ASTM A716-18(2022)

Anotace textu normy ASTM A716-18(2022) :

This specification covers ductile-iron culvert pipe centrifugally cast. The pipe shall be manufactured of ductile iron that meets the mechanical requirements such as tensile strength, yield strength, elongation, and impact value. The pipe shall be provided with suitable joints, such as push-on or other types of joints that prevent lateral displacement, but plain-end pipe for use with suitable couplings may be furnished. Standard wall thickness and weight values of push-on joint pipe are given. Pressure Class ductile iron pipe in Type 5 trench is illustrated. All pipe shall be coated inside and outside with an asphaltic material. Acceptance tests by tension and Charpy impact testing shall be performed. The standard test specimens for these testing methods are detailed.
