Additional information
| 1. Scope |
|
1.1 This specification covers uncoated, direct-drawn deformed wire for prestressed concrete tendons used in railroad ties. 1.2 The values stated in either inch-pound units or SI units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. Combining values from the two systems may result in nonconformance with the specification. |
