American Society for Testing and Materials (ASTM). Current edition approved Nov. 1, 2009. Published January 2010. Originally approved in 2004. Last previous edition approved in 2004 as A1042/A1042M - 04. 8 p. This specification covers composite corrugated steel pipe, intended for uses such as storm water drainage, sanitary sewers, underdrains, construction of culverts, and similar uses. The composite material used in fabrication of the pipe consists of a three-layer polymer protective coating on both sides of a steel sheet core. The three layers consist of an inner layer of fusion-bonded epoxy on the steel surface, an intermediate layer of polyethylene adhesive, and an outer layer of high-density polyethylene.
