1.1This specification2 covers four grades of carbon steel forgings for boilers, pressure vessels, and associated equipment.
Note 1:Designations have been changed as follows:
| Current | Formerly |
| Grade 1 | Class 1 |
| Grade 2 | Class 2 |
| Grade 3 | Class 3 |
| Grade 4 | Class 4 |
1.2Supplementary requirements are provided for use when additional testing or inspection is desired. These shall apply only when specified individually by the purchaser in the order.
1.3The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.
1.4Unless the order specifies the applicable “M” specification designation, the material shall be furnished to the inch-pound units.
1.5This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
