Safety guardrails must comply with the EN1317 standard and must be CE certified by an approved certification body (ASCQUER or equivalent).
The CE marking guarantees the product’s compliance with the EN1317 standard in terms of performance criteria and traceability. The CE marking does not guarantee the product’s durability; only the manufacturer is authorized to provide its own warranty. Rondino offers high-durability safety products. Our wood is Class 4 Pine, and the high-performance steel is hot-dip galvanized to ensure the highest quality.
The ASI (Acceleration Severity Index) measures the severity of the impact for vehicle occupants.
Level A provides the highest level of safety.
| CLASS | ASI | VALUE |
| A | LOW | ASI ≤ 1,0 |
| B | MEDIUM | 1 < ASI ≤ 1,4 |
| C | HIGH | 1,4 < ASI ≤ 1,9 |
Working width (Wn), Dynamic deflection (Dn), Vehicle intrusion (Vin)
Vehicle intrusion represents the maximum dynamic lateral position of the vehicle relative to the traffic-facing side of the barrier.
The European standard classifies Vi values into different classes from VI1 to VI9.
| Standardised vehicle intrusion level classes | Standardised vehicle intrusion levels (m) |
| VI1 | VIn ≤ 0,6 |
| VI2 | VIn ≤ 0,8 |
| VI3 | VIn ≤ 1,0 |
| VI4 | VIn ≤ 1,3 |
| VI5 | VIn ≤ 1,7 |
| VI6 | VIn ≤ 2,1 |
| VI7 | VIn ≤ 2,5 |
| VI8 | VIn ≤ 3,5 |
| VI9 | VIn ≥ 3,5 |
NOTE 1: In specific cases, a vehicle intrusion level class lower than VI1 may be specified.
NOTE 2: Dynamic deflection, working width, and vehicle intrusion make it possible to determine the installation conditions for safety barriers and to define the distances to be maintained in front of obstacles.
RONDINO is a member of the French standardization committee at BNTRA – Road restraint systems (RRS).
RONDINO also participates in the working group of the European Commission TC226/WG1 for the development and revision of the European EN1317 standards.
