Foreword
This document (EN 725-2:2007) 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text or by endorsement, at the latest by May 2008, and conflicting national standards shall be withdrawn at the
latest by May 2008.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights.
This document supersedes ENV 725-2:1994.
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 the 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Part 6: Determination of the specific surface area [withdrawn]
Part 7: Determination of the absolute density [withdrawn]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
Part 6 and part 7 of this series were superseded in 2005 by EN ISO 18757 and EN ISO 18753.
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following
countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Cyprus, Czech
