Foreword
This European Standard was prepared by the CENELEC BTTF 63-2, Advanced technical ceramics.
The text of the draft was submitted to the formal vote and was approved by CENELEC as EN 50324-1 on
2001-12-01.
The following dates were fixed:
– latest date by which the EN has to be implemented
at national level by publication of an identical
national standard or by endorsement (dop) 2002-12-01
– latest date by which the national standards conflicting
with the EN have to be withdrawn (dow) 2004-12-01
This draft European Standard consists of three parts:
Part 1 Terms and definitions
Part 2 Methods of measurement - Low power
Part 3 Methods of measurement - High power

Introduction
The principles underlying the piezoelectricity of ceramics are discussed in IEC 60483 “Guide to
dynamic measurements of piezoelectric ceramics with high electromechanical coupling”. Piezoelectric
ceramics are polycrystalline ferroelectrics mainly based on lead zirconate titanate (Pb(ZrTi)O ), barium
3
titanate (BaTiO ) and lead titanate (PbTiO ). Their piezoelectricity is the result of the preferential
3 3
orientation of polar regions at remanent polarisation. In ceramics, the remanent polarisation is created
by application of a dc electric field to the polycrystalline material. The value of this remanent
polarisation results in the high level of piezoelectric
