Type Cand D tubes are not suitable for safe-ending for forge welding. Tubing having other dimensions may be furnished, provided such tubes comply with all other requirements of this specification. When these products are to be used in applications conforming to ISO Recommendations for Boiler Construction the requirements of A shall supplement and supersede the requirements of this specification. The values stated in either inch-pound units or SI units are to be regarded separately as standard. W within the text, the SI units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system must b used independently of the other.

Historical Version s - view previous versions of standard. More A This specification covers standards for electric-resistance-welded tubes with minimum-wall-thickness made of carbon steel and carbon-manganese steel to be used in boiler tubes, boiler flues, superheater flues, and safe ends.
The steel shall be of Grades A low-carbon steel , C medium-carbon steel , or D carbon-manganese steel. All tubes shall be submitted to heat treatment after welding, followed by cooling. The steel shall conform to stated compositions of carbon, manganese, phosphorus, sulphur, and silicon. Grades C and D shall conform to given tensile requirements, that is tensile strength, yield strength, and elongation.
The material shall also be subjected to flattening, flange, tension, reverse flattening, and hydrostatic or nondestructive electric tests. Crush test shall also be performed if asked by the purchaser. Minimum elongation values are also given.
