What is the EN1317?

EN 1317 is a European Norm etablished in 1998 that defines common testing and certification procedures for road restraintsystems.   The use of the CE marking coming from its part 5 is mandatory for each EU nation as from January 2011.

It’s important to point out that EN1317 do not states which barriers should be used in one or another situation, but it states which test a product should undergo to be in a certain performance class and what are the safety levels (ASI, THIV, etc..) and the classes of performance (based on different parameters).
