What to know before ordering to ASTM A269
The points that decide whether material to ASTM A269 is accepted at inspection.
- Sizes are given as OD and wall thickness, down to small instrumentation tubes.
- Hardness limits matter for compression-fitting tubing; specify them when needed.
- For pressure pipe, ASTM A312 is used instead.

How ASTM A269 fits into an order
A purchase order line is only complete when it names the material standard, the dimensional standard and the inspection document. Miss one and the mill, the inspector and the buyer can each read the order differently.
