Containment level

The level of containment is characterized by the degree of resistance of the collision barrier depending on the total weight of the vehicle, the angle of impact and the speed of impact according to the collision test in accordance with EN 1317 (see table).

Table ' EN 1317 classification of containment levels '

Containment levels are determined by the tests that must be tolerated by the above limits. Each new system must be tested at least twice – one time with a light vehicle, to determine the impact and influence of the car driver and the second time with a heavier vehicle in order to determine the maximum impact energy that the test limiting system could absorb. Safety levels are classified according to the impact energy that has been tested on the system.

In order to obtain the CE marking and the authorisation for marketing in the European Union, collision tests must be carried out on the perimeter system. The test-limitation system shall conform to the following parameters:

• The collision shall be directed to the vehicle back on the road without full breakup of the barrier;
• The Bounde details must not penetrate the car occupers ' space;
• Deformities, which may endanger the life of road users, are not permitted;
• The gravitational gravity of the vehicle shall not exceed the deformed system centimeters;
• The vehicle must not be displaced as a result of the collision;
• In the case of heavy vehicle tests, no more than 5% of the vehicle's load may fall;
• In addition to the limits of exposure, the vehicle must not swell to the oncoming zone.
