IEC 61300-3-25:2016 describes the procedure to determine the concentricity of the axis of the bore in a non-angled ferrule with the axis of the ferrule, and in the case of non-angled ferrules with fibre installed, to determine the concentricity of the axis of the fibre core with the axis of the ferrule. This third edition cancels and replaces the second edition published in 2013 and constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
- deletion of method C due to potential damage of ferrule end face by the spindle. Method C is the ferrule bore reference method for bare ferrules according to IEC 61300-3-25:2013;
- separation of original method A into method A-1 and method A-2 relating to the two different types of ferrule (with/without fibre fitted);
- integration of the content of Annexes A and B into the test procedure. Keywords: concentricity, ferrule
