This European Prestandard (ENV) was approved by CEN on 11 April 2002 as a prospective standard for provisional application.
The period of validity of this ENV is limited initially to three years. After two years the members of CEN will be requested to submit their
comments, particularly on the question whether the ENV can be converted into a European Standard.
CEN members are required to announce the existence of this ENV in the same way as for an EN and to make the ENV available promptly
at national level in an appropriate form. It is permissible to keep conflicting national standards in force (in parallel to the ENV) until the final
decision about the possible conversion of the ENV into an EN is reached.
CEN members are the national standards bodies of Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece,
Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and United Kingdom.

Foreword
This document (ENV 14273:2002) has been prepared by Technical Committee CEN/TC 184
"Advanced technical ceramics", the secretariat of which is held by BSI.
Annex A is normative.
This Prestandard includes a Bibliography.
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the
following countries are bound to announce this European Prestandard: Austria, Belgium, Czech
Republic, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Malta,
Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom.
1 Scope
This European Prestandard specifies a method for the routine qualitative and quantitative
determination of the crystalline phases (monoclinic, tetragonal and cubic) present in zirconia powders
using X-ray powder diffraction.
2 Normative references
This European Prestandard incorporates by dated or undated reference provisions from other
publications. These normative references are cited at the appropriate places in the text and the
publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of
these publications apply to this European Prestandard only when incorporated in it by amendment or
revision. For undated references the latest edition of the publication referred to applies (including
amendments).
