3 6 6
fulfilled l shall begreater than 0,5 l and less than l + 15 mm measured along a line in the middle of
3 5 5
the stiles.
4.3 Top rung clearance l
The dimension l is the horizontal clearance between the top rung and any obstruction (specifically the
wall) when the ladder is in its position of use.
The dimension l is the horizontal distance between the top rung and the wall when measured with the
ladder in its position of use at any angle between 65° and 75° (see Figure 1). This shall not be less than

bottom of the ladder, see Figure 2.
Figure 2 — Outside width b
5 Requirements
5.1 General requirements
The drawings in this part of EN 131 are examples only and products do not need to correspond.
However, dimensions are binding.
For other requirements EN 131-2:2010+A2:2017, Clause 4 applies.
5.2 Distance between rungs/steps
When the ladder is in its position of use the rungs/steps allowed to stand on shall always be equally
spaced in accordance with EN 131-1:2015, 4.1.
In the position of use the construction shall not allow different distances between the rungs/steps with
a tolerance of ±2 mm in the ascendable part of the ladder and ensure that the rung/step sections that
are not extended shall be stacked at the top of the ladder.
Manufacturer shall take all necessary precautions to prevent these distances been altered without
manipulation and the use of tools.
5.3 Additional requirements for the top of leaning ladders
The top of the ladder shall be designed in a way that a 2-point area of contact between the top of the
ladder and a vertical plane can be ensured.
5.4 Locking of the rung/step sections
The ladder shall be designed in way that all extended rung/step sections are locked when the ladder is
in the position of use.
Every rung/step section shall have a locking mechanism for each stile. With the ladder in position of use
it shall be clearly visible to the user that all of the locking mechanisms are locked or unlocked.
NOTE Visible indication can for example be a coloured area of a visible locking pin.
5.5 Design
Screws and nuts shall be secured against loosening, for example by means of self-locking or
mechanically locked safety mechanisms.
It shall not be possible to separate rung/step sections without using tools.
The unlocking and sliding in of the ladder shall be possible in a safe way. The ladder shall be designed in
a way that squeezing between the rungs/steps is avoided when the ladder is used in accordance to the
user instructions.
Protection against squeezing can be ensured by a breaking function that reduces any impact load on the
user’s hands when the ladder is collapsed according to the manufacturer's instruction. If a permanent
breaking function is used a typical time for collapsing a section of 300 mm is 1,5 s if the movement is
uniform.
If only a distance device is used for protection against squeezing between the rung/steps this device
shall be located at least 80 mm from the manufacturers recommended position of the user’s hands
during collapse of the ladder.
5.6 Base width b
The minimum permanently available base width b for leaning ladders with a length l of 3 000 mm or
2 1
more shall be derived from:
bb=+0,1×l
24 1
Where b is the outside width of the stiles at the bottom of the ladder excluding any rung/step brackets,
see 4.4.
6 Testing
6.1 General
Telescopic ladders shall be tested to and comply with the requirements defined in EN 131-6.
For all tests, unless otherwise stated in the particular test, the following tolerances apply:
— ±1 mm for longitudinal measurements;
— ±5 mm for the measurement of the distance between the supports and the overhanging length;
— ±1 ° for the measurement of angles;
— ±1 % for static forces and torque.
Tests shall be performed at a temperature between 15 °C and 25 °C.
Where the ascendable side cannot be determined by the construction of the product, or where it is a
multiple part combination ladder, the ladder shall be tested twice regarding 6.3 and 6.4. Conduct
strength test and bending test on one side then rotate the ladder 180 ° about the longitudinal axis and
repeat 6.3 and 6.4. The second test can be carried out on a new ladder.
Inspect the ladder before testing to confirm condition and operation of all parts by fully extending the
ladder.
6.2 Ladder preconditioning
6.2.1 General
Ladders for testing shall be preconditioned according to 6.2.2.
After preconditioning the following requirement shall be met:
— no rupturing of parts shall be observed;
— the release function and/or locking indicator shall work correctly;
— the locking mechanism shall work correctly;
— there shall be no relative movement between the connectors and the rungs/steps;
— permanent deformation is only acceptable providing the ladder remains fully functional and it does
not impair the fitness for use, or safety, of the ladder;
— the complete ladder shall be fit for use;
— the protection system against squeezing or entrapment shall be fully functional.
The ladder shall pass all the test from test block A, see Annex A
6.2.2 Drop test
Place the extended ladder in vertical position. Let the ladder fall in the direction of use from vertical to
horizontal position on a flat concrete floor by its own weight. Repeat the test with ladder rotated 180 °
about the longitudinal axis.
Bring the ladder back to storage position.
6.3 Strength test of stiles
The test shall be carried out on the complete ladder. The test shall be carried out on the maximum
extended ladder according to the manufacturer’s instruction.
Where the ascendable side cannot be determined by the construction of the product the ladder shall be
tested twice. For the second test the ladder shall be rotated 180 ° about the longitudinal axis. The
second test can be carried out on a new ladder.
Erect the ladder in its position of use at
