EN 1317 European Standard
The EN 1317 European standard was developed within the framework of the Construction Products Directive 89/106/EEC.
The EN 1317-5 standard (Product requirements, durability and evaluation of conformity) serves as a basis for the CE marking of road safety systems such as safety barriers and guardrails, crash cushions, barrier extremities and transitions.
In order to get this CE mark, road safety systems must be tested following the requirements described in the here-under technical standards which describe the crash test conditions.
- EN 1317-1 : Terminology and general criteria for test methods
- EN 1317-2 : Performance classes, impact test acceptance criteria and test methods for safety barriers
- EN 1317-3 : Performance classes, impact test acceptance criteria and test methods for crash cushions
- EN 1317-4 : Performance classes, impact test acceptance criteria and test methods for terminals and transitions of safety barriers
As an example, the test conditions for safety barriers, described in part 2, are here-under described.
Within the context of this standard the crash tests require various vehicle types like cars, trucks ranging from 10 tonnes to 38 tonnes and coaches and must be performed following these conditions.
The standard defines several containment levels for safety barriers, depending on the vehicle type to be restrained. For one barrier of a given containment level, one or two crash tests must be conducted.
