Ladders - Part 2: Requirements, testing, marking
This European standard specifies the general design features, requirements and test methods for portable ladders. It does not apply to step stools or ladders for specific professional use such as firebrigade ladders, roof ladders and mobile ladders. This European standard is intended to be used in conjunction with EN 131-1.

amendment into the relevant national standard without any alteration.
This draft amendment was established by CEN in three official versions (English, French, German). A version in any other language made
by translation under the responsibility of a CEN member into its own language and notified to the CEN-CENELEC Management Centre has

1 Modification of Foreword
Delete:
"On stability tests and ladder classes no consensus could be reached. These issues will be addressed in the
next revision”.
Replace with:
“On ladder classes no consensus could be reached and a new test for torsion on ladder length for standing
ladders is required. These issues will be addressed in the next revision.
A test protocol for durability of standing ladders is under preparation as a CEN Technical Specification.
A test protocol for an alternative base slip test is under preparation as a CEN Technical Specification.
2 Modification of Clause 2 Normative reference
Add:
"EN 572-2:2012, Glass in building — Basic soda lime silicate glass products — Float glass”
3 Modification of 4.1 General
Replace with:
"The requirements are based upon a maximum total load of 150 kg. This figure takes account of the weights
of European professionals working at height and their equipment. Ladders are determined to be used by one
person at a time but this excludes any person footing (stabilising) the ladder”.
4 Modification of 4.9 Antiskid devices
Replace title with:
"Ladder feet and anti-skid devices”.
Delete:
“The ends of wood stiles are considered to be slip resistant.”
Add:
NOTE "A test for the base slip resistance of leaning ladders is contained in 5.17.”
5 Modification of 5.2 Strength test of stiles

“Strength test for ladders”

“The test shall be carried out on the complete ladder. In the case of extending ladders and combination
ladders the test shall be carried out on the complete extended ladder. Sectional ladders shall be tested at full
length with all permitted pieces. The test shall be carried out without supporting legs if not permanently fixed
to the ladder. 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. For the second test the ladder shall be
rotated 180° about the longitudinal axis.
The ladder shall be placed horizontally on supports situated 200 mm from each end of the ladder.
The supports shall be cylindrical with diameters between 25 mm and 100 mm and one shall be free to rotate
the other shall be fixed.
The test load (F in Figure 10) of 1324 N shall be slowly applied in the middle of the ladder equally to both
stiles over a width of 100 mm for a period of 1 min. Care should be taken to apply the load smoothly.
After removal of the test load the ladder shall remain functional with no deformation or visible signs of collapse
or fracture.

5.2 – Add NOTE:
NOTE Strength testing of ladders in the horizontal position is preferable to testing in the position of use because
a) of the long experience of testing in this way without evidence of ladder collapse due to insufficient strength
b) the testing is more controllable when carried out horizontally
c) the maximum bending moment is at the centre of the ladder
d) taking into account the effect of second order analysis in the horizontal position it is possible to represent
closely the as used position
e) the maximum stress can be created by loading centrally in the horizontal position.
Asymmetric and dynamic effects are accommodated in the test load.

6 Modification of 5.15 Torsion on ladder length
Replace the 1st paragraph:
"The test unit shall consist of a ladder base section of any length, supported over a 2 000 mm test span
except that if the ladder base section (ascendable part of the ladder) is less than 2 000 mm then the maximum
possible test span shall be used. Place the ladder in a flat horizontal position and support it at each end, as
shown in Figure 28, with the bottom rung directly above the pivotal support."
with
"The test unit shall consist of a ladder base section (section starting from the lower end of the ladder) of any
length, supported over a 2 000 mm test span except that if the ladder base section (ascendable part of the
ladder) is less than 2 000 mm then the maximum possible test span shall be used. Place the ladder in a flat
horizontal position and support it at each end, as shown in Figure 28 with the bottom rung directly above the
pivotal support.
In case of hinged combination ladder with extending part the ladder should be tested with inner side extended
but in position of use."
Replace the 3rd paragraph:
"The angle of twist shall not exceed the value determined by the following equation:"
with
"Each one of the two angles of twist shall not exceed the value determined by the following equation:"
7 Add 5.17 Base slip test for leaning ladders
5.17.1 Ladders to be tested
All leaning ladders or ladders that may be used as a leaning ladder
In the case of single part leaning ladders 4m or less in length then the whole ladder shall be tested.
In the case of single part leaning ladders greater than 4m in length, a 4m length from the lower end of the
ladder shall be tested.
In the case of multi-part sectional or extending leaning ladders where the fully assembled length or fully
extended length is less than 4m then the whole ladder is tested in the fully assembled or fully extended
condition.
In the case of multi-part sectional ladders where the fully assembled length is greater than 4m then a part or
an assembly of parts shall be tested with a length closest to a maximum of 4m.
In the case of extending leaning ladders where the fully extended length is greater than 4m then the ladder
shall be extended to a len
