Anotace

This specification covers ductile iron gravity sewer pipe centrifugally cast with push-on joints. This also covers trench load design procedures for both cement-lined pipe and flexible-lined pipe. Maximum depths of cover tables are included for both types of linings. Each pipe shall be subjected to a hydrostatic test and maybe performed either before or after the outside coating and inside coating have been applied, but shall be performed before the application of cement-mortar lining or of a special lining. The standard acceptance tests and additional control tests shall also be performed.
