Foreword
This European Standard (EN 725-8:2006) 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shall be withdrawn at the latest by September 2006.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 725-8:1997.
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;
- modifications to the test report requirements.
EN 725 Advanced technical ceramics — Methods of test for ceramic powders was prepared in Parts
as follows:
Part 1: Determination of impurities in alumina
Part 2: Determination of impurities in barium titanate
Part 3: Determination of oxygen content of non-oxides by thermal extraction with a carrier gas
Part 4: Determination of oxygen content in aluminium nitride by XRF analysis
Part 5 Determination of particle size distribution
Part 6: Determination of specific surface area [withdrawn]
Part 7: Determination of absolute density [withdrawn]
Part 8: Determination of tapped bulk density
Part 9: Determination of un-tapped bulk density
Part 10: Determination of compaction properties
Part 11: Determination of densification on natural sintering
Part 12: Chemical analysis of zirconia
Parts 6 and 7 of the series were superseded in 2005 by EN ISO 18757 and EN ISO 18753
respectively.
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the
following countries are bound to implement this European Standard: Austria, Belgium, Cyprus, Czech
