Foreword
This document (EN 926-1:2006) has been prepared by Technical Committee CEN/TC 136 “Sports,
playground and recreationnal 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text or by endorsement, at the latest by February 2007, and conflicting national standards shall be withdrawn
at the latest by February 2007.
This document supersedes EN 926-1:1995.
This standard is one of a series of standards on equipment for paragliding as follows:
EN 926-1, Paragliding equipment — Paragliders — Part 1: Requirements and test methods for structural
strength
EN 926-2, Paragliding equipment — Paragliders — Part 2: Requirements and test methods for classifying
flight safety characteristics
EN 1651, Paragliding equipment — Harnesses — Safety requirements and strength tests
EN 12491, Paragliding equipment — Emergency parachutes — Safety requirements and test methods
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following
countries are bound to implement this European Standard: Austria, Belgium, Cyprus, Czech Republic,
Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania,
Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden,
Switzerland and United Kingdom.
Introduction
EN 926-1 and EN 926-2 are intended to provide a method of qualifying paragliders.
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 either been obtained by using a uniform scale factor, or by adding/removing
cells in the centre of the canopy;
b) any cells inserted in the centre of bigger sizes are technically identical to adjacent cells;
c) on scaled paragliders the architecture of the structure of the suspension line system is identical. The
lengths of the suspension lines are either identical for all sizes, or have been scaled up/down by a factor
not greater than the scale factor of the canopy;
d) for all sizes identical materials are used;
e) the way materials are processed is identical for all sizes.
2.3
identically constructed lines
lines which are considered to be identically constructed if the only elements that alter are finished line length and
cosmetic colour
3 Requirements
3.1 Shock loading
When tested according to 4.4 the wing shall not be damaged.
3.2 Sustained loading
When tested according to 4.5 the wing shall not be damaged.
3.3 Breaking strength of the lines
The lines shall be tested according to 4.6. If identically constructed lines have already been tested, then the
result may be used.
For A- and B-lines in the lowest section (i.e. next to the risers) the sum of
F 1 × n1 + F 2 × n 2 + F 3 × n 3 + .
break break break
where
F 1, 2, 3,. is the breaking load line type 1, 2, 3,… used in the lowest section of the A- and/or B-
break
lines);
n 1, 2, 3,. is the number of lines of line type 1, 2, 3,… used in the lowest section of the A- and B-
lines
shall exceed the greater of 8 × g × [max weight in flight] or 8 000 N (g = 9,81 m/s ).
For each of the other line sections above, the same calculation is performed. The result shall exceed the
result obtained for the lowest section.
For the C- and D-lines (and any further suspension lines) in the lowest section the sum of
F 1 × n 1 + F 2 × n 2 + F 3 × n 3 + .
break break break
where
F 1, 2, 3,…is the breaking load line type 1, 2, 3,. used in the lowest section of the C- and/or D-
break
lines (and/or any further lines);
n 1, 2, 3,.is the number of lines of line type 1, 2, 3,. used in the lowest section of the C-, D-, or any
further lines
shall exceed the greater of 6 × g × [max weight in flight] or 6 000 N.
For each of the other line sections above, the same calculation shall be performed. The result shall exceed
the result obtained for the lowest section.
4 Test methods
4.1 Apparatus
4.1.1 Weak link
The weak link shall be calibrated 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, in kg < 120 120 to 180 180 to 240 ≥ 240
Break load of the weak link, in daN 800 1 000 1 200 1 400
For each additional 60 kg value above 240 kg total weight in flight, the break load of the weak link shall be
increased by 200 daN.
4.1.2 Cable
A steel cable of 150 m in length, of minimum specification of 6 mm diameter, 18 × 7 all steel construction,
tensile grade 1 600 N/mm , may be covered with non-metallic protective coat.
4.1.3 Electronic sensor
An electronic sensor equipped with an electronic strain gauge for measuring the force (sampling a minimum of 5 times per
second).
4.1.4 Measurement circuit
With a graph clearly showing the load (N) against time (s).
4.1.5 Video recording equipment
To be mounted on the test vehicle.
4.2 Test specimen
Select a test specimen that conforms to the manufacturing record for that model (see Annex A).
Either every size of a particular paraglider design shall separately be tested or where different sizes meet the
criteria of being the same model, then it is sufficient that the size with the largest maximum total weight in
flight is tested.
In this case:
a) if smaller/bigger versions of the test
