    1. Scope

    1.1 This specification covers round, square, rectangular, and special shape, electric-resistance-welded mechanical tubing, either zinc-coated (galvanized) after welding or produced from aluminum-coated, zinc-coated (galvanized), zinc-iron alloy-coated (galvannealed), or 55 % aluminum-zinc alloy-coated steel sheet. Tubing for use as electrical conduit (EMT) or intermediate metallic conduit (IMC) is not covered by this specification.

    1.2 This specification covers mechanical tubing with outside diameters or maximum outside dimensions ranging from 1/2 to 8 in. (12.7 to 203.2 mm) and wall thickness from 0.028 to 0.134 in. (0.71 to 3.40 mm).

    1.3 Sizes outside the ranges listed above may be ordered provided all other requirements of the specification are met.

    1.4 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.
