This Standard includes the following information for Inverted Tooth (Silent) Chains: (a) Nomenclature; (b) General configuration; (c) Numbering system; (d) Tolerance for chain length; (e) Measuring loads; (f) General chain dimensions for 3/8 in. pitch chain and larger; and (g) Chain widths and sprocket-face profiles for 3/8 in. and larger pitch chain and for 3/16 in. pitch chain. This Standard also includes the following information for sprockets: (a) Tooth form dimensions for 3/8 in. Pitch Chain and larger and for 3/16 in. pitch chain; (b) Diameters and measuring dimensions for 3/8 in. Pitch Chain and larger and for 3/16 in. Pitch Chain; (c) Tolerances for diameters, over pin dimensions and eccentricity for 3/8 in. and larger Pitch Chain and for 3/16 in. Pitch Chain; (d) Hub diameters for 3/8 in. Pitch Chain and larger; (e) Tabulation of pitch diameter, outside diameter, over pin dimensions and guide groove diameter for 3/8 in. Pitch Chain and larger and for 3/16 in. Pitch Chain. Also included is "Supplementary Information" which contains suggestions relative to the application and use of the chains covered by this Standard.
