ASTM A 822/A822M : 2004 : R2015

1.1This specification covers nominal wall thickness, seamless, cold-drawn carbon steel tubing intended for use in hydraulic systems and in other similar applications where forming operations require tight radius bending and flaring.

1.2Tubing sizes and thicknesses usually furnished to this specification are ¹/₈to 3¹/₂in. [3.2 to 88.9 mm] in outside diameter and 0.035 to 0.134 in. [0.9 to 3.4 mm] inclusive, in nominal wall thickness. Tubing having other dimensions may be furnished, provided such tubing complies with all other requirements of this specification.

1.3Mechanical property requirements do not apply to tubing smaller than ¹/₈in. [3.2 mm] in inside diameter or 0.015 in. [0.4 mm] in thickness.

1.4Optional supplementary requirements are provided and, when desired, shall be so stated in the order.

1.5The values stated in either SI units or inch-pound units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.
