Dear Marc,
Yes. We have been using this standard for auditing (internal) our ISO-14001 systems for quite sometime (from the beginning of 2003). I understand that this is a requirement (to use a standard for auditing) of IAF. Hence I had trained many internal auditors in our units (ISO-14001 certified) during Q-1 2003 to enable them to implement the standard.
With best regards,
Ramakrishnan
