European foreword
This document (EN 926-1:2015) has been prepared by Technical Committee CEN/TC 136 “Sports,
playground and recreational equipment”, the secretariat of which is held by DIN.
This European Standard shall be given the status of a national standard, either by publication of an
identical text or by endorsement, at the latest by May 2016, and conflicting national standards shall be
withdrawn at the latest by May 2016.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent
rights.
This document supersedes EN 926-1:2006.
In comparison with the previous edition, the following significant changes have been made:
a) editorial revision;
b) revision of line strength calculation method;

Introduction
The EN 926 series consists of two parts: EN 926-1 details paraglider structural strength requirements
and EN 926-2 details paraglider flight tests requirements. Paragliders that have been tested and found
to be compliant with both EN 926-1 and EN 926-2 are therefore compliant with the EN 926 series.
The aim of these standards is to enhance safety thus eliminating paragliders which display
unacceptable behaviour in given situations on the basis of recognized tests set in these two standards.
1 Scope
This European Standard is applicable to paragliders as defined in 2.1.
This part of EN 926 specifies requirements and test methods for the resistance of a paraglider to static
and dynamic loads and sets the minimum strength threshold for its qualification.
2 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
2.1
paraglider
ultra-light glider with no primary rigid structure, for which take-off and landing are on foot, with the
pilot (and potentially one passenger) carried in a harness (or harnesses) connected to the wing
2.2
model of paraglider
paragliders of different sizes of a given design are considered to be the same model when fulfilling the
following criteria:
a) the different sizes have been obtained by using a uniform scale factor;
b) for all sizes identical materials are used;
c) the way materials are processed is identical for all sizes
2.3
identically constructed lines
lines where the only elements that differ are the finished line length and/or cosmetic colour
2.4
main control lines
entire line systems that terminate at the two primary control handles
2.5
significant damage
rupture of any of main load bearing component of the structure
3 Requirements
3.1 Shock loading
When tested according to 4.4, a visual inspection of the wing shall not show significant damage.
3.2 Sustained loading
When tested according to 4.5 the wing shall sustain 4.5.2. 1) or 4.5.2 2).
3.3 Breaking strength of the suspension lines
The lines shall be tested according to 4.6. If identically constructed lines have already been tested, then
the result may be used.
The minimum breaking strength of any line shall be greater than 200 N. The first level is defined as the
lines attached to the risers.
The sum of strength after bending test of the lines of the first level shall exceed the greater of
14 × g × [max weight in flight] or 14 000 N (g = 9,81 m/s ).
For each level the same calculation is performed. The result shall exceed the greater of
14 × g × [max weight in flight] or 14 000 N (g = 9,81 m/s ).
Subsequent levels (as shown in Figure 1) are defined by each further line junction. If a line is directly
attached to the wing (i.e. no line junction above it), its strength shall also be used during the calculation
of the strength of each of the level(s) above it. An example calculation is given in Annex A.

3.4 Breaking strength of the main control lines
The lines shall be tested according to 4.6. If identically constructed lines have already been tested, then
the result may be used.
The sum of the strength of the lines of each level shall exceed 1 500 N (i.e. 2 × 750 N).
The minimum breaking strength of any line shall be greater than 200 N.
The first level is defined as the lines attached to the main control handle(s) including the control handle
and the attachment of the line to the handle.
When a control handle is connected to a control line in the manner described in the user manual, the
connection between the control handle and the first level of line shall have a minimum breaking
strength of 750 N.
4 Test methods
4.1 Apparatus
4.1.1 Weak link
The weak link shall be chosen for instantaneous break at a load defined in Table 1 according to the total
weight in flight:
Table 1 — Selection of weak link break loads
Total weight in flight < 120 120 to 180 180 to 240 ≥ 240
(kg)
Break load of the weak link 8 000 10 000 12 000 14 000
(N)
The use of weak links with a tolerance of ± 5% is allowed. Weak links shall be protected against
torsional load as recommended by the manufacturer.
For each additional 60 kg value above 240 kg total weight in flight, the break load of the weak link shall
be increased by 2 000 N.
Where individual weak links of the specified values are not available, it is permissible to pair in parallel
two identical weak links of half of the required value.
4.1.2 Cable
The shock test cable shall meet the following requirements:
— length: 125 m (±1%);
— minimum breaking strength: ≥ 50 kN;
— the elastic elongation at 5 kN shall be between 11,8 cm and 14,4 cm.
NOTE The elastic elongation is equal to 1,05 per thousand (± 10 %) at 5 kN .
4.1.3 Electronic sensor
An electronic sensor equipped with an electronic strain gauge for measuring the force (sampling a
minimum of 10 times per second) is required for 4.5.
4.1.4 Measurement circuit
With a graph clearly showing the load (N) against time (s).
4.1.5 Video recording equipment
Video recording equipment shall be used to record the overall behaviour of the glider during the tests.
More than one camera may be used. .
4.1.6 Test vehicle
For the shock load test, a vehicle with a verified means of indicating ground speed to within ± 1 km/h,
shall be used.
4.2 Test specimen
Select one test specimen that conforms to th
