2、e yearof original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval.A superscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope*1.1 This specification2 covers nominal (average) wall
3、 seamless and welded carbon and alloy steel pipe intended for use at lowtemperatures and in other applications requiring notch toughness. Several grades of ferritic steel are included as listed in Table 1.Some product sizes may not be available under this specification because heavier wall thickness
4、es have an adverse effect on impactproperties.1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. Within the text, the SI unitsare shown in brackets. The values stated in each system may not be exact equivalents; therefore, each system shall be use
5、dindependently of the other. Combining values from the two systems may result in non-conformance with the standard. Theinch-pound units shall apply unless the “M” designation of this specification is specified in the order.NOTE 1The dimensionless designator NPS (nominal pipe size) has been substitut
6、ed in this standard for such traditional terms as “nominal diameter,”“size,” and “nominal size.”2.
