American Society for Testing and Materials (ASTM). Current edition approved March 1, 2007. Published April 2007. Originally approved in 2000. Last previous edition approved in 2002 as A 1012-02. 4 p. This specification describes seamless and welded ferritic, austenitic and duplex alloy steel tubing on which the external or internal surface, or both, has been modified by a cold forming process to produce an integral enhanced surface for improved heat transfer. The tubes are used in surface condensers, evaporators, heat exchangers and similar heat transfer apparatus in unfinned end diameters up to and including 1 in. (25.4 mm). Boiler tubes are excluded.
