A new European standard for ladders according to the latest EN 131 series standards
PN EN 131 2+A2:2017
New significant changes will come into effect on 1 January 2018 for all ladders that can be used as a leaning ladders, and whose length exceeds 3 meters. The new regulations of the EN 131-1 standard, in a substantial part, refer to the obligation of equipping these devices with a stabilizer, which increases the width of the ladder support, and thus the safety of users. The modified EN 131-2 standard also imposes on the manufacturers a number of new ladder strength guidelines and introduces a new division of ladders in terms of the user group.
All products are divided into two classes:
For ladders with a height of more than 3000 mm, which can be used as a leaning ladder, the new standard requires widening the ladder base to a maximum of 1200 mm, depending on the length of the ladder.
The step / rung in the position of use, is loaded with an eccentric test force:
- about 270 kg for "Professional" class ladders,
- around 225 kg for "Non-professional" class ladders.
• The ladder must not be damaged, the function must be ensured.
• The ladder's foot is clamped.
• The ladder platform is loaded with a force of approx. 74 kg.
• Then the ladder is stretched from the side with a force of approx. 13.7 kg.
• During loading, the second ladder’s foot may move away from its current position up to 25 mm.
Variable loading of the highest step or rung and middle step or rung ladder with a force of approx. 150 kg.
• There must be no damage
• The ladder is standing on a glass plate.
• The ladder is loaded in the middle with a force of approx. 147 kg.
• The loading is repeated 4 times.
• Ladder feet can move up to 40 mm in 1 minute.
• One of the ladder stiles is loaded in the center with a force of approx 64 kg, after which the deformation of both stringers is measured to a predetermined starting value.
The difference between the deformation of both arms can be up to 0.07 the width of the ladder.
