Описание
Причина отменыThis specification covers the manufacture and purchase requirements of products used for the assembly and construction of circular vertical precast reinforced concrete manholes and structures used in sewer, drainage, and water works.
Formerly under the jurisdiction of Committee C13 on Concrete Pipe, this specification was withdrawn in September 2020 and combined with Specification C478 to become C478/C478M.1
