This European Standard was approved by CEN on 1 July 2005.
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 Central Secretariat 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 Central Secretariat has the same status as the official
versions.

Foreword
This European Standard (EN 14882:2005) has been prepared by Technical Committee CEN/TC 248 “Textiles
and textile products”, 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text or by endorsement, at the latest by February 2006, and conflicting national standards shall be withdrawn
at the latest by February 2006.
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 Republic,
Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania,
Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Slovakia, Slovenia, Spain, Sweden, Switzerland
and United Kingdom.
1 Scope
This test method details a method of assessing the frictional property of coated fabrics. The test consists of
measuring the force necessary to move a sled on the surface of coated fabric test specimen and determining
the static and dynamic coefficient of friction.

The following referenced documents are indispensable for the application of this European Standard. For
dated references, only the edition cited applies. For undated references, the latest edition of the referenced

3 Terms and definitions
For the purposes of this European Standard, the following terms and definitions apply.
3.1
coefficient of static friction (µ )
s
coefficient calculated from the ratio of the force necessary to cause the tangential separation of two stationary
surfaces to the perpendicular force acting upon the two surfaces
3.2
coefficient of dynamic friction (µ )
d
coefficient calculated from the ratio of the force necessary to maintain a constant velocity between two
surfaces in contact to the perpendicular force acting upon the two surfaces
4 Principle
A sled is attached to a strain gauge and is linked to an autographic recording device The sled is caused to
move against the test specimen which is either rigidly mounted on a horizontal bed or the base of the sled.
The force to initiate the movement of the sled and thereafter maintain a constant velocity is measured.
From specific forces, the coefficients of friction (static and dynamic) a
