TS EN 1317-1

TS EN 1317-1 is the standard that sets the terminology and the general criteria used for test methods in road restraint systems, with a focus on how products are assessed under impact conditions. In general technical terms, road restraint systems are the roadside and median safety devices intended to influence the movement of errant vehicles and manage the consequences of a collision in a controlled way.

Why the terminology matters

For this subject area, common terminology is essential because the same physical event can be described differently unless the performance language is standardised. The standard provides a shared framework for talking about impact behaviour and for organising test methods around comparable conditions and severity levels. As general engineering context, this helps manufacturers, test laboratories and specifiers interpret results consistently when a road safety product is evaluated for how it behaves under collision loading.

What this part covers

• It contains provisions for measuring the performance of products used in road restraint systems under impact and impact severity levels.
• It addresses terminology and general criteria for test methods rather than the full detailed design of every product type.
• Its role is to support consistent interpretation of test results across road restraint applications.
• More specific product performance requirements may be set out in other parts of the EN 1317 series.
