BS EN 131-2:2010 pdf download.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.
It does not apply to ladders used for work on or near live electrical systems or installations. For this purpose EN 61478 applies.
NOTE For insulating ladders for use on or near low voltage electrical installations in the range below 1000 V a-c or 1 500 V d.c. EN 50528 is under preparation.
This European Standard is intended to be used in conjunction with EN 131-1, For single or multiple hinge joint ladders EN 131-4 applies.

3 Terms and definitions
For the purposes of this document, the terms and definitions given in EN 131-1:2007 and the following apply.
3.1 thermoset plastic
plastic that has been cured by heat or by other means such as radiation, catalysts, etc., into a substantially infusible and insoluble state
[EN ISO 472:2001]
3.2 composite material
crosslinkable resin-based material with a continuous reinforcement fibre as filler (e.g. fibreglass)
3.3 thermoplastic material
plastic material other than thermoset plastic or composite with or without filler and with or without reinforcement
3.4 maximal total load
maximum weight that the ladder is designed to support when set up in accordance with the manufacturers instruction
4.1 General
The requirements are based upon a maximum total load of 150 kg.
Ladders are determined to be used by one person at a time but this exdudes any person footing (stabilising) the
ladder.
4.2 Materials
4.2.1 Aluminium — alloy
All load bearing parts made of aluminium alloy shall have an elongation A5 at rupture measured according to
EN ISO 6892-1 of minimum 5 %.
All load bearing parts made of aluminium alloy shall have a thickness of at least 1.2 mm.
4.2.2 Steel
If cold rolled steel or a special alloy-steel is used the ratio between 0,2 % yield-stress and ultimate strength (Rr 0,2/Rm) shall be lower than 0.92.
All load bearing parts made of steel shall have a thickness of at least 1,0mm.
4.2.3 Plastics
Glass-fibre reinforced plastics shall be protected against penetration of water and dirt. The surface shall be smooth, The fibres shall be embedded. The Barcol hardness according to EN 59 shall be at least 35.
The test methods and acceptance criteria for defining the characteristics of the composite and reinforced thermoplastic materials are given in 5.16. They apply to the load-bearing elements (stiles, climbing supports, platforms) of the structure of ladders at time of use. Thermoplastic materials without reinforcements shall not be used for load bearing-elements.
The minimum thickness for load-bearing elements made of thermoset plastics and composite material is 2 mm. When using plastics materials, ageing and temperature resistance shall be taken into account.BS EN 131-2 pdf download.
