New ladders are generally marked according to their safe working load. This classification however, can vary slightly in the values given, and has caused confusion.
The variation is due to the different way in which the values for safe working are expressed. In the British Standard it is "Duty rating". These have been arrived at by taking into account the general conditions and probable frequency of use for each type.
The European Standard uses "Maximum static vertical load". To help clarify this, we have given both sets of figures. British Standard stepladders to BS 2037 (Aluminum) or BS 1129 (Wood) or BS 7377(Step-stools).
· Class 1 (Industrial) - Heavy Industrial Use Duty rating 130kg - Maximum vertical static load 175kg.
· BS/EN 131 (Previous Class 2) - Light Trade Use Duty rating 115kg - Maximum vertical staticload 150kg.
· Class 3 (Domestic) - Domestic DIY Use Duty rating 95kg - Maximum vertical static load 125kg.

It is important that you choose the ladders that best fit your needs. If you are a builder or tradesman buying a Class 3 ladder is not advisable as they are not designed to withstand the rigors of day to day trade use.
Even if you are looking for home use ladders you may want to think about buying a set that at least meet the EN 131 standard. They will be safer, last longer and probably work out more economical over the longer term
