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.
