My first encounter with "Standards" was over 25 years ago when I joined a working group which was to write the first generation of documents for what was much later to become known as "Modal Testing."

That project had disclosed the existence of a wide range of skills and practices in the community which suggested that many impedance measurements were of doubtful reliability. As a result, it was decided that some sort of reference documentation was called for, a Standard no less. That was the task to which I, as a young researcher, came eager to contribute.
