This standard specifies general requirements and testing methods for steps manufactured from cast iron, steel or aluminium, for use in manholes and other underground man entry chambers as a means of access.
This standard specifies performance criteria for mechanical stability and resistance providing protection against falling. Corresponding test methods and evaluation of conformity are included.
The steps specified in this European Standard are suitable for use in sewage, surface water and, subject to the requirements of national regulations, potable water environments.
Where steps are to be used in particular corrosive environments, e.g. industrial effluents, additional protection may be required.
This standard does not apply for steps moulded in prefabricated manholes of the same material.
