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.
