This European Standard was approved by CEN on 6 July 2002.
CEN members are bound to comply with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this European
Standard the status of a national standard without any alteration. Up-to-date lists and bibliographical references concerning such national
standards may be obtained on application to the Management Centre or to any CEN member.
This European Standard exists in three official versions (English, French, German). A version in any other language made by translation
under the responsibility of a CEN member into its own language and notified to the Management Centre has the same status as the official
versions.
CEN members are the national standards bodies of Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece,

Foreword
This document (EN 1007-3:2002) 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by endorsement, at the latest by March 2003, and conflicting national standards shall be withdrawn at the latest by
March 2003.
This document supersedes ENV 1007-3:1993.
EN 1007 has six parts:
EN 1007-1 Part 1: Determination of size content.
EN 1007-2 Part 2: Determination of linear density.
EN 1007-3 Part 3: Determination of filament diameter and cross-section area.
prEN 1007-4 Part 4: Determination of tensile properties of filament at ambient temperature.
prEN 1007-5 Part 5: Determination of distribution of tensile strength and of tensile strain to failure of
filaments within a multifilament tow at ambient temperature.
ENV 1007-6 Part 6: Determination of tensile properties of filament at high temperature.
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following
countries are bound to implement this European Standard: 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 part of the European Standard specifies the conditions for the determination of the diameter and cross-section
area of ceramic single filament, as used in fibre reinforcement of ceramic composites for three methods.
NOTE The cross-sectional area of filaments from different suppliers will vary significantly. The term “diameter” applies both
to circular cross-section (“true diameter”) and non-circular cross-sections (“apparent diameter”).
2 Principle
The diameter and cross-section area of the ceramic filament may be measured by three methods, as follows:
a) the longitudinal profile method (Method A), whic
