4.2 Definitions of Terms Specific to This Standard:
4.2.1 coil—a length of the product wound into a series of connected turns.
4.2.1.1 Discussion—
The unqualified term “coil” as applied to “flat product” usually refers to a coil in which the product is spirally wound, with the
successive layers on top of one another. (Sometimes called a “roll.”)
4.2.2 flashing, n—an impervious lead-coated copper sheet or strip used in a building envelope to create a barrier to prevent water
penetration or direct the flow of moisture.
4.2.2.1 Discussion—
This can include, but is not limited to, the heads of windows and doors, the edge components of roof systems, changes in building
planes, around chimneys, roof vents, skylights, decks and other penetrations, and other conditions requiring a watertight or
water-shedding solution.
4.2.3 lead-coated copper sheet (for building construction), n—a rolled flat product over 24 in. (610 mm) in width and of
ounce-weight thickness from 8 oz (227 g) to 48 oz (1361 g).
4.2.4 lead-coated strip (for building construction), n—a rolled flat product up to and including 24 in. (610 mm) in width and of
ounce-weight thickness from 8 oz (227 g) to 48 oz (1361 g).
4.2.5 lengths, mill, n—straight lengths, including ends, that are conveniently manufactured in the mills.
4.2.5.1 Discussion—
Full length pieces are usually 8, 10, or 12 ft (2.44, 3.05, or 3.66 m) 8 ft, 10 ft, or 12 ft (2.44 m, 3.05 m, or 3.66 m) and subject
to established length tolerances.
4.2.6 ounce-weight—the weight of uncoated copper sheet or strip expressed in ounces per square foot.
