provide specification for the size of the proof load and the limiting criteria. These shall bestated in EN 1997-1 or its national annex for CEN countries and in similar national application documents for this teststandard for ISO countries.
