- Temper (if the applicable material specification requires this detail),
- Form (plate, sheet, or strip),
- Dimensions (thickness, width, and length),
7.1 Thickness shall be ordered to decimal or fractional thickness. The use of the gauge number is discouraged as being an archaic term of limited usefulness not having general agreement on meaning. The gauge number shall not be a basis for rejection.
7.2 Thickness, width, and length, when applicable, should be ordered in the same units, for example, 0.060 by 48 by 120 in. [1.52 by 1219 by 3048 mm]. - Edge, strip only,
