1. Definitions  
For the purposes of this Annex, the following definitions apply:  
(1) “soft shell box body” means a box shaped  body work  where at least the two sides of 
the body are covered by tarpaulin entirely or between the upper edge of the hinged 
side panels and the roof of the superstructure, and for which the digits used to 
supplement t he codes of bodywork are 32, or 06.  
(2) “hard shell box body” means a box shaped body work  for which the digits used to 
supplement the codes of bodywork are 03 or 05.  
(3) “refrigerated box body” means a box shaped  body work  for which the digits used to 
supplement th e codes of bodywork are 04.  
(4) ‘internal height of the body’ means the internal height of the body dimension without 
taking into account internal projections ( including wheel  boxes, ribs  and hooks) as 
defined in point 6.15 of Standard ISO 612:1978. If the roof is curved, the dimension 
shall be  measured between the planes (vertical or horizontal, depending on the case) 
tangential to the apices of the curved surface, the dimension being measure d inside 
the body.  
(5) ‘internal length of the body’ means the internal length of the body dimension without 
taking into account internal projections ( including wheelboxes, ribs  and hooks) as 
defined in point 6.15 of Standard ISO 612:1978. If the front or rear  wall is curved, 
the dimension shall be  measured between the vertical planes tangential to the apices 
of the curved surface(s), the dimension being measured inside the body.  
(6) ‘volume orientation" means that the trailer is primarily designed for the transpor t of 
voluminous goods and has an internal height of not less than 2.9 meters : 
(a) in the case of semi -trailers, measured from the landing gear to the end of the 
loading area ; 
(b) in the case of drawbar trailers, and centre -axle trailers, measured along the 
entire length of the loading area.

DETERMINATION OF AERODYNAMIC DEVICE DATA  
1. Introducti on 
This Annex sets out the procedure for the determination of the aerodynamic device data.  
2. Definitions  
(1) Standard aerodynamic devices are aerodynamic devices for which standard values can 
be used in the vehicle certification . The standard aerodynamic device may consist the 
following elements:  
(a) ‘rear flaps’ means an aerodynamic device composed by two or more rear fairing 
panels located at the rear end of the vehicle with the aim to reduce its wake;  
(b) ‘short rear flaps’ means a rear flaps which lateral panels meas ure at least 2 meters 
and do not cover the total height of the body;  
(c) ‘tall rear flaps’ means a rear flaps which lateral panels cover the entire height of 
the body;  
(d) ‘side covers’ means an aerodynamic device composed by panels located at the 
lower side of th e vehicle with the aim to reduce the impact of crosswind and/or the 
turbulences created by the wheels on the air drag;  
(e) ‘short side covers’ means side covers that do not cover the area of the wheels; in 
case of semi -trailers, they cover only the distance be tween the landing gear and the 
beginning of the first wheel;  
(f) ‘long side covers’ means side covers that cover a distance between the landing 
gear of a semi -trailer and the rear end of the vehicle;  
(2)  ‘CFD’ means computational fluid dynamic simulation used for  analysing complex fluid 
phenomena;  
3. Determination of air drag reduction by means of virtual tests using CFD  
3.1. Validation of the CFD method  
Based on the validation process as specified in Annex VIII, Appendix 3 to Regulation 
(EU) 2018/858, the certification o f an aerodynamic device by means of CFD shall 
require the CFD method to be validated against a reference CFD method as shown in 
Figure 1.  
The CFD method to be validated shall be applied to a set of generic geometries.  EN 26  EN  
Figure 1. Validation process of the CFD method  
Comparability of the computer simulation  results shall be proven. The manufacturer of 
the aerodynamic device or the technical service shall draft a validation report and submit 
it to the approval authority.  
Any change to the CFD method or to the software that is likely to invalidate the 
validation report shall be brought to the attention of the approval authority, which may 
require that a new validation process is conducted.  
Once validated, the model shall be used for c ertifying the aerodynamic device.  
3.2. Requirements for the validation of the CFD method  
The validation process shall consist of simulating three different CFD simulation sets as 
follows:  
(a) BASE set:

– Generic ST1 semi -trailer  
– Generic tall rear flaps 
(c) LSC set:  
– Generic 4x2 tractor  
– Generic ST1 semi -trailer  
EN 27  EN – Generic long side covers  
 
Each set shall be simulated at β=0.0, 3.0 and 6.0 degrees of yaw to account for 
crosswind effects coming from the l eft hand side of the vehicle, as shown in Figure 2.  
 
Figure 2: β yaw angle  
 The heat exchangers pressure drop shall be modelled as per equation [1]:  
 
𝑑𝑝
𝑑𝑥=−(𝑃𝑖·𝑣2+𝑃𝑣·𝑣)    [1] 
 
where the coefficients for each heat exchanger shall be as listed i n Table 5.

Family concept  
1. General  
An aerodynamic device family is characterised by design and performance 
parameters. Th ose parameters  shall be common to all members within the family. 
The manufacturer  of the aerodynamic devices  may decide which aerodynamic 
devices belong to a family, as long as the criteria listed in point 4 of this Appendix 
are respected. The Approval Auth ority  shall approve aerodynamic device  family. 
The manufacturer  of the aerodynamic devices  shall provide the Approval Authority 
with the appropriate information about  the members of the family.  
2. Special cases  
2.1. In some cases there may be interaction between p arameters. Th e manufacturer  of the 
aerodynamic devices shall identify those cases and take them into consideration  to 
ensure that only aerodynamic devices with similar characteristics are included within 
the same family. The manufacturer  of the aerodynamic  devices  shall notify th ose 
cases to the  approval authority to take them into account as a criterion for creating a 
new aerodynamic device family.  
2.2. The manufacturer shall identify  parameters  which are not listed in point  3 and which 
have a strong influence on the level of performance on the basis of good engineering 
practice and notify those parameters  to the approval authority.
