ASTM A513
Standard Specification for Electric-Resistance-Welded Carbon and Alloy Steel Mechanical Tubing
What it measures
Covers welded mechanical tubing and its dimensional tolerances.
Why it matters for a panel envelope
Tolerances matter in a factory-built panel, where a member that is out of dimension shows up as a panel that will not sit square.
