5 Requirements determined by laboratory testing
5.1 Specimens used for laboratory testing
The laboratory tests described in 5.2 to 5.5 and 5.7 shall be carried out using a supporting element e.g. a
reinforced concrete block to represent concrete ballastless track or a steel plate to represent a steel
bridge structure.
For continuously supported rail, the test length of rail is the length which is supported on the pad. For
embedded rail, the test length of rail is the length which is embedded. In these cases, for category A the
test length should be (0,8 ± 0,01) m and for categories B to D the test length should be (0,6 ± 0,01) m.
The supporting element shall have a rail seat inclination no greater than the inclination to be used on the
application for which the type of fastening will be used.
For example, a fastening tested successfully on a support with 1:40 inclination does not need to be re-
