1.1 This specification covers asbestos-cement roofing shingles, including accessories, designed to provide the weather-exposed surfaces on roofs of buildings. 1.2 Shingles supplied under this specification are of the following types as to shape and method of application: 1.2.1 American Method—Uniform thickness, generally rectangular in shape, with straight or irregular edges. They are intended to be laid with a minimum 2-in. (51-mm) head lap and with no side lap and to provide double coverage. They may be made either as individual or multiple units to simulate the appearance of individual shingles. 1.2.2 Strip Shingles—Uniform thickness, various shapes and designs to provide top lap only and shingle coverage under the butt joints, with the design such that it provides only single coverage. 1.2.3 Strip Shingles—Uniform thickness, various shapes and designs to provide top lap only and shingle coverage under the butt joints, with the design such that it provides only single coverage. 1.2.4 Dutch or Scotch Method (Including Ranch Design)—Uniform thickness with straight or irregular edges and designed to be laid with a lap at the top and on one side of each shingle. 1.2.4.1 Dutch—Square in shape. 1.2.4.2 Ranch—Oblong-rectangular in shape, with the greater dimension horizontal. 1.2.5 French or Hexagonal Method—Uniform thickness, square in shape, having at least three corners clipped to give the desired pattern when the shingles are laid with their diagonals perpendicular to the eave of the roof, with their apex sides lapped. 1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 1.4 Warning—Breathing of
asbestos dust is hazardous. Asbestos and asbestos products present
demonstrated health risks for users and for those with whom they
come into contact. In addition to other precautions, when working
with asbestos-cement products, minimize the dust that results. For
