Basic Information
Scope
This standard specifies the classification, raw materials, requirements, test methods, inspection rules, marking, packaging, transportation, storage, and product factory certificates of concrete and reinforced concrete drainage pipes.
This standard applies to concrete and reinforced concrete drainage pipes formed by centrifugal casting, suspension roll casting, core-mold vibration, vertical extrusion, and other methods.
This standard applies to pipes for gravity flow pipelines such as rainwater, sewage, water diversion, and farmland irrigation. For concrete and reinforced concrete drainage pipes used for other purposes (such as requiring special anti-corrosion), the parties concerned may refer to this standard for implementation through consultation.
Pipes produced in accordance with this standard are suitable for trench construction, pipe jacking, and other construction methods.
