This European Standard specifies requirements for evaluation of conformity of the following vehicle restraint systems:
a)   safety barriers;
b)   crash cushions;
c)   terminals (will be effective when ENV 1317-4 becomes an EN);
d)   transitions (will be effective when ENV 1317-4 becomes an EN);
e)   vehicle / pedestrian parapets (only for the vehicle restraint function).
Pedestrian parapet requirements are not covered in this document.
Requirements for the evaluation of durability with respect to weathering are included in this document.
Requirements for other forms of durability (e.g. marine environment, sand abrasion) are not included.
Temporary barriers are not within the scope of this document.

Annex C
(normative)
Resistance to snow removal
C.1 General

Snow removal may damage a safety barrier which has not a sufficient resistance to snow removal.

C.2 Scope

This normative annex includes a classification of safety barriers for the resistance to snow removal.

It includes the horizontal and vertical pressure of ploughed snow against the rail and minor impacts

caused by the plough in the traffic face and upper edge of the rail. A simplified evaluation method

is intended for normal steel beam barriers, rope fences and monolithic pre-cast or cast-in-place

concrete barriers. A test is possible for other barrier types.
The specifying authority shall decide if classification is required.

This annex is not intended to be used with crash cushions, terminals and transitions.

EN 1317-5:2007+A1:2008/FprA2:2011(E)
C.3 Requirements

Metal beam safety barriers shall be classified into classes on the basis of Table C.1.

Table C.1 - Resistance to snow removal of metal beam safety barriers
Class of Modified material Modified section Strength against

a a

3 ≥ 3 ≥ 2,2 ≥ 5 ≥ 9 > Shear strength
of M10 4,6 bolt
2 Rope fence
1 Other
The modified material thickness and section modulus is defined in C.4.

In class 3 and 4 the front edge of the rail shall protrude at least 40 mm in front of the post in order

to protect posts. There shall be no bolts or roughness on the rail, which could prevent the snow

plough from gliding along the barrier. The requirements for the modified section modulus in

Table C.1 shall be reduced by 50 % for narrow rails (< 120 mm) which do not have contacts with

snow plough.

Pre-cast or cast-in-place monolithic concrete barriers shall be declared to belong to class 4, when

the strength class is C 25/30 or higher. Any unevenness in the traffic face shall not prevent the

snow plough from gliding along the barrier.

In class 2 the longitudinal parts of the barrier shall be designed to remain undamaged in an impact

by a snow plough, but post may be fully damaged.
C.4 Evaluation
C.4.1 Modified material thickness

The modified material thickness shall be calculated by using the following equation:

2 1/2
t = t x[ f /(235N/mm /1.1)] (1)
mod yd
where
t is the modified material thickness of the rail;
mod
t is the nominal steel thickness of the rail;
f is the design yield strength of the rail material.
The nominal material thickness of the rail shall be observed from the drawings.

EN 1317-5:2007+A1:2008/FprA2:2011(E)
C.4.2 Modified section modulus

The modified section modulus of the post and rail against horizontal loads shall be calculated on

the basis of the post and rail profile by using the following equations:
= W x f /(235N/mm/1.1) (2)
mod, rail rail yd
W = W x f /(235N/mm/1.1) (3)
mod, post post yd
where
W is the modified section modulus of the rail;
mod, rail

W is the original (elastic) section modulus of the rail against horizontal loads;

rail
W is the modified section modulus of the post;
mod, post

W is the original (elastic) section modulus of the post against horizontal loads normal to the

post
road.

The equation is applicable for metal, concrete, plastic and wood posts, too, when f is replaced by

a relevant parameter related to short duration loads in temperature of -5 which do not cause

permanent deformation or cracks.
C.4.3 Strength against vertical loads

The evaluation of the connection between the post and rail shall be performed in the following way:

ƒ in case of a simple shear connection with one bolt per connection the bolt dimension and

strength class is simply compared with the bolt characteristics given in Table C.1;

ƒ in other cases of connection a static calculation shall show in class 3 and 4 that the

connection resists the same vertical point load (ULS) as one M 10 4.6 bolt in a simple shear

connection.
C.4.4 Evaluation of gliding conditions

In classes 3 and 4 the evaluation of gliding conditions in any barrier type includes the following:

ƒ identify the contact line in the traffic face of the barrier along which a plough with a vertical

side edge glides;
ƒ does the line protrude at least 40 mm in front of the posts;

ƒ are there any bolts or roughness which may prevent the plough from gliding along that line,

such as:
o a cup head of a bolt shall not protrude more than 12 mm from the contact line;
o a normal hexagonal head of a bolt shall not protrude more than 6 mm from the
contact line;
o a perpendicular step from the contact line shall not exceed 8 mm;
o a tapered (45°) step from the contact line shall not exceed 25 mm.

EN 1317-5:2007+A1:2008/FprA2:2011(E)
C.5 Report

Observed material thickness, section modulus of the rail and post, including their modified values,

and bolt characteristics and calculations and conclusions shall be reported. Calculations are not

necessary if the results are self evident (e.g. M12 4.6. bolt compared with M10 4.6 bolt).

C.6 Innovative barrier types

Barrier types not mentioned above (concrete rail, wooden rail, plastic rail etc.) and innovative

barrier types (rail thickness varies along the length, flexible self-restoring posts, etc.) shall be

evaluated in a field exposure test where the barrier shall be compared along the same road section

with reference barriers, preferable two other barrier types, which are already classified in

accordance with Table C.1. In this road section the snow has to be removed beside the barrier in a

way where a contact between the plough and the rail is common, and snow is removed at least

100 times before the evaluation. The damage in all the barriers shall be reported with photographs

and damage descriptions.

As an alternative, controlled impacts by a snow plough may be used. In the test the barrier shall be

compared with two other barrier types, which are already classified in accordance with Table C.1.

The damage in all these barriers shall be reported with photographs and damage descriptions."
