have to be taken in order to achieve the following performances where they form part of the pedestrian
parapet:
a) a continuous flowing alignment;
b) smooth surfaces;
c) the absence of sharp edges that could cause injury to users;
d) the provision for expansion, contraction and movement of the main structure (e.g. under traffic loads and
temperature effects) so that these do not endanger the performance or flowing alignment;
e) the avoidance of corrosion pockets;
f) the provision for adequate drainage in hollow sections and channels;
g) the compatibility between component parts so that there is avoidance of electrolytic action;
h) that fixings and fittings cannot be loosened without using tools;
i) to demonstrate the ease of assembly at site location, the ease of maintenance and repair including the
replacement of parts;
j) finish and surface protection;
k) any special provisions for end posts/panels.
NOTE A method for ensuring a smooth finish is described in Annex G.
4.2.2 Optional facilities

4.3 Geometrical requirements
4.3.1 Height of manufactured product
The height H of the manufactured pedestrian parapet should be declared. Where the pedestrian parapet is to
p
be installed at an angle, the vertical height H should be declaredm see Figure 1.
p
NOTE The overall height HO of the pedestrian parapet is related to Hp but depends on the location of the fixing. See
Figure 1 for examples. Where the post height exceeds the height of the top horizontal rail the declared height should be to
the top of the top rail.

Height should be measured with equipment that accords EN ISO 9001.
4.3.2 Spaces and voids
The spaces and voids should not allow the passage of a spherical object with a diameter D . The maximum
b
value of D should be declared as D . Various values for D should be declared in relation to height, see
b s s
Figure 2.
Determination of D should take account of manufacturing tolerances and measured from a sample (using

NOTE The selection of void size(s) may have implications for
i) the avoidance of footholds which could make provision for persons to climb the pedestrian parapet (e.g.
minimum height 1,1 m and no horizontal ledges on traffic face greater than 15 mm);
ii) visibility (transparency/intervisibility) for drivers particularly at road junctions where there is a need for side
visibility (e.g. percentage of clear view area through parapet when viewed at a specified angle);
iii) the avoidance of objects being thrown through the pedestrian parapet onto traffic below (e.g. limiting a
void/space size to 5 mm).
The above implications are mainly related to the site location of the pedestrian parapet which is not an issue
for this Technical Report and further guidance on the selection of sizes may be found in guideline
requirements prepared by Member States.

have to be taken in order to achieve the following performances where they form part of the pedestrian
parapet:
a) a continuous flowing alignment;
b) smooth surfaces;
c) the absence of sharp edges that could cause injury to users;

temperature effects) so that these do not endanger the performance or flowing alignment;
e) the avoidance of corrosion pockets;
f) the provision for adequate drainage in hollow sections and channels;
g) the compatibility between component parts so that there is avoidance of electrolytic action;
h) that fixings and fittings cannot be loosened without using tools;
i) to demonstrate the ease of assembly at site location, the ease of maintenance and repair including the
replacement of parts;
j) finish and surface protection;
k) any special provisions for end posts / panels.
NOTE A method for ensuring a smooth finish is described in Annex G.

4.3 Geometrical requirements
4.3.1 Height of manufactured product
The height H of the manufactured pedestrian parapet should be declared. Where the pedestrian parapet is to
p
be installed at an angle, the vertical height H should be declared see Figure 1.
p
NOTE The overall height H of the pedestrian parapet is related to H but depends on the location of the fixing. See
O p
Figure 1 for examples. Where the post height exceeds the height of the top horizontal rail the declared height should be to the top of
the top rail.

Height should be measured with equipment that accords EN ISO 9001.
4.3.2 Spaces and voids
The spaces and voids should not allow the passage of a spherical object with a diameter D . The maximum
b
value of D should be declared as D . Various values for D should be declared in relation to height, see
b s s
Figure 2.
Determination of D should take account of manufacturing tolerances and measured from a sample (using
s
callipers) and/or an analysis of the manufacturing drawings.

NOTE The selection of void size(s) may have implications for
i) the avoidance of footholds which could make provision for persons to climb the pedestrian parapet (e.g. minimum
height 1,1 m and no horizontal ledges on traffic face greater than 15 mm);
ii) visibility (transparency / intervisibility) for drivers particularly at road junctions where there is a need for side visibility
(e.g. percentage of clear view area through parapet when viewed at a specified angle);
iii) the avoidance of objects being thrown through the pedestrian parapet onto traffic below (e.g. limiting a void / space
size to 5 mm).
The above implications are mainly related to the site location of the pedestrian parapet which is not an issue for this
Technical Report and further guidance on the selection of sizes may be found in guideline requirements prepared by
Member States.

4.4 Design requirements
4.4.1 General
The design working life under given use and maintenance conditions should be declared.
NOTE A minimum design working life of 25 years is normally required, excluding the possibility of accidental action
(see EN 1990:2002, 2.3).
Pedestrian parapets should be designed in accordance with the general requirements in EN 1990:2002 and
EN 1991 and the material resistance requirements in EN 1992, EN 1993, EN 1994, EN 1995, EN 1996 and
EN 1999 (see subclauses below) for the following limit states:
a) Ultimate Limit State (ULS) (see 4.5.2);
