EN 1317-2:2010 (E) 6 Introduction This European Standard is a revision of EN 1317-2:1998. This standard includes improved impact test procedures and allows for the introduction of Families of Products and a report template. In order to improve safety the design of roads may require the installation of safety barriers including vehicle parapets which are intended to contain errant vehicles safely for the benefit of the occupants and other road users on sections of road and at particular locations defined by the national or local authorities. In this standard, several levels of performance are given for the three main criteria relating to the restraint of a road vehicle:  The containment level;  The impact severity levels;  The deformation as expressed by the working width and vehicle intrusion (including normalised values). The different performance levels of safety barriers including vehicle parapets will enable national and local authorities to specify the performance class of the system to be deployed.

The description of a safety barrier including vehicle parapet system conforming to this standard incorporates the relevant classes and performance levels of the product. To ensure satisfactory product design it is highly recommended to consider the requirements of this standard and the references in Clause 2, together with the requirements of EN 1317-1. The evaluation of conformity and the durability should meet the requirements of EN 1317-5. SIST EN 1317-2:2010

EN 1317-2:2010 (E) 7 1 Scope This European Standard specifies requirements on impact performance of safety barriers, including vehicle parapets, classes of containment, working width, vehicle intrusion and impact severity levels. NOTE This European Standard should be read in conjunction with EN 1317-1. Both these standards support EN 1317-5. The modifications included in standard are not a change of test criteria, in the sense of the

Temporary safety barriers can also be tested for higher levels of containment. NOTE 2 A successfully tested barrier at a given containment level should be considered as having met the containment requirements of any lower level, except that N1 and N2 do not include T3, H-Levels do not include L-Levels and that H1, ..., H4b do not include N2. NOTE 3 Because testing and development for very high containment safety barriers in different countries has taken place using significantly different types of heavy vehicles, both tests TB 71 and TB 81 are included in the standard at present. The two containment levels H4a and H4b should not be regarded as equivalent and no hierarchy is given between them. The same holds for the two containment levels L4a and L4b. NOTE 4 The performance of Containment Classes L is enhanced in respect to the corresponding H classes by the addition of Test TB 32.

The evaluation of a vehicle restraint system within the range of containment levels T3, N2, H1, H2, H3, H4a, H4b, L1, L2, L3, L4a and L4b shall require the carrying out of different tests: a) A test according to the maximum level of containment for that particular system; and SIST EN 1317-2:2010

EN 1317-2:2010 (E) 9 b) Test(s) using cars in order to verify that satisfactory containment of the maximum level is also compatible with safety for a range of cars. 3.3 Impact severity The evaluation of vehicle occupant impact severity assessment indices ASI and THIV shall be carried out for cars. For cars ASI and THIV shall conform to the requirements of Table 3.

These indices are defined in EN 1317-1:2010. As a function of the value of the ASI and THIV indices, three impact severity classes A, B and C are defined in Table 3.

Impact severity level A affords a greater level of safety for the occupant of an errant car than level B, and level B greater than level C. Test measures, appropriately adjusted in accordance with EN 1317-1:2010, 6.3, shall be directly compared to the values in Table 3. Table 3 — Impact severity levels Impact severity level Index values A ASI ≤ 1,0 and THIV ≤ 33 km/h B ASI ≤ 1,4 C ASI ≤ 1,9

3.4 Location of the ATD The ATD, when required by EN 1317-1, shall be located in the front seat of the car on the impact side and secured by means of the vehicle seat belt. 3.5 Deformation of the restraint system The deformation of safety barriers during impact tests is characterised by the dynamic deflection, working width and vehicle intrusion (see Figure 1). The accuracy required for the measurement of the dynamic deflection and for the working width shall be 10 % but not less than 0,1 m. The measurement shall be recorded in metres (m) to at least two decimal places and reported to one decimal place by mathematical rounding, i.e. 0,64 = 0,6; 0,65 = 0,7. The rounded value of the working width shall not be allowed to become smaller than the real width of the safety barrier. In this case the value shall to be rounded up; e.g. System width = 0,63 m, Wnormalized = 0,64 m, then Wrounded = 0,7 m. The dynamic deflection (Dm) shall be the maximum lateral dynamic displacement of any point of the traffic face of the restraint system. SIST EN 1317-2:2010

EN 1317-2:2010 (E) 10 The working width (Wm) is the maximum lateral distance between any part of the barrier on the undeformed traffic side and the maximum dynamic position of any part of the barrier. If the vehicle body deforms around the road vehicle restraint system so that the latter cannot be used for the purpose of measuring the working width, the maximum lateral position of any part of the vehicle shall be taken as an alternative (see Figure 1, d)).

The vehicle intrusion (VIm) of the Heavy Goods Vehicle (HGV) is its maximum dynamic lateral position from the undeformed traffic side of the barrier; it shall be evaluated from high speed photographic or video recordings, in consideration of a notional load having the width and length of the vehicle platform and a total height of 4 m. The VIm shall be evaluated by measuring the position and angle of the vehicle platform and assuming the notional load stays undeformed and rectangular to the vehicle platform or by using test vehicles with the notional load. The vehicle intrusion (VIm) of a bus is its maximum dynamic lateral position; it shall be evaluated from high speed photographic or video recordings.

The deformation of the restraint system shall be classified in accordance with Tables 4 and 5. The actual and normalised values of dynamic deflection, working width and vehicle intrusion shall be measured and recorded in the test report.

See Table 1. Specified Angle in degrees (°) = .t;

With the above procedure, the Normalised Dynamic Deflection and Normalised Working Width shall be computed from measured data, or from other test data recorded during tests performed before the publication of the present standard, provided the data collection methods conform to the requirements of this standard.

Likewise, Vehicle Intrusion shall be evaluated, from high speed photographic or video recordings, and then normalised using measured data.

The accuracy required for the evaluation of Vehicle Intrusion shall be ± 0,2 m. SIST EN 1317-2:2010

The test parameters on which acceptance criteria shall be assessed are listed in Table 6 as a function of the containment level. When during a test, after the end of the impact subsequent collisions of the vehicle with the safety barrier including vehicle parapet occur, these subsequent collisions shall not be considered for performance or acceptance.

All parameters of Table 6 shall be reported and the worst case shall be used to define the classes. 4.2 Safety barrier including vehicle parapet behaviour

The safety barrier including vehicle parapet shall contain the vehicle without complete breakage of any of the principal longitudinal elements of the system. All totally detached parts of the safety barrier with a mass greater than 2,0 kg shall be identified, located and recorded in the test report with their size. This information can be used to define sites where the barriers with detached parts shall not be used to provide safety for people behind the barrier.
