Anotácia textu normy ASTM C655-19a :

This specification covers reinforced concrete pipe, D-load culvert, storm drain, and sewer pipe for the conveyance of sewage, industrial wastes, and storm water. The numerical values in this specification are not presented in inch-pound units, but rather, in metric or SI units only. The reinforced concrete shall consist of cementitious materials, mineral aggregates, and water, in which steel has been embedded in such a manner that the steel and concrete act together. The combination of cementitious materials used in the concrete shall be only one of the following: Portland cement, Portland blast furnace slag cement, slag modified Portland cement, Portland pozzolan cement, a combination of Portland cement and fly ash, a combination of Portland cement and ground granulated blast-furnace slag, or a combination of Portland cement, ground granulated blast furnace slag, and fly ash. Reinforcement shall conform to the standard specification. Physical requirements shall conform to the design strength designation of the pipe during load test. The aggregates shall be sized, graded, proportioned, and mixed with such proportions of cementitious materials and water as will produce a homogeneous concrete mixture of such quality that the pipe shall conform to the test and design requirements of this specification. The strength of the pipe shall not be adversely affected by the splice. Compression tests for determining concrete compressive strength shall be allowed to be made on either concrete cylinders or on cores drilled from the pipe. Pipe shall be repaired, if necessary, because of imperfections in manufacture, damage during handling, or pipe that have been cored for testing.
