TS EN 1317-1

TS EN 1317-1 defines the terminology and the general criteria for test methods used for road restraint systems. It provides a common technical basis for understanding how the performance of road safety devices is described and how impact testing is framed at a general level. In road infrastructure, restraint systems are used to manage crash energy, limit vehicle departures from the roadway, and reduce risks to road users and surroundings during an impact.

Terminology and performance in a single technical framework

The main value of this kind of standard is to align the language used for different products and systems. Road restraint systems, including barriers, guardrails, terminals and related devices, are identified not only by their physical form but also by their crash behaviour, deformation characteristics and influence on vehicles. Clear terminology makes test results easier to interpret and technical documentation easier to compare.

General criteria for test methods

The scope information supplied for this document indicates that it addresses the measurement of product performance under impact and impact severity levels. In general technical context, this means the standard belongs to the family of documents used to describe how road safety products are assessed under controlled collision conditions. It should be read as a general framework for test approach rather than as a product-specific standard defining numeric limits or detailed step-by-step procedures.

For road restraint systems, a reference of this kind supports engineering design, comparison of laboratory and field testing, and the use of a consistent reporting language. In highway safety practice, that shared terminology and testing logic are essential when selecting and evaluating roadside protection systems.
