Organization: ASTM
Publication Date: 1 March 2006
Status: inactive
Page Count: 6
ICS Code (Metal fittings): 23.040.40
scope:

This specification2 covers wrought carbon steel and alloy steel fittings of seamless and welded construction, covered by the latest revision of ASME B 16.9, ASME B 16.11, MSS-SP-79, and MSS SP-95. Fittings differing from these ASME and MSSVF standards shall be furnished in accordance with Supplementary Requirement S58 of Specification A 960/ A 960M. These fittings are for use in pressure piping and pressure vessel service at low temperatures.

Optional supplementary requirements are provided for fittings where a greater degree of examination is desired. When desired, one or more of these supplementary requirements shall be specified in the order.

This specification is expressed in both inch-pound units and in SI units. However, unless the order specifies the applicable "M" specification designation (SI units), the material shall be furnished to inch-pound units.

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.

A Summary of Changes section appears at the end of this standard.

2 For ASME Boiler and Pressure Vessel Code applications see related Specification SA-420 in Section II of that Code.
