Foreword
This European Standard (EN 725-9:2006) has been prepared by Technical Committee CEN/TC 184
“Advanced technical ceramics”, the secretariat of which is held by BSI.
This European Standard shall be given the status of a national standard, either by publication of an
identical text or by endorsement, at the latest by September 2006, and conflicting national standards
shall be withdrawn at the latest by September 2006.
This European Standard supersedes EN 725-9:1997.
The main changes in the new edition are:
- revision of the Foreword to reflect changes in the EN 725 series;
- addition of normative references;
- modifications to the apparatus specification;
