EN 13817:2005 – Surfaces for sports areas
1 Scope
This document describes a procedure for subjecting test pieces taken from surfaces for sports areas to accelerated ageing by exposure to hot air in the laboratory. Test pieces are aged to permit a comparison of their physical characteristics before and after ageing in accordance with European Standard test methods for surfaces for sports areas.
This method is suitable for ageing all types of sports surfaces, except for wooden surfaces, using test pieces in the laboratory, but is primarily intended for ageing polymeric surfaces. The procedure allows a measure of the effect on the physical characteristics of the sports surface due to exposure to hot air to be made.
NOTE Resuts on materials which exhibit temporary changes in properies due to drying should be interpreted with caution,

ISO 188:1998, Rubber, vulcanized or thermoplastic – Accelerated ageing and heat resistance tests
3 Principle
Test pieces are exposed to air at an elevated temperature to permit selected physical characteristics of the surface to be assessed before and after test.
4 Apparatus
4.1 Air circulating oven, as described in ISO 188:1998, 3.2.2.
5 Test pieces
Select, prepare and conditin the test piece(s) in accordance with the appropriate method of test.
Test pieces shall be such that no mechanical, chemical or heat treatment will be required after their removal from the oven.
Any material used for marking test pieces shall not be applied in any critical area of the test piece and shall not damage the surface or be destroyed during ageing.
NOTE
Wherever possible, marking should be caried out after ageing of the test pliece.
6 Procedure
Place the test pieces in the oven (4.1) after it has been pre-heated to a temperature of (70土2)*C. The test pieces shall be stationary, free from strain and freely exposed to air on all sides and not exposed to light.
Leave the test pieces in the oven for (336 +2) h.
