4.1 The dimensions for ladders are given in EN 131-1. The ladder shall meet the dimensional

requirements for ladders given in EN 131-1.
4.2 The maximum platform height h shall be 1 000 mm.
4.3 The maximum usable platform length shall be 1 250 mm.

NOTE The maximum platform length is specified in order to reduce the possibility of overloading.

4.4 The minimum platform useable surface width at any point shall be 310 mm.
5 Design and test requirements
5.1 General
The design requirements are based on a maximum total load of 150 kg.
The product shall meet the test requirements of Clause 6.
5.2 Ladder

5.3.4 Metal parts susceptible to corrosion shall be protected by means of a paint coating or other

coating. Under normal conditions aluminium alloys are not susceptible to corrosion. Wooden parts shall

be coated on all sides. The coating shall be transparent and permeable to water vapour.

5.3.5 In order to avoid injuries, accessible edges, corners, and protruding parts shall be free of burrs,

for example chamfered or rounded. Wooden parts shall be smoothed on all sides.

5.3.6 All connections should be durable and have a strength corresponding to the strain.

5.3.7 If the product has a crossbar it shall meet the requirements of 6.9, test for crossbar.

5.3.8 Connections should be designed in a manner that arising notch tensions remain low. Screws and

nuts shall be secured against unintentional loosening, e.g. by means of self-locking or mechanically

locked safety devices.

Nails are allowed only if their function is related to the production process, e.g. fixation during the

drying of glues.

5.3.9 The platform shall have slip resistant upper surface. The contact surface of any coverings which

provide the slip resistant surface shall adhere firmly to the platform.

5.3.10 The platform and ladders shall be designed so that it is not possible to position the platform

with its upper surface more than 1 000 mm from the ground on both ladders (see Figure 4). A marking

is not sufficient to limit the maximum platform height.
