This specification covers requirements relating to non-asbestos fiber-cement non-pressure sewer pipe, joints, and fittings suitable for use with gravity flow, intended for sewerage and drainage applications from point of use to point of treatment or disposal. The types of pipe shall be shown as type I and type II corresponding to the chemical requirements. Fiber-cement sewer pipe furnished under this specification shall be designated as class I, II, III, IV, and V. The corresponding strength requirements are prescribed. The pipe shall be of laminar construction formed under pressure to a homogeneous structure and cured under natural or accelerated conditions to meet the chemical and physical requirements. Crushing tests, and longitudinal bending tests shall be conducted to meet the requirements prescribed. A hydrostatic pressure test shall be made on an assembly of two sections of pipe properly connected with a coupling to meet the requirements prescribed.
