NOTE    This European Standard does not invalidate existing approvals of products achieved on the basis of national standards and specifications and/or the demonstration of satisfactory service performance

Why should you use ISO 11665‑6

the preparation of laboratory sheets for testing the physical properties follows the procedures described in ISO 5269-1 (conventional sheet former) or ISO 5269-2 (Rapid-Köthen sheet former)

NOTE 6 Future technological development of transformers may necessitate a need to increase the upper limit of the frequencies
