Requirements for materials, details of construction and performance.

This British Standard specifies requirements for materials, details of construction and performance for portable aluminium ladders, steps, trestles and stagings of the following types: single-section ladders, including shelf ladders; extending ladders; standing step ladders, including swing back steps, folding platform steps and ladder backed steps; folding trestles; lightweight stagings; combination ladders. This standard does not apply to ladders for special professional use such as fire brigade ladders, or to mobile ladders which require mechanical aids for erection.
