Overview

EN 1317-3:2010 - Road restraint systems, Part 3 - specifies the performance classes, impact test acceptance criteria and test methods for crash cushions used on European roads. Published by CEN, this standard defines how crash cushions must perform during vehicle impacts, the severity indices to be measured, and the test program required for product acceptance. EN 1317-3:2010 is intended to be read in conjunction with EN 1317-1 (terminology and general test criteria) and EN 1317-5 (product requirements and conformity).

Key topics and technical requirements

• Performance classes: Defined levels (50, 80, 100, 110) based on increasing energy absorption and specified vehicle impact tests.
• Impact tests (Table 1): Matrix of test conditions using representative vehicle masses (e.g., ~900 kg, 1 300 kg, 1 500 kg) and speeds from 50 to 110 km/h, plus frontal and lateral approaches (including 15° angles).
• Severity indices: Mandatory measurement of ASI (Acceleration Severity Index) and THIV (Theoretical Head Impact Velocity) to rate occupant impact severity. Severity levels A and B are defined (e.g., A: ASI ≤ 1.0 and THIV ≤ 44 km/h for frontal tests; THIV ≤ 33 km/h for lateral tests).
• Crash cushion types: Redirective (R) - contain and redirect vehicles; Non-redirective (NR) - contain but do not redirect.
• Families of crash cushions: Rules for parent and derivative models allowing a reduced test matrix when models share components, mechanism and product identity.
• Test tolerances and methods: Includes tighter angle tolerance (±1° introduced), combined speed/angle deviation limits for side tests, and the new measurement VCDI (introduced in this revision).
• Acceptance criteria & reporting: Behaviour limits for crash cushion and vehicle, lateral displacement, deformation limits, and a normative Annex A - Detailed Test Report Template.

Applications

• Selection and specification of crash cushions for motorways, interchanges, work zones, and roadside hazards.
• Product type-approval testing and performance verification for manufacturers.
• Design guidance for road safety engineers to meet required occupant protection levels.
• Procurement criteria for authorities and contractors installing roadside protective devices.

Who uses this standard

• Road authorities and infrastructure owners
• Crash cushion and barrier manufacturers
• Accredited test houses and laboratories
• Road safety engineers, designers and consultants
• Contractors, procurement teams and conformity assessment bodies

5.6 Families of crash cushions A family of crash cushion models shall be derived from a single parent crash cushion once the latter has been successfully tested to this standard.
A reduced matrix of tests shall be completed for the other family members in accordance with Tables 4 to 9. The models in the family cover a range of performance classes, width and taper angles.
Provided that the models in the family: a) are assembled from the same set of components; b) have the same product name; c) have the same working mechanism for the system and for the components, the family, specified by the drawings of all the models, can be tested as a single product with multiple performance levels. If the tests specified by the family test matrix are passed, the crash cushion is accepted as a multiple performance product, i.e. each model is accepted in the relevant performance class. All the cushions in the family shall be of the same type, i.e. all redirective or all non-redirective. If the parent crash cushion has the minimum taper angle/width and belongs to the highest performance class, the test matrix is the one shown in Table 4, 5, 6 or 7, depending on the highest velocity of the family.
