    Withdrawn Rationale:

    This 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    Formerly under the jurisdiction of Committee C13 on Concrete Pipe, this specification was withdrawn in September 2020 and combined with Specification C478 to become C478/C478M.1

    1. Scope

    1.1 This 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.

    1.2 Part I, Sections 1 – 11, of this specification presents general requirements and requirements which are common to each precast concrete product covered by this specification.

    1.3 Part II of this specification presents specific requirements for each manhole product in the following sections:

     

    Product

    Section

     

     

    Grade Rings

    12

     

     

    Flat Slab Tops

    13

     

     

    Risers and Conical Tops

    14

     

     

    Base Sections

    15

     

     

    Steps and Ladders

    16

     

    Note 1: Future products will be included in Part II in a future revision of this specification.

    1.4 This specification is the SI companion to C478.

    Note 2: This specification is a manufacturing and purchase specification only, and does not include requirements for backfill, or the relationship between field load conditions and the strength requirements of the manhole products and appurtenances. Experience has shown, however, that the successful performance of this product depends upon the proper selection of the product strength, type of foundation and backfill, and care in the field installation of the manhole products and connecting pipes. The owner of the project for which these products are specified herein is cautioned to require inspection at the construction site.

    1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

    1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
