2. ASTM A179 /ASME SA179 covers tubes 1/8 to 3 in. [3.2 to 76.2 mm], inclusive, in outside diameter. Note 1Tubing smaller in outside diameter and having a thinner wall than indicated in this specification is available. Mechanical property requirements do not apply to tubing smaller than 1/8 in. [3.2 mm] in outside diameter or with a wall thickness under 0.015 in. [0.4 mm].

2 .ASTM A179/ASME SA179涵蓋外徑為1/8至3英寸[3.2至76.2毫米]的管子。注1可提供外徑小於本規範所示壁厚的管子。機械性能要求不適用於外徑小於1/8英寸[3.2毫米]或壁厚小於0.015英寸[0.4毫米]的管子。

3. 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. The inch-pound units shall apply unless the “M” designation of this specification is specified in the order.

3.以英寸-磅單位或國際單位表示的值應單獨視為標準值。在文本中，國際單位製顯示在括號中。每個係統中所述的值不是完全等效的；因此，每個係統都必須獨立使用。將兩個係統的值結合起來可能會導致不符合規範。除非訂單中指定了本規範的“M”名稱，否則應采用英寸-磅單位。
