This European Standard was approved by CEN on 28 November 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.
CEN members are the national standards bodies of Austria, Belgium, Cyprus, Czech Republic, Denmark, Estonia, Finland, France,
Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Slovakia,

Foreword
This European Standard (EN 14808:2005) has been prepared by Technical Committee CEN/TC 217 “Surfaces for
sports areas”, 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by endorsement, at the latest by June 2006, and conflicting national standards shall be withdrawn at the latest by
June 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 European Standard specifies a method for the determination of shock absorption characteristics of sports
surfaces.
NOTE The method specified is commonly known as the Artificial Athlete (Berlin) method.
2 Normative references
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 document
(including any amendments) applies.
EN 12229, Surfaces for sports areas — Procedure for the preparation of synthetic turf and textile test pieces
ISO 6487, Road vehicles — Measurement techniques in impact tests — Instrumentation
3 Terms and definitions
For the purposes of this European Standard, the following terms and definitions apply.
3.1
area-elastic sports surface
sports surface, to which the application of a point force causes deflection over a relatively large area around the
point of application of the force
3.2
point-elastic sports surface
sports surface, to which the application of a point force causes deflection only at or close to the point of application
of the force
3.3
combination-elastic sports surface
area-elastic sports surface with a point-elastic top layer, to which the application of a point force causes both
localized deflection and deflection over a wider area
3.4
mixed-elastic sports surface
point-elastic sports surface with an area-stiffening component
NOTE A mixed-elastic sports surface has deflection characteristics between those of an area-elastic surface and a point-
elastic surface.
3.5
shock absorption
ability of a sports surface to reduce the impact force of a body falling onto the surface
NOTE Shock absorption is a physical quantity consisting of damping and resilience due to a certain impact.
4 Principle
A weight is allowed to fall onto a spring placed on the test piece and the maximum force applied is recorded. The
difference between this force and the maximum force measured on a hard surface is reported as the force
reduction.
