[vc_row column_spacing=”20″][vc_column][vc_column_text]Performance evaluation and Classification of Vehicle Restraint Systems (VRS)<\/strong><\/p>\n

From January 1st<\/sup>, 2011 it is mandatory that all vehicle restraint systems installed permanently on the roads of the European Community have the marking. To obtain such Certification, it is necessary to proceed in accordance with the specifications of the harmonized standard UNE EN-1317. This standard classifies and evaluates the performance of the vehicle restraint systems by means of full-scale crash tests.<\/p>\n

VRSs must be installed under conditions similar to those applied in the test and complying with the specifications in the Manufacturer’s Installation Manual.<\/p>\n

The parameters that determine the qualities of a vehicle restraint system and classify it within the standard EN 1317 are: the containment level, the working width, the dynamic deflection and the impact severity.<\/p>\n

\u2022 Containment Level: <\/strong><\/span>It indicates the capacity of a containment system to withstand the impact load of a vehicle.<\/p>\n

\u2022 WORKING WIDTH (W): <\/strong><\/span>It is the distance between the traffic face of the restraint system before the impact, and the furthest lateral position reached by any essential part of the restraint system and the vehicle.<\/p>\n

\u2022 Redirection: <\/span>This is the capacity of a restraint system to return a vehicle to the road in a controlled manner after an impact against such restraint system.[\/vc_column_text][vc_empty_space][vc_single_image image=”8693″ img_size=”750×387″ alignment=”center”][vc_empty_space][vc_column_text]CEN Box: Zone which the vehicle may not leave during its exit trajectory after an impact against a restraint system. The system will be certified only if the test ends with the vehicle inside the CEN box.<\/strong><\/p>\n

Conclusions:<\/p>\n

\u2022Containment Level:<\/span><\/p>\n

We guarantee that the system contains the vehicle (no intrusion, no rollover)<\/p>\n

\u2022 Impact severity:<\/span><\/p>\n

We guarantee low decelerations.<\/p>\n

\u2022 System deformation:<\/span><\/p>\n

We guarantee that neither the vehicle nor the system will impact against other obstacles, and that the vehicle will not fall down a slope.<\/p>\n

\u2022 Redirection:<\/span><\/p>\n

We guarantee that the vehicle will not invade other lanes.[\/vc_column_text][\/vc_column][\/vc_row]\n<\/div>","protected":false},"excerpt":{"rendered":"
