ASTM International Standard Specification for Vitrified Clay Pipe, Extra Strength, Standard Strength, and Perforated ASTM C700-11

This specification covers extra strength and standard strength vitrified clay pipe and fittings to be used for the conveyance of sewage, industrial wastes, and storm water; and extra strength perforated and standard strength perforated vitrified clay pipe to be used for underdrainage, filter fields, leaching fields, and similar subdrainage installations. Vitrified clay pipe shall be manufactured from fire clay, shale, surface clay, or a combination of these materials that, when formed into pipe and fired to suitable temperatures. Pipe shall meet the bearing strength requirements prescribed. The manufacturer shall at his option, apply either a hydrostatic pressure test or an absorption test to all of the test specimens in each size and run of the pipe. The absorption of vitrified clay pipe shall not exceed 8%. The acid resistance test is used to determine the resistance of pipe to the action of acids encountered in sanitary sewers.
