This document specifies a method of testing the resistance of the upper assembly of inspection chambers and manhole components against surface and traffic loading.
It is not applicable to requirements for testing the cover and frame. Those requirements are specified in EN?124-1 or other standards, depending on the material.
NOTE?Upper assembly components normally include shafts or risers, cones, telescopic adapters and near surface components.
